The fruit thrown at Wallace as he is being led to his execution includes tomatoes. The tomato was not introduced to Europe from the Americas until the early 16th century, over 200 years after Wallace's death.
Wallace is asked to kiss the royal ensign during his torture, but this is a rose. Edward I was a Plantagenet king who used the Fleur de Lys as their emblem. It was not until the Tudors, nearly 200 years later, that the rose was used as a royal ensign.
After the defeat of his cavalry at the Battle of Stirling, the English commander orders his "infantry" to advance. Infantry as a word was unknown anywhere in Europe in the 13th century. The term arose in 16th-century Spain, where royal princes--or "Infantes"--were given military commands, and their men became known as "Infantería". The term the commander should have used was "Foot."
After Morrison's wedding, the English noble arrives to claim the right of Prima Nocta. When Morrison attempts to fight, his bride calms him by whispering in his ear. While whispering, she is clearly saying, "It'll be OK". The term "OK" was not coined until the mid-19th century.
At the funeral of William's father, purportedly around 1280, bagpipes are played. William's uncle says they are "playing outlawed tunes on outlawed pipes." Bagpipes weren't introduced to Scotland until the early 1300s, and even then they were in a more basic form. The "banning" of the pipes wouldn't occur until 1745, more than 250 years after the movie takes place--and even then there is some dispute as to whether they were included in the ban as "instruments of war".
After Stephen (the Irish) volunteers to fight in William Wallace's army and says that he came to the right place, he laughs. At this moment, we can see that some of his upper molar teeth have modern amalgam fillings.
The scene when Hamish father is shot with an arrow then breaks the end off. The arrow is a hallow shaft arrow, which wasn't made during the time frame of movie, he then gets up lifting the log gate to let the other fighters in the arrow is a solid shaft arrow which is continuity.
Isabella of France and her retinue are shown speaking French, while King Edward and everyone at the English court speak English. In fact, they all would have spoken the same language: French. Edward's native language was also French. English would not become the court language in England for another 100 years.
The film's narrator, Robert the Bruce, describes himself as the 17th person successively named Robert Bruce and the 17th Earl of Bruce. In reality, Robert the Bruce was the 7th Robert Bruce and the 7th Lord of Annandale.
In the scene with young Wallace and Hamish hiding on the mountain as the English ride by, when the two stand up and throw rocks at the skulls, young Wallace throws the rocks with his left hand. Later when Wallace returns to the village and Hamish challenges him to the rock throwing contest, Wallace throws with his right hand.
Wallace uses incorrect Latin when he says "ego numquam pronunciare mendacium". His use of the infinitive form "pronunciare" makes no sense. He should have used the simple first person singular: "ego numquam pronuncio mendacium". This is a very basic mistake that someone as well-educated as Wallace should not have made.
When Longshanks announces he is re-instituting "Prima Nocta" to his advisers, Isabella looks confused, prompting him to tell her it means "first night" and entitles the local lord to sexual rights with common girls on their wedding night. Later, when Isabella first meets with William Wallace, Lord Hamilton speaks to her in Latin, illustrating that she actually does understand the language and should not have been confused earlier.
At the battle of Stirling it shows Wallace beginning the charge using a war hammer, the same one he used to spike the English cavalryman through the helmet with. The hammers were small and thin with a pickaxe head. It then cuts to the English overseeing the battle, then cuts back to Wallace charging with no sword in hand; he begins the charge and draws his Claymore. The movie cuts to another English scene again, and upon returning to Wallace charging into battle he has his sword nearly out. After another English vantage point he is brandishing the war hammer again and running from a side view. After one last English view, Wallace's Claymore is out and raised above his ahead as he and his men crash into the opposing army.
In the battle of Stirling a Scot is shot in the foot with an arrow. He screams and we assume that he has been defeated. During the next English archer attack the same Scotsman is shot again in the same place and yells the same way as before.
At the parlay with Wallace, Isabelle is shown wearing two different veils, a sheer tight one with a hemmed edge that covers her chin, and one thicker, looser one with a ragged edge that doesn't cover it.
Just before the Battle of Stirling, when Wallace rides up to intimidate the negotiating English commander, we can see the entire English army lined up behind him. In the next scene however, when we see just Wallace and the Englishman, the entire English army behind him has disappeared, except for a line of cavalrymen. This repeats itself.
When William comes to take Murron on a horse ride in the rain, he talks to Murron's parents. The camera cuts to Murron a couple of times, ducking under the shelter, and her hair is completely dry. But when she rushes out and jumps onto William's horse, her hair is soaked. Obviously this scene took several takes, and they didn't take the time to dry the actress's hair between each take.
In the scene where Wallace and Hamish are discussing throwing rocks while at the wedding, the shots alternate between their faces, depending on who is speaking. From one angle their hair is blowing in a breeze, from the other angle the wind is calm.
During the execution scene when Wallace is reflecting and sees his wife in the crowd. Pay attention to the axe as it is coming down on Wallace's neck. As the axe approaches, it slows down as it gets closer. The scene is in slow motion, so look close. [According to Mel Gibson, the executioner actually placed the axe near Wallace's head and then raised the axe. The scene was shot in reverse for the movie. Doesn't make it less of a mistake, but explains it - the axe was accelerating, so in reverse it looks like it was slowing down]
When Longshanks opens the basket and lifts the head clear, he drops it back in the basket with the leather cover off. After he knocks Edward down he sits at the table and the leather cover is clearly on.
At the Battle of Stirling, up the point when the cavalry charges, the area at the foot of the Scottish soldiers, as well as shots deep into the Scottish army, show no evidence of the large spears. Just as the cavalry is nearly upon the Scottish army, there are suddenly lines and lines of the large spears on the ground.
In the village segment immediately following the first dialogue between Robert the Bruce and his father, Mad Stephen can be clearly seen fighting an English soldier behind Hamish. In a later scene, Stephen is introduced to Wallace and his followers as a complete stranger.
During Murron's funeral, one of the guests standing behind William Wallace is easily identified as MacGregor. In a later scene MacGregor runs up breathless at the head of a group of highlanders to join Wallace, saying, "We heard about what happened here . . . ".
After the battle at Falkirk and after being beaten before he's taken captive, Wallace is obviously bloody and cut all over his face. When he is cleaned up after each, he only has one wound; the same exact diagonal scratch from his hairline.
In one of the major battles, Wallace is charging down a hill with a large sword in his hand. During the charging it changes to being a small pick axe type tool. Then around the middle of the charge there is a quick shot change and almost from the same angle the pick axe has disappeared. It then changes back to a large sword, a quick change back to the pick axe, then back to the large sword.
When Wallace first meets Princess Isabelle and is left alone with her in the tent, the wimple she is wearing appears to have a life of its own - first it's on her chin, then over her chin, and then under her chin.
In another major battle scene William Wallace is running into battle with a bloody claymore in his hand. In the next shot of him it is back in its sheath. Then in another scene he has it in his grasp again, but this time it is clean.
At Stirling an English archer is hit by the nobles on horseback causing his helmet to fall off. He's then hit again and somehow his helmet falls off again. Then when he lands he is still wearing his helmet despite it having fallen off (twice).
When the English spy tries to kill Wallace, and you realize the crazy Irishman is a friend, you see the spy drop his sword, as soon as he is hit by the Irishman's weapon, but as soon as he hits the ground dead, the sword is back in his hand.
When Wallace tries to escape from the English with his wife, not knowing that she has been captured and executed, he is seen running through the woods screaming her name... As he's running he has a sword in his right hand. During the course of three or four camera shots, the sword he is holding magically disappears and reappears as different cameras shoot him. Then it reappears and he digs it into the ground as he takes off the English soldier's uniform that he stole.
While the English cavalry is charging the spikes, as William Wallace is shouting "Hold!", the camera cuts to a cavalry point of view, and it can be clearly seen that the spikes are up before Wallace gives the order. This happens two or three times.
At the end, when the main executioner bends down, his cloak shifts and you can see he is wearing brown shoes with red rubber soles. These rubber soled shoes are worn today and had not been invented yet.
During the scene in which William Wallace is being executed, the camera pans the crowd and shows the ragged peasants staring in silence. An extra, who is a young woman with light hair and a dirty face and is standing near the front of the shot, stares directly at the camera for a few seconds while all the other extras look in a different direction towards the execution.
In the first large battle with England at Falkirk the same scenes are used when the English fire the arrows. The first time the arrows are fired, a blonde young man is hit in the foot, they then moon the English so they fire again and the same man is seen getting hit in the same foot. A man in the same battle is shot in the hip - when he grabs the wound you can see the shape of the cushioned bulb that the arrow is attached to. If you watch during all the battle scenes you can detect men who are supposed to be on opposite sides standing and talking, also you can see the choreographed moves being played out in almost slow motion - their swords aren't even striking.
At the very end of the movie, watch the man standing to the left of the Bruce at Banickburn. In a shot from behind, there is a man with very short and curly hair. In the very next shot, from the front this time, a different man with very long and straight hair is to Robert's left.
When Wallace arrives at the home of Murron to invite her for a ride in the rain, the mother's head covering changes several times between shots. Sometimes it has the yellow fringe close to her face and other times it does not have the fringe at all.
Just before Wallace picks up the archer to throw him over the ledge, you can the archer has a tin looking hat around his head with part of his suit covering his head below the hat. In the shot from in front of the ledge when Wallace is throwing him off the cap has now disappeared before he has been thrown. The following shot as he is falling its a bit hard to see his cap but you see it come off.
When Smythe and his two men watches Murron and Wallace as they walk away from each other, you can see Smythe sitting and both of his men are standing in front of him. When it cuts, both his men are standing behind him, and he is suddenly wiping his mouth.
At Sterling right after the first arrow attack by the English men, you can see Wallace getting up with his shield in front of him. We can see one arrow attached to his shield, however when it cuts he has two arrows attached to the shield.
In the first battle scene (the first one with Wallace and the blue paint), when Wallace is charging the English you see him grabbing for his sword. In the next scene his arms are at his side. In the scene after that, he is grabbing for his sword again.
During the funeral for Wallace's father and brother, various people change positions. Murron starts out in front of her mother, frame left, then is in front of her father, frame right, then is back in front of her mother. Campbell and Hamish start out beside Wallace, jump to about 18 apart, then behind Wallace, then back to about 18 inches apart.
Near the end of the battle of Stirling (the first big one), an English officer on a horse comes at Wallace. Wallace swings his sword at the feet of the horse, knocking it and the officer down. As the officer falls his sword goes from one hand to the other several times.
When Wallace is saved by Steven, right after he meets him, watch Steven as he is about to throw the small sword. When he comes out of the brush and starts running, he gets past the two trees in front of him, then it cuts to Wallace aiming his bow at him, then it cuts back to Steven and he is back behind the trees.
During the funeral scene for Wallace's wife we see the leader of the group of Scots that show up later in the film (after the attack on the local fort). Nobody seemed to know him but he was at the funeral with all of them...
At the wedding scene near the beginning of the film, Wallace challenges Hamish to throw a large rock at him. He throws the rock, and in slow motion the rock is clearly on Wallace's left side; he even leans a little to his right as the rock starts to pass by on his left. But in the next angle the rock is very clearly on his right.
Near the beginning when the boy is waiting for the men to return and he has the bucket of water, you hear the water slosh but the scrawny boy runs so effortlessly with it and you never hear it slosh again. Then when he is at the fence with his back to them, you see the bottom of the bucket is wet, but there's no water in it.
There are scenes edited out of sequence. It is just after the fight scene where Wallace and other Scots storm the fort and Wallace kills the old guy that killed his wife. Well, in that scene, Hamish's father was struck in the shoulder with an arrow, and everybody is dirty and bleeding from the fight. The very next scene we see everybody cleaned up and fine at Wallace's wife's funeral, even Hamish's father can be seen without the arrow in his shoulder. Now, the scene after that, everybody is bloody and dirty again and they are removing the arrow from Hamish's dad. The funeral was edited out of sequence.
As the horses are charging towards the Scots at Stirling, there's a shot of Hamish's father waiting to attack. Take notice of both his shield and the soldiers' behind him. There are no arrows anywhere.
Watch the group of English soldiers that ride out to present the King's terms at Stirling. After Wallace insults them, they turn around and begin to leave. The sounds of their horses riding off are very audible. After Wallace's talk with the three nobles, their group breaks up and begins to ride back. A panoramic shot of the field is shown and the English representatives have just started to leave.
When Wallace is pretending to surrender after the English killed his wife, he is on a horse and he puts his hands behind his head. In all the shots from in front his hands are high on his head, in all the shots from behind his hands are low on his neck.
In the battle scene where they flanked their forces and and were going to use the long wooden spears on England's knights, they already had the spears out when it showed England's horses coming closer. Just look around them. It only shows for a second when it is zooming in pretty fast.
In Wallace's father's burial scene, when the young girl goes to give William the thistle, the camera goes to just their hands which are supposed to be those of young children. They are however clearly the hands of an adult woman and man.
During the archer volley phase of the Battle of Stirling, several of the Scots are hit while defending their position. However, the same Scot, a younger man with middle-parted hair, is shown being hit several times during the different arrow volleys, having apparently fully recovered prior to each attack.
During the battle of Stirling, you can clearly see that the stuntman (playing the English negotiating officer) that Wallace beheads after knocking him off his horse changes in different shots as he approaches on horseback.
Just before the Battle of Falkirk, Edward is talking to Robert Bruce with a helmet on and The Bruce is on Edward's left. The camera angle changes to Edward's right side and The Bruce is on Edward's right. This happens two or three times.
When Wallace, Hamish and Stephen burn the hut with the English soldiers inside watch for a fourth man who appears for one shot only then disappears. He also has a torch despite Stephen only lighting three.
When William realizes that the Bruce has been bought by the King, he gives up and lies on the ground. Earlier, he had been hit with an arrow and if you look hard you can see the arrow move when he lies down. This shows the arrow to be attached to his clothing and not actually piercing his body.
In the scene where William Wallace charges after the king's brigade after the Battle of Falkirk, and Robert the Bruce (disguised) turns and charges at him with a lance, Robert is wearing two distinctly different silver helmets before he hits Wallace and after. These two helmets are seen interchangeably in the preceding scenes also.
During the first major battle scene, Wallace's sword has a leather looking binding around the blade at the hilt. As the battle progresses, the binding moves a third of the way down the blade and then back again.
In the prison cell scene, after Princess Isabelle enters the cell and the jailor leaves, the jailor leaves the cell door half closed. The camera moves to William again then back to Princess Isabelle and the door is now fully open.
In the scene where Wallace surrenders to the local magistrate, after Wallace has struck the English soldier that was holding the reigns of the horse, a second soldier attacks the horse with a spear. The spearhead is seen as the soldier starts the attack, after the cut the spearhead is gone, before it strikes the horse. The un-headed spear then hits the harness of the horse where it sticks as the horse rears, and the harness moves from the front of the horse's neck between the legs of the horse to the side, somehow passing through the raised legs of the horse.
After Murron's funeral, Wallace kneels before her father, who at first makes a fist, then places his hand flat on Wallace's head. His palm is down, fingers outstretched. But when it cuts to the wide shot, he's suddenly gripping Wallace's hair in his fist.
When Wallace was first seen approaching the deer, he already had the bow and arrow ready, he would just need to draw back and shoot. But in a close up shot of Wallace, he was just taking out an arrow to get it ready.
When the spy was trying to kill Wallace, he was seen swinging his sword forward. The shot cut to Stephen throwing his knife. When the shot cut back to the spy being hit by Stephen's knife, he was pulling back his sword to get ready for a forward swing. What? Did he miss on his first attempt and had to try again?
At Falkirk the order in which Longshanks, Robert the Bruce and the English soldier are standing changes from shot to shot. In some shots Bruce is between the soldier and Longshanks and in other shots the soldier is between Longshanks and Bruce without the actors ever moving.
In the scene where Longshanks returns from France, confronts Prince Edward, and the soldier has left the basket with the head of the Prince of York, Edward reaches to remove the cover with his left hand, his right hand is on his hip. When the angle changes he is lifting the cover off with his right hand and his left is on his hip, when the angle cuts back, his right hand is back on his hip and his left hand is moving away from the basket.
At Stirling when the Scottish attack on horse, there is a scene where an Englishman is being sliced by a sword and is quite bloody. Then it cuts to him being run over by two horses and you can see that it is not the same man nor are there any traces of blood on him. Then it cuts to him falling to the ground and he is again quite bloody.
Right after Wallace has been riding with Murron when MacClannough and some other men gets to Wallace's, as MacClannough says "You want to stay out of the trouble?". You can see Wallace standing with his arms to his waist. When it cuts his arms are down.
In the first battle where Wallace is attacking the palisades and he is riding slowly, pretending to be unarmed and later draws a morning star/flail from behind his hair, the morning star/flail obviously isn't there until he needs it.
When Wallace pounds an English soldier with a large mallet, in the village where his wife was killed, watch the third hit. Wallace hits the soldier in the hip and then in the back. On the third hit, the mallet comes down at least an inch or two from the soldiers head, missing. The soldier jumps as if he was hit.
When Wallace was in the bedchamber of a noble lord, he takes out a chain with a ball at the end. The chain is wrapped twice around his fist, and the ball is dangling under his fist; however, when Wallace swings the weapon, the chain is leading outwards from the top of his fist.
When Philip is thrown out the window by King Edward we see him flipping over in the air so that he will hit the ground on his back. But when the camera changes to the window view we see that Philip is lying on his front.
At the end of the movie the executioner bends down to bind William's feet. The scene shows the rope starting around his feet and then a second later William is yanked into the air with a complicated noose-like knot holding his lower body to the ground. How did they make that knot so fast?
During the scene in which Steven (the crazy Irishman) joins up with William Wallace and they converse about killing Englishmen and such, pay attention to Steven's forehead. It's very obvious that the scene was composed of multiple takes because of the way that repeatedly throughout the scene Steven's hair changes. There are a couple of locks of hair that go from being stuck across the middle of his forehead to being off to the side with the rest of his hair.
When Wallace is at his brother and father's funeral at the start of the film, Hamish's and Murron's father are both in attendance. Let's say that this is about 20 years prior to the first battle at Stirling in 1297. 17 years later, the battle at Bannockburn takes place, yet Murron's father is fighting in it, looking not a day older than at the funeral scene which was supposedly almost 40 years prior to it. And when Hamish's father dies at Falkirk, he looks no older than at the aforementioned funeral scene. A miracle anti-ageing cream perhaps?
When the horses are charging right before they jump over a little mound of earth, before they strike the long spikes of the Wallace's soldiers, you can see a car behind the horses after they jump. I have only seen this on the wide screen version of the movie.
At the funeral of William Wallace's wife, Murron, a white van can be seen. He bends down to kiss her and as he stands back up, if you look over his left shoulder through the trees you can see the van going past. It's very quick, small, and blurred, but it's there.
In the execution scene at the end, right as Wallace is being quartered, you can clearly see (on widescreen) a plastic spray bottle on the upper left part of the screen, presumably filled with fake blood.
When Wallace throws one of the archers down from the tower, as he falls on the roof below him. Look down to the left of the screen. You should be able to see a man in a dark grey shirt standing beside a camera.
At Stirling right before Wallace drops his sword and picks up an axe you can see some black duct tape on his sword. A man then swings his sword at the exact position of the duct tape. This is an obvious test take where they rehearse the scene, and was not meant to end up on screen.
When Wallace captures the fort of the noble who killed his wife, he pushes said noble down a hill before putting him to the post and slitting his throat. If you watch when the noble is pushed, he rolls over and the cape uncovers the back of his costume. You can see blue pants that look like jeans under his costume.
The landscape in the opening credits and early scenes is the Western Highlands (specifically Glen Nevis) which look utterly unlike the Western Lowlands where Wallace grew up. Wallace never visited the Western Highlands.
Wallace and many other Scottish characters ride horses while dressed in kilts. Even in times and places where the kilt was actually worn (it wasn't worn anywhere in Scotland in Wallace's time, and at no time in history was it worn in Wallace's part of Scotland), men who expected to ride anywhere wore trews, not kilts, for the very good reason that it would have been an extremely painful and impractical experience; no underwear was ever worn under the kilt. Kilts were not invented until the 16th century, more than 200 years after the events in this film.
The film depicts William Wallace as having an affair with Isabella, the wife of Edward II, and implies that he fathered her child, the future King Edward III of England. In reality, Isabella was only two years old at the time the film depicts the affair happening. She would not marry Edward until three years after Wallace's death and her son, the future king, was not born until seven years after that.
The Battle of Stirling was actually the Battle of Stirling Bridge (September 11, 1297). The "spears" were far from a new idea and were not employed there. However, Wallace did divide the army, trapped the English cavalry on the bridge and the Infantry in the mud on each side. In their heavy armor, many of the English died by drowning in the mud.
The film shows King Edward I (the Longshanks) dying just before Wallace was beheaded. Wallace was executed on August 23, 1305. King Edward I died on July 7, 1307, while leading another invasion of Scotland.
Sir William Wallace was already a knight and a minor member of the Scottish nobility (mostly owing to his father, Sir Malcolm Wallace) even before the Battle of Stirling Bridge, which is not depicted in the film.
Although the closing narration talks about the Scots winning their "freedom" at the Battle of Bannockburn, the peace treaty of 1328 only lasted for a few years before the Battle of Halidon Hill where King Edward III conquered far more of Scotland than his grandfather ever had.
When William Wallace is seen in action during the first fight (Battle of Stirling Bridge) he is seen performing cuts and slashes that are virtually impossible to perform with his very long--and heavy--two-handed sword (called a claymore).
At the funeral of Wallace's father, the child Murron plucks a thistle, the national flower of Scotland, and gives it to the boy Wallace. This is both physically impossible (every species of thistle in the British Isles is so prickly and so tough-stemmed that you could only wrench one from its stem wearing protective gloves) and symbolically absurd (the toughness and prickliness of the thistle is its whole point as a symbol of Scottishness).
After William Wallace's knighting ceremony, one of the nobles asks him to support the Balliol clan's claim to the Scottish throne. This would be impossible, since John Balliol had already been crowned king a few years earlier with the support of Longshanks, and had abdicated the year before the Battle of Stirling Bridge.
The film depicts a longstanding English occupation of Scotland, implying that it existed since at least Wallace's childhood. However, the invasion began only the year before Wallace's rebellion started.
At the battle of Falkirk, the Irish soldiers fighting for Edward change sides at the last moment and go over to fight with the Scots. In reality, there were no Irish troops present at the battle. The only troublemakers amongst the English army were the contingent of Welsh bowmen who showed a reluctance to fight Wallace but this was more out of fear rather than sympathy for the Scots.
The voice-over at the beginning of the film tells us that Malcolm Wallace was a commoner with his own lands and constant references are made through-out the film to William being a commoner. However this is a common historical myth. Malcolm Wallace was in fact born as a minor noble and became a knight, as was William. They were poor as noble families went but were still infinitely more privileged than the commoners of the day.
In the opening scene of the film a caption at the bottom of the screen tells us it is Scotland 1280 AD and the voice-over tells us the King of Scotland had died without an heir etc. But Alexander III of Scotland did not die until 1286 AD.
The film hints that Wallace is the father of Isabella's child (and the ancestor of all future kings and queens of England) but Isabella's baby (the future Edward III) was born in 1312, seven years after Wallace's execution in 1305.
The reason why it is called the Battle of Stirling is because it was fought on Stirling Bridge, in mud. The English had to file down into small ranks so they could cross the bridge, while William Wallace came in with full plate armour, not kilts, and butchered them with the rest of the Scots.
Malcolm Wallace had three sons: John, William, and Malcolm. He was not killed in a minor scuffle with the English. He, in fact, fought for several years with the English in order to free John de Baliol from the tower of London. At the time, Baliol was the rightful heir to the Scottish crown, and that was actually William's reason for fighting the English. Robert the Bruce was the one who actually liberated Scotland.
During the Battle of Falkirk, Wallce (in the movie) waves towards Lochland & Mornay to use their cavalry. A few seconds before he does so, a soldier is attacked & killed. If you use slow motion, that solider is played by none other than the actor Angus Macfayden (aka Robert the Bruce).
Irish whiskey was common at the beginning of the 14th century and had been around for about 200 years, so it's unlikely the Scots would have had a problem getting any. When some of the village men are about to tend to old Campbell's arrow wound with the aid of a jug of spirits, Campbell says, "It seems like a waste of good whiskey." However, the production of "uisge beatha" did not begin in Scotland until about 200 years later.
English in the 13th century was drastically different from modern English. The characters in the movie, however, speak modern English, which naturally includes a huge amount of vocabulary not used in Wallace's time. This is clearly an artistic decision, not a mistake. Think of it as a "translation" of what they were "really" saying.
This is neither a biopic nor a historical documentary but is, rather, a romantic fiction inspired by true events. Many of the "real" characters and events have been deliberately re-interpreted to suit the story, as have some details of costume and custom. Despite this, both Randall Wallace (writer) and Mel Gibson (director / star) consistently touted this film as "history" and "historical fact" when it was released.
As Murron tries to escape on the horse we can see the blood spatter all around her mouth prior to being struck by the staff (and knocked from the horse).
In the events preceding her escape, she bit a chunk of flesh from the cheek of one of the Englishmen who was attempting to rape her. This is where the blood came from.
The "thistle bloom" that young Murron gave to young William at the funeral was clearly a silk flower--no surprise then that when William produced it many years later to show Murron that it was still bright (and silky shiny) purple and green, rather than dull and crumbly.
When we first see Edinburgh, where Robert the Bruce welcomes the council of nobles, a stable boy in a red tunic is standing behind Bruce, Mornay and Craig. The scene takes place in 1296. When Wallace is captured in 1305--nine years later--we see the same boy in the same tunic, and he hasn't aged.
During the Battle of Stirling, as Wallace meets up with Mornay (on horse), an English soldier in the background is run through by a spear. He acts out the injury, turns around, and continues fighting, as if nothing was wrong.
When William Wallace rides into Mornay's bed chamber on the horse and jumps into the water, you can see how the horse floats, it being a fake horse. Also, the horse falls into the water upside down, which a real horse would not do. When Wallace and the horse are falling, the scene is shown in slow motion, making it easy to identify that it is the stunt double, not Mel Gibson.
At the end of the first battle, when William Wallace is standing looking upon the field, the nobleman arrives on his horse to salute Wallace because of their victory. In the background, an Englishman and a Scot are fighting. They are obviously doing a repeated sequence where the Englishman pushes his sword across the Scot, a mortal blow, and the Scot just turns around and continues the sequence as if nothing happened.
Just after Wallace realizes Robert the Bruce was fighting with the English, he is lying on the ground with an arrow in his chest. The piece of shaft gets caught on his hair and it moves around freely showing that it isn't really in his chest, just maybe stuck to his shirt.
After Wallace kills the Scottish noble in bed, he jumps out of the castle window into a river on a horse. As he is falling, you can see that the horse is a model and when they fall into the water one can see the fake horse bobbing around.
As the funeral of young William's father and brother is over, a man lifts a shovelful of dirt and empties it onto the open grave of one of the men. As he does this you can see the fake body that is wrapped up bounce pretty hard, revealing that it is not in fact a real person but something made out of lightweight material.
When Wallace rides into the village after his wife is killed, he hits the foot soldier with the mace-like weapon. When his horse is lanced, note that the lance is actually attached to the leather girdle on the horse, so, in effect, the animal is merely being pushed over.
At the end of the battle of Stirling we see a Scotsman stab something with his sword and we can hear "Ouch.". However there is no one on the ground where he stabs. He just rams the sword into the ground. Then he does it again and we hear "Ouch.". Quite fun to watch.
In the scene where Wallace comes back (right after his wife is killed), he throws two archers out of the tower. The second archer is supposedly killed on the palisade wall; but right before the camera changes, you can see the wall bending as he lands on it.
Something very strange happens at the battle of Stirling. An arrow can be seen near William Wallace's right shoulder even before the English archers start shooting. Now where did that come from? It's there for about a second, so look closely.
During the Battle of Stirling, several combatants can be seen goofing around in the middle of the battle. Notably near the end of the conflict, an English soldier and a Scot can be seen taking deliberately slow and exaggerated swings at each other and laughing.
When the cavalry is charging the army, in one quick shot you can see a very fake horse do a flip when it reaches the front line. It's head is way down and the legs don't move, even when it's 'running'.
When Hamish throws one of the English soldiers off his stand and he flies on to some wooden spikes, you can actually see the spikes bend as he falls between them. However when it cuts the man is suddenly impaled by one of the spikes.
In the scene where Princess Isabelle gives Wallace the remedy to dull his senses, she pours the liquid in his mouth and then kisses him. Then on her way out, you can see Wallace swallowing before he spits out what is supposed to be the poison.
During the first large battle between the Scots and the English, there is a clear, quick shot of an English soldier getting quite eviscerated on the right side of his body. For a fraction of a second, you can see a couple drops of blood splatter against some sort of protective glass between the camera and the soldier.
After Wallace makes love to Isabelle he rides off and is then part of a group riding down a long and winding road. Far off in the distance (at the bottom of the hill) a car or van can be seen moving towards the camera.
When Princess Isabelle visits William Wallace in the dungeon, she orders the gaoler (jailer) to leave the room, and he pulls the door closed slightly. This is viewed with an over-the-shoulder angle from Wallace. The shot then cuts to the Princess, then back to the over-the-shoulder shot, where we see the door is open farther than where the gaoler pulled it closed.
In the scene where Murron has her throat slit, William's face is splattered with blood, then at her funeral his face is clean, but in the scene after her funeral his face is again splattered with blood.
As Wallace approaches the fortress on horseback to avenge the death of his wife the camera shows his hand behind his head underneath his hair grasping the weapon he uses to hit the guard. As the angle changes his hand appears outside his hair and then underneath again as he pulls the weapon.
During the execution scene, the executioner, ready to behead Wallace, raises his axe over his head with both hands. The movie cuts from him. When the movie cuts back to him, he has the axe raised over his right shoulder rather than over his head.
After William is shot by an arrow at Falkirk, he breaks the arrow, leaving the shaft in his chest. When he is shown lying back onto the grass, the shaft is gone, but then it returns again in later shots.
When Nicolette is telling Isabelle (the Princess of Wales) about Wallace taking Murron's body to a secret place, Isabelle is sitting leaning forward. Isabelle then sighs, sits up straight and leans her head against the post that is to her right. Immediate cut back to Nicolette, and Isabelle is leaning forward again as Nicolette reaches out to hug her.
When Steven pulls the sword out of Faudron's chest and exits camera right, if you slow down the action you can clearly see that the sword is cut off almost to the hilt with two male nipples sticking out of the sword that were inserted into obviously two holes in a chest plate on Faudron to appear as though the sword was deeply embedded in his chest.
