Crew or equipment visible: After the last sword fight in the wheat field, as Edmund retreats back into the building, a crew member can be seen in one of the windows.
Anachronisms: During the last sword fight in the wheat field, large overhead power lines are clearly visible in the valley. A radio communications tower is also visible next to the building, off in the distance.
Revealing mistakes: When Abbé Faria and Edmond Dantes are crawling in the tunnel, Faria accidentally blows out his candle, but there is still light coming from the candle holder.
Crew or equipment visible: When Count Mondego is talking with Monsieur de Villefort in his office with the window open, you can just make out cars parked on the other side of the harbor.
Anachronisms: There is a brass and copper diving helmet in Mr. Morrel's office in 1813. The first patent for a "hard hat" or copper-collar type dive system wasn't granted until 1823.
Anachronisms: The trunks that Dantes has are Louis Vuitton, a French luggage house that was founded in 1854. The print, called Monogram, was designed by Louis Vuitton's son in 1896; the story is set in the 1820s.
Continuity: At Albert's birthday party, Mercedes clearly sits to the left of Edmond. However, in the close-ups, Edmond is seen looking to the right when looking at her.
Audio/visual unsynchronized: When Dantes and Mercedes begin the waltz at Albert's birthday party, the music clearly is of strings being bowed. The musicians, however, are plucking the strings.
Continuity: At the end of the knife fight when Dantes has Jacopo on the ground, Dantes' knife changes between shots.
Continuity: When Mercedes shows Edmond the string on her finger, she shows him her right hand. In the next shot, she is showing him her left hand.
Continuity: At the end of the swordfight in the wheatfield, when Edmond stabs Mondego, the sword goes through the right side of Mondego's chest and the viewer can see his tie fall loosely onto the protruding sword. In the next shot, when Mondego is lying on the ground, the sword is through his left side and sticking through the tie also.
Continuity: The sky during the final sword fight; when the fight begins clouds are gathering for a storm, but when Edmond stabs Fernand, the sky is breaking up and a rainbow can be seen in the background.
Continuity: At the end of movie when Dantes is standing on the cliff talking to the Priest, part of his jacket on the right is blown up to the shoulder. The next shot the jacket is laying flat.
Continuity: Edmund's eye color changes from brown to blue and back to brown continuing throughout the movie
Errors made by characters (possibly deliberate errors by the filmmakers): On the island of Elba the Emperor addresses one of the English soldiers as "lieutenant" when he is clearly wearing sergeant stripes.
Crew or equipment visible: When Edmund and Abbe are attempting to catch a rat, shoes are visible through the trap on the door right as it closes.
Anachronisms: When Abbé Faria is coming down from standing on Edmond's shoulders, you can see a paper clip holding up Abbé Faria's right rolled up pant leg.
Continuity: Dantes has been in prison for many years. When the priest digs through his floor, Dantes is cowering in the corner and has his hands by his face. Notice that his hands and nails are clean.
Revealing mistakes: Obvious stunt double during the knife fight between Edmond and Jacopo.
Incorrectly regarded as goofs: In the final scene between Edmond Dantes and Fernand Mondego, Dantes' sword is cut in half by Albert Mondego and is replaced by Fernand Mondego's sword that hung on his belt. However, in the final fight between Edmond and Fernand, Fernand draws the same sword from the same scabbard on his belt, which was previously empty. Edmond and Fernand effectively fight to the death with the same sword. The sword Fernand drew was Albert's sword which he yanked out off the young man's hand just before he threatened everyone with his reloaded pistol.
Factual errors: In the final scene between Edmond Dantes and Fernand Mondego, Dantes' sword is cut in half by Albert Mondego. This is actually physically impossible unless Dantes' sword is of a seriously inferior make to Mondego's - by this I mean that it would need to be an ornamental sword made from the cheapest metal available and even then it is unlikely. Swords, especially rapiers and other such highly-flexible fencing swords, might flex or snap but they cannot be neatly cut by another sword. Swords are designed to cut through flesh, bone and armour and would be utterly useless if they could be cut in half just by being hit by another sword. Though it would make fencing scenes a lot quicker.
Revealing mistakes: Obvious stunt double for Jim Caviezel during the two scenes when he's under water.
Continuity: When the Count lands in his balloon, the acrobats do their best to center him on the way down. Despite their efforts, the basket of the balloon lands turned slightly to the side. However, in the next shot when Edmund walks out of the basket, it's perfectly centered.
Crew or equipment visible: When Edmond and Jacobo use the skiff to travel to the island, there is an orange buoy clearly visible just ahead of them.
Anachronisms: During the movie, a scene is shown where participants are playing continuous pool (an early version of snooker). The game did not originate until 1888 yet the movie is set in the 1820s.
Crew or equipment visible: When Dantes runs along the shoreline, a blue object can be seen in the background - this must be a crew member because none of the smugglers are wearing blue.
Factual errors: Edmond and Jacapo somehow manage to carry a boat full of treasure back from the island of Monte Cristo when they go there the first time on the Skiff. With nothing but the man power of two people, it would be physically impossible to carry and load massive chests full of gold onto a boat. Not to mention the treasure was underwater, thus adding to their weight
Anachronisms: During the lavish party at the new home purchased by Dante, as Jacopo introduces him as the Count of Monte Cristo, he is standing behind a wrought iron fence with the Roman numerals MDCCCLXXV (1875) but the movie is set in the late 1820's.
Factual errors: When the Count buys his estate house he pays for it with a wagon full of gold coins. In reality that much gold would be far too heavy for a wooden wagon to support.
Revealing mistakes: If the prisoners are fed only once a day, as Faria states, they would be emaciated and severely malnourished, especially on the meager ladle full of slop they are given.
Factual errors: When Edmond returns from Elba he is promoted to Captain of the Phareon (sic). Later, when meeting Abbe Faria in prison, he asks the priest if he would teach him to read and write. This is incongruous as a ship's Captain of the early 1800's (or for any period for that matter) would have been well educated by any standards for purposes of keeping the ship's log, maintaining manifests and bills of lading as well as being able to read a map and to navigate. Often in more than one language. No ship's owner would entrust command of his ship to an uneducated sailor.
Plot holes: In the graphic when Edmond comes back to Marseilles, it says "Three Months later", yet later in the movie Edmond indicates he's been in the Chateau d'If for 13 years and "everywhere else" for a total of 16 years (Albert's age). This would indicate that he was "smuggling" for 3 years therefore the graphic should have said "Three years later". (It may have been copied from a later graphic at the end of the movie that says "3 Months Later").
Audio/visual unsynchronized: Guy Pierce's character continues talking to James Caviezel's character about them drinking Napoleon's wine in one of the opening scenes while is mouth is full, his cheeks bulging with liquid.
