(at around 27 mins) during Snow White's flight from the castle astride the horse, while passing through the village, a woman appears to be wearing either a brassiere or a bikini top or halter top beneath her flaxen blouse.
After the fight scene with Snow White and the Troll, they stare at each other for a brief minute and the troll leaves. Snow white at this point has her dress covering her shoulders clearly, when the camera angle changes showing the Huntsmen approaching her, the sleeve of her dress is half way down her arm , then again in an instant back on her shoulders.
As Snow White flees with the white horse, when she mounts (at around 27 mins), it has neither saddle nor blanket. As she rides into the swamp (at around 28 mins) the horse has a not quite white blanket over it's back. When the horse mires (at around 29 mins), the blanket is gone.
During Snow White's "call to arms" speech before the final assault on the castle, her hair is blowing in the wind during all the close up shots, yet when the crowd is seen in a distanced view, there is no evidence of any wind blowing.
When Beith beats up the guard after exiting the sewer his pickaxe is not the one he had with him the rest of the movie. Its hammer side is clearly shorter in that scene as it basically ends where the handle meets the hard head of the pickaxe and earlier scenes there is clear distance between the end of the hammer side of the hard head and the handle.
Snow White meets the White Stag and puts her left hand on the right side of his face. Change camera and we then see that hand on the left of his face, then her entire left arm is to the right of his face.
When Finn sets out in pursuit of Snow White, the film makes the point that William is the only bowman. Yet later, when Finn makes his attack on the faerie forest, the white hart is killed by an arrow. The bowman can't have been William because this would be out of character. William is working against Finn and has been shown to be kind hearted.
The "bowman" is not William, as it clearly shows a different man.
Snow White was locked up in the tower for years without contact to the outside world. It appears that, within a few days of her escape, she knows how to wear a harness, how to ride a horse, how to handle arms, and how to lead a battle army. However, if she was a princess destined to rule (in other words, to be a queen regnant, and not to be passed over for a male), then she would have been taught these things from the time she could understand the concepts or handle the equipment. By the age of 10 or 12, when she was imprisoned, her education as heir to the kingdom would have been quite far along.
If it only takes two (relatively minor) scars on the face to avoid being taken by the Evil Queen, why doesn't Snow White and other women do so?
If, more logically, it is the youthful breath she needs (as depicted when the Evil Queen sucks the youth out of Greta) then the sacrifices made by Anna and her tribe are useless.
While fleeing the castle astride the white horse, despite having mounted and later mired the steed with neither saddle, blanket, nor reins, there are several shots where snow white's posture is much too straight for a bareback rider, but a rider in a saddle and stirrups which have been digitally removed, and where Snow White's hands are positioned exactly where digitally removed reins would be as well, and (at around 28 mins) the blanket has been left a bit too clearly visible to be all that easily missed.
After Gus asks Snow White for a dance and she accepts, the actor playing Gus is clearly walking away on his knees. His awkward waddling gait is markedly different from the next shot, where he is shown walking into the dance area with a normal stride.
When in the castle sewer Call says "Six dwarfs against an army, I like those odds". Gus was dead and the blind Muir was left behind, so some have assumed he should have said "Five dwarfs". However, previous scenes have clearly stated there were eight dwarfs in the movie.
