Continuity mistake: When Snow White, in armour, and her followers are in the Queen's chamber and they fight "nail-men", one man is seen wearing a harness on his back, so when one "nail-man" throws him over, doing a 360, he is able to complete the feat. Then, in a second, as the "nail-man" propels the man up the wall, the harness is gone.
Revealing mistake: When Snow White rides the white horse bareback to the dark wood. In the last few frames as the horse gets trapped in the mud you can see a very thin set of reins attached to the horse's head.
Continuity mistake: When Queen Ravenna steps into her "milk" bath her hair is braided around her head; when she stands up, her hair is long and falling down her back.
Continuity mistake: When the dwarves are opening the castle gates for Snow White and her army, the rope holding the counterweight is cut. We see the gate dropping a few metres before hitting the ground. The dwarves then decided to hang on the rope and be the counterweight. However, when the gate dropped a few metres, the rope would have been pulled up a corresponding distance, but it was still hanging in the original place where it was cut.
Continuity mistake: In the scene where Snow White and her army are riding towards the castle, Snow's position changes from riding in front of the column with two soldiers carrying the King's flag flanking her, to riding between William and the Count and no flags around them, and back to riding in front of everyone.
Continuity mistake: In the scene where Snow's army is riding towards the castle, there are shots from inside the castle where the dark soldiers are releasing the fireballs, and when the camera follows their trajectory, the riders can be seen straight ahead. However, there is a shot from the riders' side where they are riding alongside the castle (the castle walls and the soldiers are seen in the background) and heading to the gates in a circular path, not at all the straight one it shows when they arrive at the gates.
Continuity mistake: When Snow White is riding the white horse into the dark forest, she is riding bareback, but there is one shot where she is sitting on a tan blanket.
Continuity mistake: When Snow White is escaping from the West Tower she goes through the underground sewer and ends up at the opening 3/4 of the way up the cliff, panicking at the height. Yet when she jumps off, she only falls two feet before before hitting water.
Continuity mistake: During the scene where Queen Ravenna's men bring the huntsman to her throne room, after the shot where the Huntsman says, "and if I refuse?" Ravenna lifts her head, which is tilted slightly to the right. In the next shot, where Ravenna's men put the weapons to the huntsman, Ravenna's head is suddenly tilted to the left.
