Audio problem: When Grumpy hits his head on the bridge we hear the sound of metal, but the bridge is made of wood. (01:08:00)
Other mistake: When the Dwarfs first leave the mine entrance, the first few animation cells seem to have been omitted, so that at first the entrance is empty and then the Dwarfs appear out of thin air.
Continuity mistake: The stick that the hag uses to try to push the rock over the cliff to the dwarfs appears out of nowhere between shots.
Continuity mistake: When Snow White falls asleep on three beds, the rabbits sleep on one more and the deer on another, making 5 beds occupied, but when the dwarves come back three more beds of animals wake up making a total of 8 beds. In a previous scene Snow White looks at the 7 beds with names, not 8!
Revealing mistake: The film contains a few animation glitches which usually only last a frame or two. These could have been fixed during the film's digital restoration, but were left in, presumably because the restorers didn't want to alter a single detail of the original animation. A prime example occurs when Snow White is leading the animals to the Dwarfs' cottage. As she approaches the door, a fawn steps in front of her, and its head completely disappears for one frame.
Continuity mistake: When the queen is transformed into a hag, there is a big wart on her left hand. This wart later disappears.
Continuity mistake: When the queen is holding the poisoned apple on a string, the knot on the stem changes between shots.
