Revealing mistake: When Anna and Hans are dancing in front of the lighthouse, we don't see the shadow of the railing or the ground they're standing on.
Revealing mistake: When Madame gets off the carriage, Frou-Frou winnies to get her attention. Madame then proceeds to feed her. Frou-Frou eats from her hand. However, if you look closely at Madame's hand, it is empty. (00:03:05)
Revealing mistake: When the Pterodactyl is flying around with the egg, its shadow isn't cast as she flies over the trees.
Revealing mistake: When the elephants are making fun of Dumbo in the train caboose, Dumbo's mother pulls a pin which causes the stall door above the other elephants to fall. When the door bounces back up, you can see that the animators forgot to draw the elephants' heads and trunks and only their bodies are visible.
Revealing mistake: The stepmother's arm disappears for a split second when she tells her daughters that there is still a chance for them to become the princess.
Revealing mistake: When we first see Max, his paws are leaning on a balustrade and become transparent. Though it may seem like it's an optical effect because they're in the shadows, the next angle shows them fully lit and opaque.
Revealing mistake: When Ratigan is sneaking up on Basil inside Big Ben, there is a shot where both characters have their backs to the camera. In this shot, there is a piece of equipment directly in front of the turning gear they are standing on. This piece of metal can be seen to flicker for a few moments.
Revealing mistake: When Flynn and Maximus are fighting to get the satchel, it flies off and gets snagged on a tree branch. But you can see it goes through the branch, and not around it.
Suggested correction: If you look closely, it is very clear that it doesn't go through the branch at all, but hangs from the side as it should.
Revealing mistake: When Ralph returns to the penthouse after destroying Vanellope's kart, he goes out onto the balcony and we can see the corner of the 'OUT OF ORDER' sign reflected on the window to Ralph's left. The piece of tape is missing in the reflection.
Revealing mistake: After the jailbreak, a number of reaction shots for which the shot background is the villagers in the speeding wagon, not only do they not "bounce" with the wagon, they are not even animated.
Revealing mistake: In the scene where Mufasa and Simba are at the very top of Pride Rock and Mufasa is explaining the kingdom to Simba, one of the hand written sequence markers on the gel print is not removed. In the shot that zooms in on Simba just after the camera pans around them, there are two frames where the number 45 appear just to the left of Simba's tail. (00:09:15)
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.
Revealing mistake: Near the end, right when "little wonders" starts, Lewis takes a moment to look at his future family, Lucille, Frannie, etc. When there's a closeup on Lewis, his memory scanner reveals a reflection of no one in the gym, except for Lewis, even though people are supposed to be standing in front of him.
Revealing mistake: When "Krebbs" the koala is discussing with his other friends in the cell. If you look closely, you can notice a blink in the outline in the "Krebbs" nose. It's a clear ink & paint mistake of the blur line.
Revealing mistake: When Gazeem is standing in front of the Cave of Wonders, he leaves no footprints in the sand.
Revealing mistake: When Alice tells the Mad Hatter how she appeared in Wonderland the hare's paw is superimposed on the teapot's handle as if the pot were flat or he was floating.
Revealing mistake: Right before Dodger walks into Georgette's room in search of Oliver, she talks to herself in the mirror. But at one point the reflection moves when she doesn't. (00:43:10)
Revealing mistake: At the start of the montage in which Frollo ransacks Paris for the gypsy girl, the shot of the three soldiers kicking down the baker's door very briefly places the more distant soldier off to the right "in front" of the closer central soldier; this is a case of incorrect animation cel layering.
