Best Disney movie revealing mistakes of all time
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: 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: 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: 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.
