Revealing mistake: The film was rushed to theaters, leaving a few mistakes which Universal fixed. In the original cut, toward the end, Judi Dench's human hand is visible, complete with her wedding ring. This was fixed for the re-release.
Continuity mistake: When Ash and friends are entering the wharf, there are two people that change between shot. There is also a person who goes from having his right hand in his lap to having it scratching his head. (00:23:06)
Continuity mistake: When Dumbo is born, Medici is taking a bath. The amount of foam on his arm changes between the front and back shots.
Continuity mistake: When the movie ends and Aladdin exits the palace the passers by behind are not continuous between shots, check the woman in a salmon coloured sari, for example, who walks by twice.
Continuity mistake: At the start of the film, Eggman is chasing Sonic through the streets and there is a shot of the city skyline down a street behind Sonic as he makes a turn. The camera then cuts to inside Eggman's ship to a close up him with the city skyline still behind him, only now it's different buildings behind Eggman. (00:01:00)
Continuity mistake: When Buzz is first put on the prize board at the carnival game, Ducky and Bunny are hanging further down and Ducky is pretty much level with Buzz. Later on, they are hanging higher up and Ducky struggles to reach Buzz when trying to kick him. (00:34:22 - 00:43:00)
Other mistake: When the characters go to the Himalayas, the whole time, like for 20 mins, including the confrontation scene, they are all wearing casual, short-sleeved shirts. You can see Mr. Burnish's henchmen wearing winter clothing, while the main characters don't freeze to death. They only start getting cold after a long time.
