Audio problem: (May only apply to the original VHS release.) When Scar has Zazu locked up in a cage, Zazu mentions Mufasa's name and Scar yells at him, "What did you say?" Right before Scar's actual line, whilst Zazu is talking, you hear Scar's "What did you say?" line very faintly in the background, even though Zazu has not even mentioned Mufasa yet.
Continuity mistake: When the evil king's female assistant is "turned into" Odette, and Prince Derek is dancing with her near the end, he puts the locket on her. The chain goes around her hair, and in the next shot, it's under her hair. They were dancing the whole time, so how could she or Derek have pulled her hair out of the chain?
Continuity mistake: In the scene where Aladdin is talking to Jasmine in front of the mirror the jewelled flower is in a vase with a real flower when the monkey under the table takes the real flower and the scene cuts back and shows the vase with both flowers. Seconds later the vase is completely empty.
Audio problem: About halfway through the movie, Richard and Fantasy reunite on the island. Richard says, "Fantasy." and Fantasy responds with, "Well, what were you expecting honey? The tooth fairy?" When she says "the tooth fairy" her lips are saying something completely different (and it's even worse, since it's a close-up of her face).
Continuity mistake: In the credits, Cammy has been mispelt "Cammie"
