Continuity mistake: The tiger bites the seat off the suitor's trousers, allowing the viewer to see his polka-heart boxers. When we see the tiger in the courtyard, he has a part of the same boxer shorts in his mouth. So if he bit off the seat of the trousers, shouldn't he have purple cloth in his mouth? (00:11:45)
Trivia: When the tiger kitten transforms, if you watch it frame by frame its head bears a striking resemblance to Mickey's head. There is a long standing tradition for Disney to put 'hidden Mickeys' in their movies.
Continuity mistake: Aladdin, Magic Carpet and Abu have returned to the evil throne room. Aladdin tries to grab the lamp, but is unsuccessful. Abu runs for it and is turned into a toy cymbal clanging monkey. Magic Carpet swoops down to grab the lamp a split second after Abu is transformed, yet Abu is nowhere in sight on the floor even though he was directly next to the lamp clanging his cymbals.

Continuity mistake: When the sword swallower in the marketplace has the sword resting fully in his mouth. The handle is at least as thick as a broom handle. When Abu seizes it from the sword swallower's mouth and he is shown with it in later shots confronting the pursuing guards, the handle is now the thickness of a pencil. It was obviously reduced to fit Abu's tiny hands. The change in handle thickness is very evident when Abu places the sword swallower's sword on the ground.
Continuity mistake: Abu threatens the chasing guards with the sword pulled from the sword swallower's mouth during the "One Jump" chase scene. The Head Palace Guard yells "Idiots, We've all got swords." The Head Palace Guard pulls his sword with his left hand from the belt on his right side. When they chased Aladdin past the firewalker just seconds before, we can see that the Head Palace guard was leading and was wearing his sword on his LEFT side, and should have needed to use his right hand to pull it.

Continuity mistake: As Aladdin is sinking in the ocean, he sees his turban falling as well. This turban doesn't match his earlier one: it lacks the gold brim that goes all the way around the Prince Ali hat and the fabric that hung down around Prince Ali's neck. This turban has a very wide white border, a much smaller jewel and feather, and is very round, almost like a helmet.
