Revealing mistake: "Prince Ali" descends on a magic carpet surrounded by fireworks...in a hall that is roughly 20 feet high. The scene is played 'straight' and not as parody. (00:39:10)
Continuity mistake: The Genie creates a royal palace for Aladdin, who pranks him, acting unimpressed. He then cracks up and throws an arm over his shoulder. He is holding the lamp in that hand, but at the cut, he's holding it in the other hand. (00:35:20)
Continuity mistake: Aladdin hopscotches through the lava pit; he has no wand in hand when viewed from behind, but in close-ups he is firmly holding it in his left. (00:18:00)
Revealing mistake: A basket with fireworks catches fire. When the basket is flung into the air, they forgot to add the CGI for it, so it's not burning at all. But the effect is there in the second shot, when Aladdin bicycle kicks it away. (00:06:00)
