Factual error: This may have been considered before drawing it this way, but it's a mistake nonetheless: When Tinkerbell shows up at the end with all the other Disney characters to watch the movie, she is back lit and silhouetted just like everyone else, and so is the pixie dust she is trailing. This is done simply to resemble a dark theater full of patrons, not to play some sort of impromptu guessing game. Her pixie dust has always been luminescent so it should not appear as a shadow against the theater screen. It'd be impossible to be silhouetted to that degree if it gives off its own light.
Audio problem: When Timon and Pumbaa awake from their first dream home by the rocks, they look up to see the animals towering and singing "I just can't wait to be king", but their mouths don't match the words of the song. They are actually out of sync by a few seconds because in the first Lion King movie the chorus was already sung at this point.
Continuity mistake: Throughout this movie, some of the characters from the first movie are given new scenes. The problem is that in these scenes they don't look very much like their first movie counterparts. The obvious example here is Nala when she's explaining the whole Simba VS Scar thing to Timon and Pumbaa - her face is not only a different shape, but she's a completely different colour.
Continuity mistake: While Simba and Scar do battle at the top of pride rock, Timon, his mother and his uncle take care of the hyenas. Banzai, Shenzi and Ed were also down there with Timon and Co. throughout the scene, while in the first movie the can be seen on top of pride rock while Scar tells Simba it is the fault of the hyenas, which subsequently leads to Scar being killed by the hyenas.

Continuity mistake: When the tower of animals collapses in the "I Just Can't Wait To Be King" sequence and all of the animals are lying in a heap, the visible sable antelope is drawn incorrectly. His white facial markings that he had in the tower and when the elephant fell on his horns are gone, and he simply has a white muzzle instead. Also, the giraffe that is the middle of the heap has no horns.
