Character mistake: When McCall put his gun to his head and pulled the trigger, he's saddened that it didn't go off. Most handguns (including the one he was using), after the last round is fired, the slide locks to the rear. He would not have made the mistake of thinking it was loaded.

Other mistake: After the first race, in the scene where Lightning is rushing out on the stage thinking he is the winner, loads of confetti is shot out when the King and Chick Hicks gets onto the stage. The confetti is then falling down, but not a single flake hits any of the cars. However, in the following shots, you can see plenty of it on the stage underneath the cars, even though they haven't moved.

Continuity mistake: During the street chase in Brazil, the time of day changes from night, to perhaps late afternoon/evening, to night again.

Continuity mistake: During the "Why Should I Worry" song, Dodger goes with his "scarf" of sausages through a basin full of wet cement. Logically the cement should be stuck on the sausages, though that does not appear to happen, even though the sausages went through the cement. There is cement on his paws, though, that he needs to wash off.

The Grinch: Those Whos are hard to frazzle, Max. But, we did our worst, and that's all that matters.

Continuity mistake: Darth Maul's neck is black, but when he is talking to Darth Sidious on Coruscant, his neck is flesh-toned. (00:38:45)
