Revealing mistake: When the Prime Minister's aide falls out of the car, he is a dummy.
Audio problem: During the joust scene, Max turns around to have another charge at the Knight and the crowd is clapping, but there's no sound at all.
Continuity mistake: During the joust scene, several tyre marks on the ground from the motorcycles disappear from the ground.
Other mistake: The same shot of Max charging on his motorcycle is used twice in less than a minute.
Audio problem: When Max is freed from the chains and punches the biker, he misses the punch completely, but the guy falls over.

Visible crew/equipment: In the motorcycle joust sequence, when the Purple Knight falls off his bicycle, his helmet flips up and you can see it's a stunt double - the Purple Knight's beard is gone.
