Continuity mistake: Towards the end after the high priest has been "sacrificed" in Sodom, Z is talking to the crowd and as the shot changes between facing forwards and turning round to talk to O (after the first burst of rain) his hair changes from soaking wet to virtually dry depending on the view.

Continuity mistake: In the scene after Black and Cera become guards for the city of Sodom, they are told to line up in formation. Cera's character claims to not have a sword but when they are walking outside to line up you can see he has a sword in his scabbard.
Continuity mistake: In the scene at the beginning of the movie Maya casually displays her unshaven armpits, but for the rest of the movie they are shaven.
