Year One (2009)

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.

Zed: You could be my right-hand man.
Oh: I've seen what you do with your right hand. No, thank you.
