Continuity mistake: When Paris is offering all the other prisoners half of his hidden money for a way to escape, he lays down in his bed with his cigar in his mouth and his arms at his side. The camera angle changes to a wide shot of the holding cell and the cigar is now in his right hand near the edge of the bed.
Continuity mistake: When Paris is making friends with the guy who shot a cop in the prison yard there is no shadow on Paris' face as he is talking. As a matter of fact, the shot looks like he has a huge bright light focused on him. When the guy who shot the cop is talking it is a different time of day. You can see shadows on his face and the background light is lower.
