Factual error: When breaking in at the gun club, Axel squeezes the gum foil in the door crack, and fastens it with the gum. But the gum is on the outside of the door. When he opens the door, the foil would flip a bit back, so it would not connect the magnet on the back of the door - where there is no gum.
Continuity mistake: After getting kicked out of the Playboy mansion, Axel has Dent's wallet, that he supposedly picked while he was in there. In the scene with Dent, and later Hef, after he has touched Dent, you see his hands and there is no wallet there or do you see Axel put his hands inside his coat to hide the wallet. He never picks it, so how did he get the wallet?
