Continuity mistake: As Sidney Bernstein pulls two $100 bills from his wallet and hands them to Axel he says, "Here's one, here's two. They're real crisp," so then Axel holds the two bills in his right hand and the papers in his left hand. However, in the next shot facing Axel, there are now at least four bills in Axel's right hand.

Continuity mistake: When Axel breaks open the drawer at the B.H. Shooting Club, he finds the notepad with the coordinates. When the pad is in the drawer there are five full lines of writing with a sixth short line below it, but when Axel takes the pad out of the drawer there are only four full lines of text with two more short lines below.

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?
