Plot hole: When Jimmy calls Jill in order to get his bag back she is let in on the entire thing and gets to play her part in rescuing Oz and Cynthia. She asks Jimmy if he would have called if he hadn't grabbed the wrong bag to which the answer was no since his intention was to drive her away in order to protect her. Jimmy tells her to remember everything he has told her (which I'm assuming was for her role in the upcoming rescue) but since he tried to drive her away and they had not talked since their big fight when did Jimmy get an opportunity to tell Jill what to do in the first place?

When Lazlo gets up from the piano while saying "Your wife is in a safe," you can see a man's face reflected in the window to the left on the screen. It's not one of Lazlo's men, because they haven't entered the living room yet, and it can't be Oz's face, because he is sitting too far away from the window. (00:19:25)

Continuity mistake: When Lazlo's men are shooting at Jimmy's house there is a shot of Oz getting up from behind a counter and banging his head to a frying pan. We can see the pan start falling, however when it cuts no pan is seen falling. It wouldn't have fell to the ground this fast. (00:31:40)
