Plot hole: At the end of the film Woody shows what a nice chap he is by spending the 'tainted' million dollars at a charity auction. He's just made his problems much worse - he paid his solicitor a large fee to arrange the deal, so he hasn't got a million in the bank. That cheque is going to bounce so fast it will crack the plaster on the roof of the bank, and bouncing a million dollar cheque is a serious criminal offence in the US. (There is no way enough interest could have built up to cover the difference, either).
Continuity mistake: When Gage, David, Diana, and Gage's Assistant are meeting in the room, right before Diana and Gage go off for their "agreement", Gage enters the room and is buttoning the right side of the jacket down by his pants, then in a following shot, he is buttoning the same coat button.
Continuity mistake: There's a bathroom scene in which Woody is shaving while having a conversation with Demi. He shaves the cream off the right side of his face, but the next shot shows the right side covered again.
Continuity mistake: After Diana confronts Gage about buying their property, she returns home and begins washing dishes. There is a wide shot of the kitchen sink with a stack of dishes and three patterned glasses sitting beside it. Diana picks up the three glasses and puts them in the sink. She then puts on yellow gloves in a close up shot. In the following wide shot, not only have the three patterned glasses reappeared by the sink but there are now two additional clear glasses as well.
Continuity mistake: When Woody has left Demi and lives in the garage with his dog, he is looking at old photos. He is looking at one photo. In the first shot, we see there's nothing on the back of the photo he's looking at, but then the angle changes, he turns the photo over, and there's now writing visible.
Continuity mistake: When David and Gage are playing pool, David pockets the cue ball yet Gage takes his next shot without using the cue ball.
Visible crew/equipment: When David and Diana are fighting in the kitchen, the boom mic is visible at the top of the screen.
