Corrected entry: Mort's house is only a few yards from the lake. In a scene we can see Mort walking a long slope down from the house, to the place where he finds the two dead bodies in the car. Later in that scene, he pushes the car into the lake from a high cliff. That can't possibly be the same lake, as the surface is much lower in the landscape when the car hits the water than outside Mort's house.
Corrected entry: When Johnny Depp is talking to Ken Karsch for the first time, Ken pushes down a button on a timer and when he did that another button went up. When they show a cut of Johnny and then go back to Ken, the button that was down is now up and the button that was up is now down and it keeps repeating that whenever the camera cuts back to Ken.
Corrected entry: In the opening scene, Morton Rainey steals the key to a hotel room and jumps into his car and drives to a specific room. When he stops, he gets out of the car, and the sound of a shutting car door is heard. However, at the end of the scene when the camera pans out, the door to Mort's car is open, although he is still inside the hotel room.
Corrected entry: Throughout the movie Mort Rainey's obviously dyed-blonde hair changes. In the scene where he is going to their burnt house he just has blonde on his ends and in the scene where you first meet him his blonde hair goes almost to his roots. That is just one example. These two scenes happen a few days a part and there is no way his hair could have grown that fast.
