Continuity: When Nicholas and Christine are starting to leave her appartment after Nicholas smashes the smoke detector, Christine puts on her coat, then the camera cuts to the CRS van. When the camera cuts back to her, she only has the coat on her right arm.

Continuity: When Nicholas pulls Christine out of the elevator he is standing just above it and reaching through the opening. But in the next wide shot from outside the cabin he is pulling her through the door a few meters above the cabin.

Plot hole: When Nick confronts the P.I. and yells "Why are you following me?", he looks inside the car and see the file with his picture on the front seat. The P.I. notices this and turns the file over. After Nick grabs his gun, the P.I. jumps out on the other side, raises his hands in the air and tells him somone hired him and runs off. As the P.I. runs off, Nick yells "Who hired you? Who Hired you." as he stands alone next to the car. He then waits a minute and walks off. If he really wanted to know more information, he could have taken the file that was right in front of him on the carseat. It makes no sense that he is desperate for information about the strange events that are going on, sees this file on him, and yet doesn't even pick it up or look at it.

Plot hole: Towards the end, when Nick is holding Christine hostage in the CRS cafeteria, when the waiter drops the tray and the guards start shooting, Nick & Christine take off and run along the back and out a rear door into the stairwell. He does not look back to the rest of the cafeteria. He runs straight for the door as the guards continue to shoot. Feingold is then shot while standing in line back by the food counter. When Nick is on the roof and Christine is trying to tell him its all fake, he says he saw Feingold get shot. Nick actually never saw this.

Deliberate "mistake": Every time Nicholas enters his gate at home, it it daylight and then when he drives up to the house it is night. Either he has a 300 mile property or there is something else going on. It would appear that it is deliberate as it happens many times in the film. Symbolically, Nick is leaving the world as he appears with wealth and privilege (light) and entering the real van Orton world of solitude and sadness (dark).
