Continuity mistake: When Elliot's the basketball player, when he scores the slam-dunk and breaks the headboard, he breaks the headboard after the slam as he bounces/hangs off the headboard. But in the replay he breaks the headboard as he makes the slam and then bounces/hangs off the headboard. (00:49:10)
Continuity mistake: When the Devil is a teacher in the classroom she is erasing homework assignments off the board. In the close up shots (and maybe 1 or 2 of the far away ones) the board's partially erased. In most of the far away shots however, the board isn't erased. (01:01:50)
Continuity mistake: At the very start of the film when Elliot is holding the door open for the people and they start to rush in at a very high speed, if you look closely about halfway through you will see the same people going in like in the first half of it (Especially look for a woman in a light blue suit). The clip is just being replayed.
Continuity mistake: Elliot is given a contract in the Devil's office. In one shot the contract is hanging off of the edge of the table. But a couple shots later, when the Devil picks up an apple and walks by the table, the contract is further onto the table, in a different position. (00:21:20)
Continuity mistake: When Elliot and The Devil (Liz Hurley) are in Alison's bedroom, Liz tells Elliot that Alison is in the shower. Elliot goes to take a look, but notice the bed in the middle of the room. We see a shot of him and the bed, a shot of Liz then a shot of Elliot walking to the bathroom. So, in reality, Elliot walked through the bed to get to the bathroom, but it is back in the next shot.
Continuity mistake: When Elliot is in the Devil's office, the Devil goes over to a side cabinet, and picks up an apple. Next to the apples is a vase of roses. The position of the roses changes from when the Devil goes to pick up the apple, to the next shot, when she walks over to Elliot. (00:21:40)
Continuity mistake: When Elliot is the Colombian drug dealer and is having an argument with his wife, she throws a glass of some liquid at him but it hits the door and the liquid splashes across the door. She then throws something else at him which also hits the door, but the door is now completely dry.
