Continuity mistake: Wayans reveals to Sandler that he has had a steel plate put in his head. He uses it several times during the movie as a battering ram. However, when he was shown in the hospital while recovering from the shot to the head, the scar is shown as only about an inch or two long. Also, later in the movie he doesn't even have a scar.
Continuity mistake: Towards the end of the film when Archie walks into Colton's home with Keats, he pretends to trip and then shoots the guard in the eye. However, the pool the guard falls into is to the right hand side of the man, and instead of falling straight back onto the ground, as he would normally have done with the direction in which the bullet was going, he falls back first into the pool, meaning he would have had to turn around, even though he was dead.
Other mistake: Right after the second agent gets out of the drivers side door of the car he rolls down the middle of the road. No cars in the background seem to stop or move out of the way. Also just as he is thrown watch the close up shot with Sandler in the backseat and Wayans driving, the car that would have hit the agent just keeps driving behind them the entire shot.
Revealing mistake: In the opening scene where Wayans and Sandler steal the Ferrari, the owner comes out and fires a shot at them as they speed away. If you watch the gun, the muzzle kicks up way after he fires the shot, and you can even tell the actor is doing it manually by how far the gun goes up over his head. Real guns don't kick like that.
Continuity mistake: Wayans and Sandler are attacked in their motel room, and their room is riddled from all sides with bullets flying everywhere. However, when they flee the room all the lights are still burning and the TV is still heard in the background with the porno movie playing.
