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.
