Continuity mistake: At the very end there is a shot of (Dennis Miller) opening the door of a car for the lady, then cuts to the inside of the car, where her door is slammed shut, obviously by Dennis Miller, and approximately half a second after her door is shut, the passenger door opens and Dennis gets in the car. He must be able to leap over cars in a single bound.
Continuity mistake: During the battle at the bordello, the head Vampire snaps Reverend J.C.'s right hand off at the wrist, exposing the bone and leaving it hanging by the skin. This is done with a close up shot of a model hand, but all other full shots of J.C. after shows his hand is fine.
