Vampires (1998)

Other mistake: When Daniel Baldwin carjacks the guy at the gas station (director Frank Darabont in a cameo) we can clearly see that his car is a Cadillac. However, in the end credits he is listed as "Man with Buick."

Revealing mistake: When Montoya uses a spear to toss the vampire woman from the prison door into the sunlit street, it is an obvious dummy that has been used. First you see the woman stumble out, and the first flames shoot out of her, then the angle changes to a close-up of her as she is engulfed in fire. In the close-up, she has become bigger and rounder, and does not move.

Continuity mistake: In the end Montoya fires the gun then presses it to his neck to cauterize the wound. However if you watch he never touches the gun to his neck.

Jack Crow: You ever seen a vampire?
Father Adam Guiteau: No I haven't.
Jack Crow: No? Well first of all, they're not romantic. It's not like they're a bunch of fuckin' fags hoppin' around in rented formal wear and seducing everybody in sight with cheesy Euro-trash accents, all right? Forget whatever you've seen in the movies: they don't turn into bats, crosses don't work, and garlic? You wanna try garlic? You could stand there with garlic around your neck and one of these buggers will bend you fucking over and take a walk up your estrada chocolata while he is suckin' the blood outta your neck.

Jack Crow: Padre, I'm beginning to like you... So don't make me hurt you. OK? Just tell me what you know. I'll buy you a beer and get you laid. Come on. If you don't tell me, I'm gonna have to start cutting on you.

Jack Crow: If you think that I won't kill you because your a priest, you are seriously misjudging the wrong mother fucker!
