Evils of the Night (1985)
It took some doing but I made it through "Evils of the Night" mostly because I couldn't believe what I was watching. Vampire aliens who feast on horny teenager blood employ a couple of psycho mechanics to find their victims. What might have been an ordinary bad film is pushed into the realm of "What the fuck!" thanks to the casting of John Carradine (Dracula), Julie Newmar (Catwoman) and Tina Louise (Ginger from "Gilligan's Island") as the aliens and a bunch of over-the-hill porno stars as the "kids." There were quite a few pop songs that were bad even by 80s standards and Aldo Ray couldn't remember his lines because he hadn't read the script.
