LUST FOR A VAMPIRE (1971)
Starring Ralph Bates and Barbara Jeffery
Dull-as-a-doornail vampire soft-core sex movie is second in Hammer's Camilla trilogy. Camilla is a seductive lesbian vampire.
Vampires start attacking topless students at an all-girl school. You really get the sense watching these Hammer nudie cuties that this British studio was actually ashamed it was putting sex in movies. The nude scenes seem awkward, the plot is weak and there's ultimately not much to see here. Skip it, unless you're a desperate teenage boy like I was when I gleefully rented it. Even then, there are better horn-dog-driven vampire films out there.
Followed by the somewhat superior "Twins of Evil."
