Blood Drinkers

 (imdb)

VAMPYRES-1975-Two lesbian lover, Fran (Marianne Morris) and Miriam (Anulka), are shot and killed by an unknown assailant. They come back as bloodthirsty vampires who pose as hitchhikers to lure unsuspecting (and horny) men into their manor. Meanwhile, a husband-and-wife artist team, John (Brian Deacon) and Harriet (Sally Faulkner) camp out near the house. Harriet is curious about the pair. Ted (Murray Brown), a guy who picks up the hitchhiking Fran and stays with her a couple of nights, finds a deep cut on his arm. He knows something isn't right but stays there anyway. Although the kill another guy they pick up, Fran lets Ted live and sucks blood from his arm a little at a time until he's too weak to leave. Harriet snoops around and discovers the pair sleeping in a dank basement during the day. There's several bloody death and lesbian scenes but in between there's a lot of not much happening. Sometimes it seems like the duo might not even be traditional vampires but violent killers who just like to drink blood. I also wonder that if they are "real vampires" they may have seen destroyed at the end....

VAMPYRES was notorious upon its release and had trouble with censors but garnered a cult following and a reexamination years later. 

Co-lead vampire Anulka was "Playmate of the Month" in May of 1973. She also appeared in LISTZOMANIA and on British TV. She's also the former daughter in law of Soupy Sales! Co- lead Morris made uncredited roles in a few other movies including CORRUPTION (1968) and IT'S NOT THE SIZE THAT COUNTS (1974)).  Jose' Ramon Larraz, from Spain, directed this in England.
