TWINS OF EVIL (1971)

ONE USES HER BEAUTY FOR LOVE! ONE USES HER LURE FOR BLOOD! WHICH IS THE VIRGIN? WHICH IS THE VAMPIRE? 

Two beautiful orphaned identical twins, Maria and Frieda Gellhorn (Playboy centerfold models Mary and Madeleine Collinson), move to the village of Karnstein to live with their uncle Gustav Weil (played by Hammer horror favorite, Peter Cushing), a fanatical puritan and leader of the local witch-hunting “Brotherhood.” The village Count (Damien Thomas, Never Let Me Go), an evil man who secretly practices Satanism, uses black magic and transforms into a vampire. Unhappy with her new life, Frieda seeks escape and tragically falls under the spell of the Count. Now overcome with an insatiable hunger for human blood, Frieda has to hide her secret from her sister, and escape her uncle’s killing grasp!
