It's twice the terror─and twice the titillation─when two beautiful orphan sisters in 19th-century Europe are sent to live with their uncle, the leader of a witch-hunting cabal. Things get nasty after a local count falls victim to a family curse and becomes a vampire who sets his sights on the siblings. Hammer's final entry in its "Karnstein" trilogy of erotic shockers stars Peter Cushing, Damien Thomas, and Playboy centerfolds Mary and Madeleine Collinson. AKA: "The Evil Twins," "Twins of Dracula." 87 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital mono; Subtitles: English; "making of" documentary; theatrical trailer.
