Here’s one I haven’t gotten yet, though it’s on the list. Hammer’s TWINS OF EVIL came along during the studio’s last gasps as a horror factory. Though they had dominated the Gothic horror market beginning in the late 50’s and all through the 60s, audiences found the studio’s wares old hat by the early 70s. Hammer tried to spice things up with more sex and flashes of nudity, but it was pretty much over by decade’s end. TWINS OF EVIL concerns twin sisters, one of them being a vampire. It’s notable mostly for it’s casting of Mary and Madeleine Collinson, who had achieved a sort of pop culture immortality for being the first twin centerfold subjects of notorious men’s rag Playboy. The film was also last in a trilogy based on literary vampires with lesbian tendencies (because drinking the blood of the living wasn’t evil enough, apparently). The first of these, THE VAMPIRE LOVERS, was a veritable classic far better than one might expect. It was probably Hammer’s best vampire picture since the early 60s. The follow-ups are much less visible. LUST FOR A VAMPIRE was reportedly a real stinker. TWINS OF EVIL, meanwhile, has had some good notices from other videonauts.
