Curious Obsessions (2006)

When an old 16mm film projector shows up at their doorstep, roommates Beth and Jackie aren't quite sure what to make of its mysterious appearance. The young women quickly discover that the whirring machine is haunted: it turns on at will and projects non-stop footage of ultra-erotic stag loops from the 1960s and 70s. Soon Beth and Jackie become sexually possessed by the flickering images, which have an aphrodisiac effect upon the luscious and suddenly very curious pair.
