The Blood Drinkers (1964)

This weird, chilling tale of vampires and the undead seeking to bring their kind back to life features the evil Marco (Ronald Remy), an updated version of the vampiric Count Dracula, complete with cape, fangs, and clean-shaven head. Marco seeks to reanimate his long-lost love and infuse her with his victims' blood as he casts his evil spell over the inhabitants of a lonely village. Sharp fangs gleam in the night as bloodsuckers and bats seek fresh blood from their victims' veins in this eerie drive-in favorite, also known as "The Vampire People" and featuring unusual color photography and tinting effects.
