THE RATS ARE COMING! THE WEREWOLVES ARE HERE! (1972)

Originally filmed as "Curse of the Full Moon," legend has it that the "rats" of the title were added due to the box office success of WILLARD. The plot concerns the Mooneys, an English family suffering from some sort of genetic lycanthropy. The youngest daughter, Diana (Jackie Skarvellis) returns from medical school with her new husband (Ian Innes) only to have their marriage disapproved by the family. The clan includes the bed-ridden father (Douglas Phair, doing a very, very poor man's Vincent Price), the wacky middle sister (Milligan regular Hope Stansbury) who toys with man-eating rats and torments her locked up, idiotic animal brother who likes to toss chickens around the room.
