Director: Dan Curtis, Cast: Karen Black, Oliver Reed, Bette Davis, Burgess Meredith

Karen Black (the greatest actress of all time) and Oliver Reed rent a spooky old house from two nutcases who leave their weird old mother in the attic and forget to mention the killer swimming pool. Once moved in, everyone has a bad acting competition, which Bette Davis wins, thanks to the best heart attack acting ever. The climax is hilarious.
