Bad Boy Bubby (1993) is an Australian black comedy/drama film written and directed by Rolf de Heer. Bubby became notorious for pushing the boundaries of good taste with its strong scenes featuring violence, incest and blasphemy amongst other taboo topics. In the UK it was cut for cruelty to a cat.

Bubby is a 35-year-old man who has never set foot outside his mother’s two-room slum. His buxom beast of mother tricks him to stay locked at home for thirty years, during which time she mounts and abuses him. She keeps him from the world outside, telling him that poisonous gas filled the outside air and that without a gas mask he would instantly suffocate.
