Gozu

Gozu is a 2003 Japanese surrealist film directed by Takashi Miike and written by Sakichi Sato. Starring Hideki Sone and Show Aikawa, the film follows a yakuza enforcer dispatched to kill his unstable superior, only to lose the body and become ensnared in a succession of increasingly bizarre events in a desolate suburb of Nagoya. Shot on a low budget and originally intended for direct-to-video release, the film screened at the 2003 Cannes Film Festival, which secured its theatrical release overseas. It received mixed reviews from critics.
