Age of Assassins

This Japanese film is a strange blend of comedy, thriller, and gangster film. Its strangeness has a certain charm that mostly works. It's about a seemingly mild-mannered teacher who finds himself pitted against a sadistic scientist who was once in league with the Nazi's. The scientist, who happens to run an asylum, uses crazy people as assassins, and one by one sends them after his new foe. There are some very funny scenes including a pillbox being blown to hell by the Japanese artillary.
