Murder Unincorporated (1965)

This crime comedy from Japan is a bit of a mixed bag where slapstick comedy and absurdist parody collide in a crime milieu of rival gangs and bosses. The appearance of a mysterious assassin prompts panicked bosses to adopt a "more is more" approach, hiring a whole bevy of eccentric assassins to both protect them and hunt down the enigmatic "Joe of Spades." The result is a film that is frequently amusing, occasionally funny and consistently engaging.
