They Still Call Me Bruce (1987)

Bruce Won arrives in America in search of an American G.I. who saved his life in the Korean War. He meets an orphan boy and together they land in a string of outrageous situations. This high-strung farce culminates when a case of mistaken identity makes a gang of thugs think Bruce is a karate master. They arrange a nationally-televised match that pits our hero against a monstrous brute, and Bruce is beaten to a bloody pulp.
