Millionaires' Express (1986)

Multi-genre flick (western, martial arts, comedy, adventure, etc.

) with an all-star cast about a man who returns to his home town, buys everything in sight, and tries to improve its municipal (and his personal) profits by sabotaging a train so the passengers all have to stop in his town and spend lots o' money! Throw in various subplots involving some Japanese swordsmen, some bungling bankrobbers (one of whom is the head of security), and a gang of no-goods who try to mess up the town.
