Yojimbo is a fine example of a samurai/western movie by the incomparable Akira Kurosawa. That is, it is a samurai film done in a way similar to American Westerns. The storyline concerns a rogue samurai who happens upon a crummy little town and plays two gangs of criminals off against each other. The story was co-opted for A Fistful of Dollars, Last Man Standing and Omega Doom.
