Gregory Peck is Jimmie Ringo, a man tired of his reputation as the top gun of the west. He just wants to start a new life with his wife and kid, but has to deal with three brothers out to revenge the death of their youngest brother, killed by Ringo in a duel. It also stars Karl Malden as a bartender.
It's an interesting film, almost like a play. Most of the story takes place in a saloon. There are several similarities to High Noon that came out two years later. It's building up to a gun fight in the end, it's mostly told in real time and there are close ups of clocks. Actually, Gregory Peck turned down High Noon just for that reason. Too bad maybe, since High Noon is the one film remembered as a classic, but The Gunfighter is pretty good as well.
