Seen it before? No.
Gary Cooper plays Marshal Will Kane, who retires to marry nagging wet blanket Grace Kelly, who is like 30 years younger than him, but whatever. But on the day of his retirement/marriage, this criminal that he helped convict has gotten out of prison on a technicality, and is headed back to town on the noon train to get revenge on Kane. Kane tries to put together a posse to defend himself, but nobody is willing to help because they all suck.
The movie is shot in real time, sort of; you can watch the clocks in the background tick closer to 12 noon. (I think they stole that idea for a Johnny Depp movie a few years ago.) (EDIT: Yep. They did.) John Wayne hated it, because he thought it was un-American, somehow? He thought it was a metaphor for the HUAC and the blacklist, which, yeah, maybe, but you really have to strain to see it that way.
Position on the list: 127
