Paint Your Wagon. Lee Marvin Clint Eastwood In a musical What more needs to be said? Greatest film pitch ever. More seriously, I like Rio Bravo, though there's whole bunch of politics around it's production and High Noon (which is a pretty powerful, tense and groundbreaking movie in its own right). Dean Martin in this film is the basis for Gene Wilders' character. There is a remake called El Dorado from a decade later by the same director which is inferior. Also Walter Brennan is the greatest Western character actor ever, and he really shines in this. The only blemish is how wooden Ricky Nelson is. I really like Destry Rides Again with Jimmy Stewart as a lawman who doesn't like guns. Referencong back to Blazing Saddles, if you see it, Madeline Kahn's character suddenly makes a whole lot more sense. Agree about Once Upon a Time In the West. The whole harmonica thing with Charles Bronson that was so blatantly ripped off for The Quick and the Dead is one of my all time favorite movie gimmics. Just an amazing opening scene: The only thing that bothers me about the film is the pancake makeup they used to simulate tanned skin. Tombstone had the same issue
