>>35172My fav overall might have to be the Cohen Brothers' True Grit. Fantastic film. I absolutely loved Shanghai Noon when I was younger, too.
Otherwise, some Westerns that I find interesting are:
High Planes Drifter. It sticks out to me more than most. It's unusual for the time in that the protagonist is clearly a bad person - not just an outcast like in the Sergio Leone Westerns, but a genuinely unlikeable man who sexually assaults a woman early in the film (though weirdly, it is treated as a romantic moment by the score; I have a feeling it was meant to be more shocking and uncomfortable than romantic, however).
Here's two you may not have heard of: Last Man Standing, starring Bruce Willis and Last Man Standing starring Sharon Stone and Gene Hackman. Fist is kind of a gangster film set in a frontier town, can't really remember much about the second other than that Gene Hackman is an evil sheriff. It's been ages since I saw either of them, so I can't remember how good they are.
Finally, Dead Man starring Johnny Depp and directed by Jim Jarmusch. Solo guitar score, black and white. Weird, but worth seeing.
