I can’t argue with this list much at all. It’s a good list. I’m reminded again that I have yet to see 'The Great Silence...'

I agree with all you said about Anthony Mann. Though 'The Naked Spur' might be a superior film, I got to give a(nother) shout out to 'Winchester '73’, my favorite of Mann’s... It’s a more complicated story--Really an interweave of a set of stories that is masterfully told, A manhunt and with competing villains who are frenemies, indians, cavalry, and, a rarity in Westerns, with a strong female lead (Shelley Winters) who stands up to the bad guys. When Jimmy Stewart gives her a gun so that she may defend her self, he says 'There are six bullets,' and hesitates, looks down. Realizing what he is about to say, with a gentleness too rich to believe, she says to him, "I know what the last one is for."

Some other glaring omissions:

'Jeremiah Johnson.' Robert Redford, as a man trying to escape the violence of the supposedly civilized world only to have that world track him down and push him smack into the violence of another world.

'Destry Rides Again.' Marlena Dietrich and Jimmy Stewart, surrounded by a cast of electrified characters--all attempting to steal scenes from each other--in an utterly charming movie that can’t quite be typed... It’s more than a comedy, not quite anti-violence, and less than a drama, but with all heart and compassion.

'The Life And Times Of Judge Roy Bean.' Robert Altman gets so much outta Paul Newman in this movie, it’s difficult to take your eyes off of him: Had to watch it twice to see what else happened. Newman himself considered it some of his best work.

'Lonely Are The Brave' Kirk Douglas as a cowboy unable to see that, first, the world has no more use for cowboys and which leads to, secondly, his defiance against the cage of civilization he perceives as being constructed around him. His defiance becomes his undoing. With Gena Rowlands and Walter Matthau. Douglas has written that this was his personal favorite. Douglas made more than a few westerns, but another one I really like was 'A Gunfight' in which he starred alongside Johnny Cash. The movie could have been better, it was shot on a shoestring and is not particularly well directed, but the script is good, inverting some western tropes, and Douglas and Cash have that chemistry that is elusive between males.

I guess there’s some debate about whether or no 'No Country For Old Men' is a western. I consider that it is, if only because it pretty clearly deals with the themes of lawlessness vs order, in which geography plays an important part.
