Surprised I haven’t seen John Wayne’s 1960 “The Alamo” on the list so far. The movie is great, but the story of how Wayne got it made and why he did is even better. The DVD has a great extra feature telling that story. The major studios wouldn’t touch it so Wayne did the entire production himself — starring, directing, and producing! All to make sure the story was told correctly.
The main problem with a top 10 list of Westerns is there were just too many good ones to narrow it down.
