The Hanging Tree (1959)

This movie should be right up there with "High Noon", "The Searchers", "The Magnificent Seven", and other classic westerns. The cinematography and fantastic outdoor location alone make it a must see. Gary Cooper plays a gun-toting frontier doctor, with a mysterious past, Maria Schell, a determined immigrant, who becomes his patient. Karl Malden, a ruthless miner, who becomes her partner. The supporting cast is excellent, including a very slender young actor by the name of George C. Scott, whose performance is compelling. This is one of Cooper's last movies, and one of his best. I'm not really sure why, but this movie has not been enjoyed as much as it should, or received the praise it deserves. If you're a fan of the genre, and you have not seen this movie, you owe it to yourself to check it out.
