The Naked Spur is the very best of the Mann/Stewart western through its particularly tight knit story about a man trying to take an outlaw with a group of men and one woman. Unfortunately for him they all have their own motivations that could lead them to betray him at any time. Stewart as usual is great, but the man who steals the show is Robert Ryan. Ryan, an ace at playing heavies, is in top form offering a great villain that actually makes you able to clearly see cracks in the performances of his villlainous predessors in the Mann westerns. Ryan is just on another level from them, and inturn makes this easily the most tense of all of them. I love the whole set up of this one, that stays in the wilderness the whole time, giving the sense of isolation even while in the open. The film gives you a real sense of all the character, intelligently keeping the character count low, to craft quite the thriller.
