John Wayne got to kiss a score of pretty ladies on screen, but his romance with Gail Russell as Penelope, the "Angel" in this story, shows the best screen chemistry I can recall. Wayne is the "Badman" Quirt Evans meaning that he settles a lot of arguments with guns a'blazin'.
He's used to fast draws, fast women, booze, bar fights, and so on. Penelope is a gentle Quaker woman living in the wilderness of the Old West. She and her parents model their lives on the teachings of scripture, especially the "Love your neighbor" ideal. Quirt gets shot in one of his many battles with gun wielding black hat bad guys; Penelope's family takes him in and nurses him back to health; during which time Quirt and Penelope get a look at each other with the obvious chemical reaction. Her sweet and vulnerable demeanor mixes splendidly with his gruff but awkwardly gentle persona.
When Wayne's nemesis Laredo (Bruce Cabot) shows up, Wayne is faced with the conflict of adapting the peaceful ways of Penelope, or reverting to his violent shoot-first-and-ask-questions-later lifestyle. Wayne's inner conflict to change his outlook on life is illustrated well, a great performance for the Duke. This all goes on under the watchful eye of the Marshall (Harry Carey), who serves as not only a foil for Wayne constantly threatening him, but almost like a self-appointed guardian who sees Quirt's potential for good, trying to steer him toward the light. Carey's humor, and good spirit plays off Wayne perfectly.
The film builds to a brilliant finish, with Quirt forced to choose between peace or violence once and for all. One of my favorite westerns. Great cast, great story.
