Query: One of the top five westerns.

A strange breed of western in that it has a mixed genre: western plus film noir. The psycological elements dominant. The main character, played by Robert Mitchum, experiences a recurring nightmare. Most of the film centers on coming to grips with the meaning behind that nightmare.Excellent photography by James Wong Howe. The musical score by Max Steiner further enhances this film.
