The Ox-Bow Incident (1943) is a psychological vigilante and posse film noir western starring Henry Fonda, Anthony Quinn, Mary Beth Hughes, Dana Andrews, Harry Morgan and Marc Lawrence.
If film noir is about anything it's got to be moral failings and immoral decisions, and if the western genre is about anything it is about the rough construction of United States by means of law and order.
Many of the film noir westerns we watch deal with the construction of a legal process and the layering of the base myths of Americana, and it was fitting therefore to see this quite par hazard in its ideal double billing with My Darling Clementine (1946).
The Ox-Bow Incident (1943) is a film noir for certain, largely because of the murderous mob and their moral dilemma, after we have witnessed the moral and murderous decision making of a new American community, an area of land and an area of being in which law and order are not as codified as they could be.
