Leisurely genre mash up which works best for its mood of dark pessimism. It takes the classic western theme of a range war but the cattle gangs parallel the corrupt semi-legitimate gangsters of film noir. And it's photographed by RKO noir legend Nicholas Musuraca. This is an extraordinarily gloomy experience.
Robert Mitchum plays a laconic drifter recruited to provide muscle for Robert Preston's mob of shady cowboys seeking to defraud the government on a contract to provide beef for 'Indian' reservations... and be the fall guy. Only the stranger ultimately sides with Barbara Bel Geddes and her law abiding homesteaders.
When the two male stars get round to the inevitable fist fight, Mitchum breaks the ceiling light so they can scrap in the dark. The ambience of noir is primary. Unfortunately the narrative often drags. Robert Wise was a fine genre director, but despite a few interesting set pieces, this doesn't often engage.
And given the longueurs, Mitchum's extremely passive performance is more narcotic than hypnotic. There are periods where nothing is happening. However the set design and costumes leave an impression of realism not typical of studio era westerns. Plus the Arizona locations. But this one is mainly for fans of atmosphere.
