West of Carson City remains one of the best of Johnny Mack Brown's Universal westerns. The story takes place in a gold-rush community where the locals are taken to the cleaners by duplicitious Eastern gamblers. When it becomes obvious that the local constabulary has been "bought off" by the crooks, two-fisted cattleman Jim Bannister (Brown) swings into action. The film's highlight is an outsized fistic brawl between the hero and secondary villain Breed, played by loose-limbed comic stuntman Frank Mitchell.
