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.
Chip of the Flying U was Johnny Mack Brown's first western entry for 1940. Brown essays the title role of Chip Bennett, foreman of the Flying U ranch. Before the second reel has tumbled over the spools, Chip finds himself falsely accused of robbery and murder.

Rest assured that Chip makes short work of these bush-league Storm Troopers before the sun sets in the West. Musical interludes are provided by a group calling themselves the Texas Rangers, even though they actually hailed from Kansas City.
