When cowboy star Johnny Mack Brown left Universal for Monogram, he also left one last western, Arizona Trail, unfilmed. Thus it was that veteran sagebrusher Tex Ritter, originally cast in a secondary role, was promoted to the lead-his first such at a major studio in several years. Ritter and Dennis Moore play the sons of Erville Anderson, who is slickered out of his land by villainous Jack Ingram. Janet Shaw, who elsewhere on the Universal lot was playing the slatternly waitress in Hitchcock's Shadow of a Doubt, is seen as Ritter's leading lady. Arizona Trails also features comical sidekick Fuzzy Knight, who knows how to wield a six-gun when the need arises.
