Roll on Texas Moon was the first of 26 Roy Rogers vehicles directed by fast-action specialist William Witney. The plot concerns a deadly feud between cattle ranchers and sheepherders, with the villains playing both ends down the middle. Working on behalf of the cattlemen, Rogers tries to avoid an all-out range war, finding time to champion the cause of gorgeous sheep rancher Jill Delaney (Dale Evans). Dennis Hoey, best known for his portrayals of the thick-witted Lestrade in Universal's "Sherlock Holmes" series, is rather surprisingly cast as the main heavy. While the musical content of Roll on Texas Moon is as omniprescent as ever, the "thrill" content is considerably heightened by the expert contributions of William Witney.
