20th Century-Fox hoped to make a film star out of Texas A&M football hero John Kimbrough, and to that end placed the gridiron hero in a brace of compact westerns. The first of these was Zane Grey's The Lone Star Ranger, previously filmed by Fox in 1931 with George O'Brien in the lead. Kimbrough plays Texas Ranger Buck Dunne, assigned to round up a gang of bank robbers. The leader of the gang turns out to be the "respectable" Judge Longstreth (Jonathan Hale), making life difficult for Dunne inasmuch as he's in love with Longstreth's niece Barbara (Sheila Ryan). Despite the herculean efforts of director John Tinling, John Kimbrough was consititutionally incapable of delivering a convincing performance in either Lone Star Ranger or its immediate followup Sundown Jim.
