This early sound western was cowboy-star Ken Maynard's second to last under his 1929-1930 contract with Universal. The studio's emphasis on bringing music to the western genre despite Maynard's rather limited vocal capabilities was not paying off at the box-office. Sound in general was increasing expenditures, and the studio was about to scrap their entire series western units altogether. Besides Ken's vigorous warbling, Son of the Caballero was an average western at best, a rather flamboyant scene where Ken defeats ten sword-wielding bad guys notwithstanding. Maynard plays a drifter returning to the homestead to seek vengeance for past misdeeds done against his beloved mother (Evelyn Sherman).
