The son of actress Mary Carr and actor William Carr, Thomas Carr made his film debut as an infant at Philadelphia's Selig Studios. Working in various production capacities throughout the late '20s and early '30s, Carr found time to play small parts in such films as Wings (1927), The Dawn Patrol (1930), and Hell's Angels (1937). After making his last on-camera appearance in the 1937 Three Mesquiteers Western Range Defenders, he was engaged as dialogue director at Republic Studios. It was at Republic that Carr was given his first opportunity to direct a film, opening up a career vista that would sustain him professionally for well over 20 years. Most closely associated with Westerns, Carr also proved adept at contemporary dramas like 1957's Dino. An early arrival on the filmed TV scene, Carr piloted episodes of such series as Superman, Richard Diamond, and Rawhide. His contributions to the popular Adventures of Wild Bill Hickok weekly included the creation of the comic-relief character Jingles, who of course was played by Andy Devine.
