Born Alexander Williamson, American supporting player Roy Brent had worked in carnivals and been a semi-professional baseball player when entering films as an extra and a stuntman in the 1920s, reportedly at the suggestion of comic Bobby Vernon. After appearing for more than a decade as a stuntman and stand-in (he was Spencer Tracy's double in Dante's Inferno ), Brent began earning supporting roles at Republic in 1939, mainly through his friend Robert Livingston, who starred in the company's Three Mesqueteers series. With his clipped mustache and steely gaze, the now veteran performer usually played a member of the gang but could be equally persuasive on the right side of the law. One such occasion was Blazing Guns (1943), a Trail Blazers oater from Monogram, in which he was well-cast as Leroy Mason's peaceful rancher brother and even got to romance the girl (Kay Forrester). Brent, whose screen career lasted until 1946, was also an accomplished composer.
