The quintessential B-movie lawman, granite-faced, mustachioed Jack Rockwell began turning up in low-budget oaters in the late 1920s and went on to amass an impressive array of film credits that included 225 Westerns and two dozen serials, working mostly for Republic Pictures and Columbia although he was never contracted by either. The Jack Rockwell that most fans remember is a stolid, unsmiling sheriff or marshal but he could also pop up as ranchers, homesteaders, stage drivers, and the occasional henchman, always recognizable even if unbilled and awarded only a couple of words of dialogue. Born John Trowbridge, Rockwell was the brother of another busy Hollywood supporting player, Charles Trowbridge (1982-1967).
