Vaudeville and stage performer Pat O'Malley was a mere lad of seventeen (or thereabouts) when he inaugurated his film career at the Edison company in 1907. A dependable "collar-ad" leading man possessed of an athlete's physique, O'Malley rose to stardom at the Kalem Studios during the teens. From 1918 to 1927, O'Malley hopscotched around Hollywood, appearing at Universal, First National, Vitagraph and Paramount; he starred in war films (Heart of Humanity [1918]), westerns (The Virginian [1922]) and adaptations of bestsellers (Brothers Under the Skin [1922]). His talkie debut in 1929's Alibi would seem to have heralded a thriving sound career, but O'Malley had aged rather suddenly, and could no longer pass as a romantic lead. He worked in some 400 films in bits and supporting roles, frequently showing up in "reunion" films in the company of his fellow silent screen veterans (Hollywood Boulevard [1936], and A Little Bit of Heaven [1941]). O'Malley remained "on call" into the early '60s for such TV shows as The Twilight Zone and such films as The Days of Wine and Roses (1962). Pat O'Malley's film credits are often confused with those of Irish comedian/dialectian J. Pat O'Malley (1901-1985) and Australian performer John P. O'Malley (1916-1959).
