Robert E. O'Connor on AllMovie

Boasting a colorful show-biz background as a circus and vaudeville performer, Robert Emmet O'Connor entered films in 1926. Blessed with a pudgy Irish mug that could convey both jocularity and menace, O'Connor was most often cast as cops and detectives, some of them honest and lovable, some of them corrupt and pugnacious. His roles ranged from such hefty assignments as the flustered plainclothesman Henderson in Night at the Opera (1935) to such bits as the traffic cop who is confused by Jimmy Cagney's barrage of Yiddish in Taxi! (1932). One of his most famous non-cop roles was warm-hearted bootlegger Paddy Ryan in Public Enemy. During the 1940s, O'Connor was a contract player at MGM, showing up in everything from Our Gang comedies to the live-action prologue of the Tex Avery cartoon classic Who Killed Who? (1944). Robert Emmet O'Connor's last film role was Paramount studio-guard Jonesy in Sunset Boulevard (1950). Twelve years later, he died of injuries sustained in a fire.
