Though in films fitfully since 1910, Shield's formal movie career didn't begin until he joined several other Abbey veterans in the cast of John Ford's Plough and the Stars (1936). He went on to appear in several other Ford films, generally cast in more introverted roles than those offered his brother. Unlike his sibling, Shields was not confined to Irish parts; he often as not played Americans, and in 1943's Dr. Renault's Secret, he was seen as a French police inspector. Never as prominent a film personality as his brother, Arthur Shields nonetheless remained a dependable second-echelon character player into the 1960s. ~ Hal Erickson, All Movie Guide
