A former manager for Woolworths, Michael Whalen performed as a radio and vaudeville singer before entering films in 1935. For many years, Whalen was an all-purpose leading man at 20th Century Fox; perhaps his best assignment during this period was Coppy, the nominal romantic lead in John Ford's Wee Willie Winkie (1937). By the 1940s, Whalen had settled into character parts, mostly at Columbia. He was last seen onscreen in an uncredited role as a minister in Elmer Gantry (1960). Michael Whalen was the brother of New York's official "greeter" Grover Whalen.
