Ian Marcus Wolfe was an American character actor with around 400 film and television credits. Until 1934, he worked in the theatre. That year, he appeared in his first film role and later television, as a character actor. His career lasted seven decades and included many films and TV series; his last screen credit was in 1990.
Wolfe made his film debut in The Barretts of Wimpole Street (1934). He appeared in many films, including Mutiny on the Bounty (1935), Alfred Hitchcock's Saboteur (1942), Julius Caesar (1953), James Dean's Rebel Without a Cause (1955) and George Lucas's THX 1138 (1971). Although he was American by birth, his experience in the theatre gave him precise diction, and he was often cast as Englishmen on screen, including a fictional commissioner of Scotland Yard in the final film in the 1939–1946 Sherlock Holmes film series, Dressed to Kill (1946).
