Before turning to films, Irish-born Charles Irwin enjoyed a long career as a music hall and vaudeville monologist. Irwin's talking-picture debut was the appropriately titled 1928 short subject The Debonair Humorist. Two years later, he proved a dapper and agreeable master of ceremonies for Universal's big-budget Technicolor musical The King of Jazz (1930). As the 1930s wore on, his roles diminished into bits and walk-ons; he fleetingly showed up as a green-tinted "Ozite" in The Wizard of Oz (1939) and appeared as the British racetrack announcer describing the progress of "Little Johnny Jones" in Yankee Doodle Dandy (1942). Before his retirement in 1959, Charles Irwin essayed such one-scene assignments as territorial representative Andy Barnes in the first few Bomba the Jungle Boy pictures and Captain Orton in The King and I (1956).
