From Wikipedia, the free encyclopedia. Carl William Demarest (February 27, 1892 – December 27, 1983) was an American character actor, known for playing Uncle Charley in My Three Sons. A veteran of World War I, Demarest became a prolific film and television actor, appearing in over 140 films, beginning in 1926 and ending in the 1970s. He frequently played crusty but good-hearted roles. Demarest started in show business working in vaudeville, appearing with his wife Estelle Collette (real name Esther Zychlin) as "Demarest and Colette", then moved on to Broadway. Demarest worked regularly with director Preston Sturges, becoming part of a "stock" troupe of actors that Sturges repeatedly cast in his films. He appeared in ten films written by Sturges, eight of which were under his direction, including The Lady Eve, Sullivan's Travels and The Miracle of Morgan's Creek. Demarest was such a familiar figure at the Paramount studio that just his name was used in the movie Sunset Boulevard as a potential star for William Holden's unsold baseball screenplay.
