A stage actor from the age of seventeen, Derrick DeMarney made his film bow in 1928, at age 21. A handsome and virile leading man in films like Forbidden Music (1936) and Hitchcock's Young and Innocent (1937), DeMarney seemed to prefer playing against type in such character roles as Disraeli in Victoria the Great (1936) and Sixty Glorious Years (1938). During his wartime service, he directed the government documentary Malta GC (1942). He went on to produce or co-produce a number of films, including the morale-boosting The Gentle Sex (1943) and the noirish thrillers Latin Quarter (1946) and She Shall Have Murder (1950). De Marney's postwar film roles included the vastly different title characters in Uncle Silas (1947) and Meet Slim Callaghan (1952). Derrick DeMarney was the brother of actor Terence De Marney (1909-71).
