Coward's films include the romantic Brief Encounter (1946) and the patriotic In Which We Serve (1942), for which he was director (with David Lean), actor, and producer. (His patriotism took another form as well; using his reputation as a flamboyant bon vivant as a cover, Coward was employed as a British agent during World War II.) He also wrote short stories and a novel, Pomp and Circumstance (1960), performed in cabaret, made recordings, and wrote three autobiographical works, Present Indicative (1937), Middle East Diary (1945), and Future Indefinite (1954), which were collected in one volume in 1986. His play Song at Twilight (1966), an autobiographical drama about an aging homosexual writer who has had to write dishonestly about himself, initiated a revival of interest in Coward's works. He was knighted in 1970.
