William Delgrange is known for Dortoir des grandes (1984).

A stocky, serious-looking character, Carl William Demarest started off in vaudeville in 1905 along with two older brothers. At one time he also performed in a stage act with his wife Estelle Collette (billed as 'Demarest and Collette') and then moved on to Broadway. He entered movies in 1926 and first appeared in Vitaphone one-reelers and in films for Warner Brothers, which included the first sound picture, The Jazz Singer (1927). In his later years, he became a household name on TV as retired sea captain Uncle Charley, replacing a seriously ill William Frawley in My Three Sons (1960). However, Demarest was truly at his best during the 1940s as a member of Preston Sturges's unofficial stock company of players, noted for his trademark deadpan or exasperated expressions. He made his reputation in eccentric comic supporting roles, invariably seen as pushy, wary or droll cops, business guys or wisecracking, jaundiced friends of the hero with names like Mugsy, Kockenlocker or Heffelfinger. The Great McGinty (1940), Sullivan's Travels (1941) and The Miracle of Morgan's Creek (1944) are often cited as his best films. When movie offers began to diminish, Demarest segued into television work with many guest spots and a regular co-starring role as a ranch foreman in the western series Tales of Wells Fargo (1957). As a character actor, his quiet intensity and comic timing kept him in demand well into his eighties. Nominated just once for an Oscar as Best Supporting Actor in the biopic The Jolson Story (1946), he lost out to Harold Russell for his performance in The Best Years of Our Lives (1946).

William Denjoy is known for Heval (2021).

William Derl-Davis is known for The Last Affair (1976) and A Labor of Love (1976).

Born in the upstate New York town of Horseheads in 1878, William Desmond began his show business career in vaudeville and on the stage. He had his own theatrical company by the time he made his film debut in Kilmeny (1915). Starting out in dramatic parts, Desmond soon switched to westerns and action serials, and became a major western star. When the sound era began Desmond was almost 50 years old, and was soon relegated to supporting roles. He continued making films into the 1940s.

William Devane, the movie and television actor, was born in Albany, New York, the son of Joseph Devane, who served as Franklin D. Roosevelt's chauffeur when he was Governor of New York. After graduating from New York City's American Academy of Dramatic Arts, he appeared on-stage. He finally made his Broadway debut in "The Watering Place" with Shirley Knight, a flop that lasted but one performance. (He was more successful with "The Chinese and Dr. Fish" during the 1970 season, which lasted three weeks. His sole Broadway directorial effort, the Vietnam War drama "G. R. Point," lasted for 32 performances in 1979 and brought Michael Jeter a 1979 Theatre World Award.) He made his movie debut as a revolutionary in the independently produced In the Country (1967) and began appearing on series TV. He had a small but memorable part as the lawyer committed to free-enterprise in Robert Altman's masterpiece McCabe & Mrs. Miller (1971) in 1971, but what made his reputation was his turn as President John F. Kennedy in the The Missiles of October (1974), a 1973 telefilm about the Cuban Missile Crisis. He made a bid for stardom with major roles in Alfred Hitchcock's Family Plot (1976) and John Schlesinger's Marathon Man (1976) (both 1976) and The Bad News Bears in Breaking Training (1977) (1977), as well as roles in Schlesinger's Yanks (1979) and the TV adaptation of James Jones' classic barracks drama From Here to Eternity (1979). However, any chances for a successful movie career essentially were doomed by the monumental failure of Schlesinger's comedy Honky Tonk Freeway (1981), one of the great flops its time, bringing in only $2 million at the box office against a $24 million budget. Devane moved over to nighttime series TV, playing the cad Greg Sumner on the night-time soap opera Knots Landing (1979) for 10 years. Because of his resemblance to President Kennedy and his ability to master a Kennedyesque Boston accent, Devane continues to be in demand as politicians, including presidents, in such shows as The West Wing (1999), 24 (2001), and Stargate SG-1 (1997).
