Philip Ives Dunne (February 11, 1908 – June 2, 1992) was a Hollywood screenwriter, film director and producer, who worked prolifically from 1932 until 1965. He spent the majority of his career at 20th Century Fox crafting well regarded romantic and historical dramas, usually adapted from another medium. Dunne was a leading Screen Writers Guild organizer and was politically active during the "Hollywood Blacklist" episode of the 1940s-1950s. He is best known for the films How Green Was My Valley (1941), The Ghost and Mrs. Muir (1947), The Robe (1953) and The Agony and the Ecstasy (1965).
Dunne was born in New York City, the son of Chicago syndicated columnist and humorist Finley Peter Dunne and Margaret Ives (Abbott) Dunne, a champion golfer and the daughter of the Chicago Tribune's book reviewer and novelist, Mary Ives Abbott.
Although a Roman Catholic, he attended Middlesex School (1920–1925) and Harvard University (1925–1929). Immediately after graduation, he boarded a train for Hollywood. His first screenplay (uncredited) was Me and My Gal, released in 1932. His first credited screenplay was The Count of Monte Cristo, released in 1934. After working for various studios, he moved to 20th Century Fox in 1937, where he would remain for 25 years (excepting 4 years civilian war service during World War II), scripting 36 films in total and directing 10. He also produced several of his later films.
