William Wyler, born as Wilhelm Weiller (July 1, 1902 – July 27, 1981) was a German-born American film director, producer and screenwriter. Notable works included Ben-Hur (1959), The Best Years of Our Lives (1946), and Mrs. Miniver (1942), all of which won Wyler Academy Awards for Best Director, as well as Best Picture in their respective years, making him the only director of three Best Picture winners. Wyler received his first Oscar nomination for directing Dodsworth in 1936, starring Walter Huston, Ruth Chatterton and Mary Astor, "sparking a 20-year run of almost unbroken greatness."

Film historian Ian Freer calls Wyler a "bona fide perfectionist", whose penchant for retakes and an attempt to hone every last nuance, "became the stuff of legend." His ability to direct a string of classic literary adaptations into huge box-office and critical successes made him one of "Hollywood's most bankable moviemakers" during the 1930s and 1940s and into the 60's. Other popular Wyler films include Hell's Heroes (1930), Dodsworth (1936), Jezebel (1938), Wuthering Heights (1939), The Westerner (1940), The Letter (1940), The Heiress (1949), Roman Holiday (1953), Friendly Persuasion (1956), The Big Country (1958), The Children's Hour (1961), How to Steal a Million (1966), and Funny Girl (1968).
