Joan de Beauvoir de Havilland, known professionally as Joan Fontaine, was an English-American actress who is best known for her starring roles in Hollywood films during the Golden Age of Hollywood. Fontaine appeared in more than 45 films in a career that spanned five decades. She was the younger sister of actress Olivia de Havilland. Their rivalry was well-documented in the media at the height of Fontaine's career.
She began her film career in 1935, signing a contract with RKO Pictures. Fontaine received her first major role in The Man Who Found Himself (1937) and in Gunga Din (1939). Her career prospects improved greatly after her starring role in Alfred Hitchcock's Rebecca (1940), for which she received her first of three nominations for the Academy Award for Best Actress. The following year, she won that award for her role in Hitchcock's Suspicion (1941). A third nomination came with The Constant Nymph (1943).
