Name at birth: Vivian Mary Hartley
Vivien Leigh didn't make many films, but she made movie history with her portrayal of Scarlett in Gone With the Wind (1939, opposite Clark Gable), winning her first Oscar. Leigh's affair and marriage to actor Laurence Olivier was just as famous as her ambitious effort to play the lead in what was then -- and maybe still is -- Hollywood's biggest event. Her appearances in film were few and far between, but she won another Oscar in 1951 for A Streetcar Named Desire (with Marlon Brando). Her marriage to Olivier ended in 196O, and Leigh's final years were spent battling manic-depression and tuberculosis.
