Vivien Leigh (born Vivian Mary Hartley, and also known as Lady Olivier after 1947; 5 November 1913 - 8 July 1967) was an English stage and film actress. She won two Academy Awards for Best Actress, for her iconic performances as Scarlett O'Hara in Gone with the Wind (1939) and Blanche DuBois in the film version of A Streetcar Named Desire (1951), a role she had also played on stage in London's West End in 1949. She also won a Tony Award for her work in the Broadway musical version of Tovarich (1963). After completing her drama school education, Leigh appeared in small roles in four films in 1935 and progressed to the role of heroine in Fire Over England (1937).

Leigh next sought the role of Blanche DuBois in the West End stage production of Tennessee Williams's A Streetcar Named Desire and was cast after Williams and the play's producer Irene Mayer Selznick saw her in The School for Scandal and Antigone; Olivier was contracted to direct. The play contained a rape scene and references to promiscuity and homosexuality, and was destined to be controversial; the media discussion about its suitability added to Leigh's anxiety. Nevertheless, she believed strongly in the importance of the work.  When the West End production of Streetcar opened in October 1949, J. B. Priestley denounced the play and Leigh's performance; and the critic Kenneth Tynan, who was to make a habit of dismissing her stage performances, commented that Leigh was badly miscast because British actors were "too well-bred to emote effectively on stage". Olivier and Leigh were chagrined that part of the commercial success of the play lay in audience members attending to see what they believed would be a salacious story, rather than the Greek tragedy that they envisioned. The play also had strong supporters, among them Noel Coward, who described Leigh as "magnificent".  After 326 performances, Leigh finished her run, and she was soon assigned to reprise her role as Blanche DuBois in the film version of the play. Her irreverent and often bawdy sense of humour allowed her to establish a rapport with Brando, but she had an initial difficulty in working with director Elia Kazan, who was displeased with the direction that Olivier had taken in shaping the character of Blanche. Kazan had favoured Jessica Tandy and later, Olivia de Havilland over Leigh, but knew she had been a success on the London stage as Blanche. He later commented that he did not hold her in high regard as an actress, believing that "she had a small talent." As work progressed, however, he became "full of admiration" for "the greatest determination to excel of any actress I've known. She'd have crawled over broken glass if she thought it would help her performance." Leigh found the role gruelling and commented to the Los Angeles Times, "I had nine months in the theatre of Blanche DuBois. Now she's in command of me." Olivier accompanied her to Hollywood where he was to co-star with Jennifer Jones in William Wyler's Carrie (1952).  Leigh's performance in A Streetcar Named Desire won glowing reviews, as well as a second Academy Award for Best Actress, a British Academy of Film and Television Arts (BAFTA) Award for Best British Actress, and a New York Film Critics Circle Award for Best Actress. Tennessee Williams commented that Leigh brought to the role "everything that I intended, and much that I had never dreamed of". Leigh herself had mixed feelings about her association with the character; in later years, she said that playing Blanche DuBois "tipped me over into madness".
