Why Laurence Olivier Left Vivien Leigh

In August 1960, Laurence Olivier walked away from Vivien Leigh after more than 20 years of marriage. He left for Joan Plowright, a younger actress most of the public had never heard of, and the announcement sent shockwaves through London and Hollywood alike. But the marriage had been dying in public for years. In 1953, Vivien froze mid-scene during a European tour, staring into the wings while Olivier improvised through her lines. By 1955, she stopped speaking entirely during a performance of Macbeth at Stratford-upon-Avon, and Olivier had to guide her offstage while the curtain came down early. Psychiatrists at Netherne Hospital diagnosed her with manic depression in the early 1950s, but the treatments were medieval: electroconvulsive therapy without anesthesia, experimental lithium that left her trembling and nauseous. Olivier turned down roles to manage her episodes, learning to recognize the warning signs and sitting through consultations with doctors who admitted they were guessing. In 1957, while Vivien toured Europe, Olivier began an affair with Joan Plowright during rehearsals for The Entertainer. Vivien fought to save the marriage, appearing beside him at premieres with her hand on his arm, but every attempt revealed how little control she had left. By early 1960, Olivier met with lawyers asking hypothetical questions about settlements and property division. When Vivien opened in Duel of Angels on Broadway, he flew to New York and gave her an ultimatum: commit to sustained psychiatric care or watch the marriage end. She refused full hospitalization because she had a play opening in three weeks. Within weeks, Olivier sent a typed letter to her hotel informing her he wanted a divorce. The public reaction nearly destroyed his career. Protesters held signs outside theaters, a member of Parliament suggested stripping him of his knighthood, and Joan Plowright received threats graphic enough that her mail had to be screened. Vivien collapsed during rehearsals in 1961, vanished for 48 hours, and the production folded. By 1962 she was propositioning strangers in hotel lobbies and wandering film sets at 3 AM. In 1963, her housekeeper found her unconscious on the bedroom floor, her lungs hemorrhaging from tuberculosis. Olivier sat by her hospital bed for a week, weeping in front of her, and something shifted between them. They began writing to each other, having dinners with Joan present, and Vivien sent him gifts only someone who had shared a life with him would remember. On July 7, 1967, Vivien died alone in her London flat at 53. When the news reached Olivier, he broke completely, repeating the same words for days: I killed her. Her psychiatric records showed the manic episodes increased in frequency after he left, and one psychiatrist wrote in 1963 that the divorce accelerated her decline. On his own deathbed in 1989, witnesses heard him say Vivien's name several times over his final days. Joan Plowright said years later that he carried guilt, not longing, but the public never wanted to hear that version of the story.
