Vivien Leigh [SEP] 1951–1960: Struggle with mental illness
In January 1953, Leigh travelled to Ceylon to film "Elephant Walk" with Peter Finch. Shortly after filming commenced, she had a nervous breakdown and Paramount Pictures replaced her with Elizabeth Taylor. Olivier returned her to their home in Britain, where, between periods of incoherence, Leigh told him she was in love with Finch and had been having an affair with him. Over a period of several months, she gradually recovered. As a result of this episode, many of the Oliviers' friends learned of her problems. David Niven said she had been "quite, quite mad". Noël Coward expressed surprise in his diary that "things had been bad and getting worse since 1948 or thereabouts".
