Olivier and Leigh began an affair while acting as lovers in "Fire Over England" (1937), but Olivier was still married to Esmond. During this period, Leigh read the Margaret Mitchell novel "Gone with the Wind" and instructed her American agent to recommend her to David O. Selznick, who was planning a film version. She remarked to a journalist, "I've cast myself as Scarlett O'Hara", and "The Observer" film critic C. A. Lejeune recalled a conversation of the same period in which Leigh "stunned us all" with the assertion that Olivier "won't play Rhett Butler, but I shall play Scarlett O'Hara. Wait and see."
