Fitzgerald's success led her to New York and the Broadway stage in 1938. She made her American debut opposite Orson Welles in the Mercury Theatre production of "Heartbreak House". Hollywood producer Hal B. Wallis saw her in this production and subsequently signed her to a contract with Warner Bros. She had two significant successes in 1939: a role in the Bette Davis film "Dark Victory", and an Academy Award nomination for her supporting performance as Isabella Linton in William Wyler's "Wuthering Heights".
