Joan Fontaine got the lead role of Tessa by a lucky chance. One day, she was having lunch at Romanoff's in Hollywood, with her husband, actor
Brian Aherne. The two had just flown in by airplane from their grape ranch in Indio, California, and Fontaine was in a leather flight suit with her hair done in pigtails. Director
Edmund Goulding walked into the restaurant, and stopped by their table to say hello to his good friend Aherne. Goulding complained that he was having trouble casting a lead actress for his next movie, "The Constant Nymph." Although he had considered
Joan Leslie, she was wrong for the part. And, Goulding explained, "Jack Warner wants a star in the lead, but she has to be consumptive, flat-chested, anemic, and fourteen!" "How about me?" said Fontaine. "Who are you?" asked Goulding, not recognizing the freckled girl in pigtails sitting next to him. "Joan Fontaine," said the actress. Goulding looked startled. "You're perfect!" Fontaine was signed for the part the next day, and later called it "the happiest motion-picture assignment of my career."
