CARMEL, Calif. — Academy Award-winning actress Joan Fontaine, who found stardom playing naive wives in Alfred Hitchcock’s “Suspicion” and “Rebecca” and also was featured in films by Billy Wilder, Fritz Lang and Nicholas Ray, died Sunday. She was 96.

Fontaine, the sister of fellow Oscar winner Olivia de Havilland, died in her sleep in her Carmel, Calif., home Sunday morning, said longtime friend Noel Beutel. Fontaine had been fading in recent days and died “peacefully,” Beutel said.

In her later years, Fontaine had lived quietly at her Villa Fontana estate about five miles south of Carmel, enjoying its spectacular view of wind-swept Point Lobos.

Fontaine’s pale, soft features and frightened stare made her ideal for melodrama and she was a major star for much of the 1940s. For Hitchcock, she was a prototype of the uneasy blondes played by Kim Novak in “Vertigo” and Tippi Hedren in “The Birds” and “Marnie.” The director would later say he was most impressed by Fontaine’s restraint. She would credit George Cukor, who directed her in “The Women,” for urging her to “think and feel and the rest will take care of itself.”

Fontaine appeared in more than 30 movies, including early roles in “The Women” and “Gunga Din,” the title part in “Jane Eyre” and in Max Ophuls’ historical drama “Letter from an Unknown Woman.” She was also in films directed by Wilder (“The Emperor Waltz”), Lang (“Beyond a Reasonable Doubt”) and, wised up and dangerous, in Ray’s “Born to be Bad.” She starred on Broadway in 1954 in “Tea and Sympathy” and in 1980 received an Emmy nomination for her cameo on the daytime soap “Ryan’s Hope.”

“You know, I’ve had a helluva life,” Fontaine once said. “Not just the acting part. I’ve flown in an international balloon race. I’ve piloted my own plane. I’ve ridden to the hounds. I’ve done a lot of exciting things.”

Fontaine had minor roles in several films in the 1930s, but received little attention and was without a studio contract when she was seated next to producer David O. Selznick at a dinner party near the decade’s end. She impressed him enough to be asked to audition for “Rebecca,” his first movie since “Gone With the Wind” and the American directorial debut of Hitchcock.

Just as seemingly every actress had tried out for Scarlett O’Hara, hundreds applied for the lead female role in “Rebecca,” based on Daphne du Maurier’s gothic best-seller about haunted Maxim de Winter and the dead first wife – the title character – he obsesses over. With Laurence Olivier as Maxim, Fontaine as the unsuspecting second wife and Judith Anderson as the dastardly housekeeper Mrs. Danvers, “Rebecca” won the Academy Award for best picture and got Fontaine the first of her three Oscar nominations.

“Miss Du Maurier never really convinced me any one could behave quite as the second Mrs. de Winter behaved and still be sweet, modest, attractive and alive,” The New York Times’ Frank Nugent wrote upon the film’s release.

“But Miss Fontaine does it not simply with her eyes, her mouth, her hands and her words, but with her spine. Possibly it’s unethical to criticize performances anatomically. Still we insist Miss Fontaine has the most expressive spine – and shoulders we’ve bothered to notice this season.”

“Rebecca” made her a star, but she felt as out of place off screen as her character was in the film. She remembered being treated cruelly by Olivier, who openly preferred his then-lover Vivien Leigh for the role, and being ignored by the largely British cast. Her uncertainty was reinforced by Hitchcock, who would insist that he was the only one who believed in her.

Fontaine was born Joan de Havilland in 1917 in Tokyo, where her British parents lived. Both she and her sister, born in 1916, were sickly, and their mother hoped a change of climate would improve their health when she moved the family to California in 1919 after the breakup of her marriage.
