Joan Fontaine dead at 96 Joan Fontaine has passed away at age 96. Both sisters had one of the most bitter sibling rivalries after Fontaine won Academy Awards ahead of her. The sisters, who never really got along since childhood, finally stopped speaking to each other in the mid-'70s. De Havilland, a two-time Oscar winner, is 97 and living in Paris. The two oldest surviving Oscar winners remain Luise Rainer, who will be 104 next month, and Joan Fontaine's sister. Tweets paying tribute to the star flowed after the news broke.
