Anderson died on Sunday under hospice care in Burbank, her friend Betty Landess said, according to the Los Angeles Times.
Anderson was the widow of cinematographer Leon Shamroy, who collected 18 Academy Award nominations during his career and won for 'The Black Swan' (1942), 'Wilson' (1944), 'Leave Her to Heaven' (1945) and 'Cleopatra' (1963). They were married for 21 years until his death in 1974.
While attending Howard College (now Samford University) in her native Birmingham, Alabama, Anderson was discovered by director George Cukor, who was searching for an actress to play Scarlett O'Hara in the adaptation of Margaret Mitchell's Civil War epic 'Gone With the Wind' (1939).
In 'Lifeboat' (1944), Anderson played US Army nurse Alice Mackenzie opposite Tallulah Bankhead, William Bendix, Walter Slezak, John Hodiak and Hume Cronyn in the claustrophobic Hitchcock drama.
