Scott, who was often compared to her Hollywood contemporary Lauren Bacall during a career sidetracked by scandal, died on Jan. 31 at Cedars-Sinai Medical Center in Los Angeles, the media reports said. The Los Angeles Times quoted a longtime friend, Mary Goodstein, as saying Scott died of congestive heart failure.
Officials at Cedars-Sinai Medical Center were not immediately available for comment.
Scott excelled in playing beautiful but duplicitous women who ensnare the disillusioned men who populated film noir, a genre of dark-themed American crime and detective movies popular during the 1940s and 1950s that reflected society's insecurities during and after World War Two.
Scott physically resembled Bacall and even appeared opposite Bacall's husband Bogart in the 1947 film noir entry "Dead Reckoning" about a military veteran who encounters her in his quest to solve his war buddy's murder.
Her other noteworthy films included "The Strange Love of Martha Ivers" (1946) with Barbara Stanwyck and Kirk Douglas; "Desert Fury" (1947) with Lancaster; "I Walk Alone" (1948) with Lancaster and Douglas; "Dark City" (1950) with Heston; "The Racket" (1951) with Robert Mitchum; and "Bad for Each Other" (1953) with Heston.
She appeared in more than 20 movies but her career never recovered after her unsuccessful $2.5 million lawsuit in 1955 against a gossip magazine called Confidential that published allegations she was a lesbian.
Her film career all but ended after she starred opposite Elvis Presley in "Loving You" (1957), the rocker's second film. Scott made only one more film appearance, alongside Michael Caine and Mickey Rooney in the 1972 comedy-thriller "Pulp."
While her fame faded with time, she was recognized as one of the most important and prolific film noir actresses.
"What you call film noir I call psychological drama," Scott once said. "It showed all these facets of human experience and conflict - that these women could be involved with their heart and yet could think with their minds."
She was born as Emma Matzo on Sept. 29, 1922, in Scranton, Pennsylvania. She later took "Elizabeth Scott" as her stage name but changed her first name to "Lizabeth" to make it more distinctive. She worked as a model and stage actress in New York City as a young woman before meeting Hollywood producer Hal Wallis and entering the movies.
Wallis cast Scott in the 1945 romance "You Came Along," which led him to use her in a succession of film noir movies.
