Scott died on January 31 of congestive heart failure at Cedars-Sinai Medical Center in Los Angeles, said her friend Mary Goodstein.
Scott, a sultry blonde with a smoky voice in the mold of Lauren Bacall, played nightclub singers in 1947's 'I Walk Alone' opposite Burt Lancaster and in William Dieterle's 'Dark City', a 1950 release that marked Charlton Heston's first major Hollywood role.
In 'Pitfall' (1948), she was a fashion model that married man and insurance investigator Dick Powell could not resist. And in 'Too Late for Tears' (1949), also starring Dan Duryea, Scott killed not one but two husbands.
Born as Emma Matzo in Scranton, Scott, who was of Russian Heritage, attended the Alvienne School of Drama in New York.
She worked as a model for Harper's Bazaar and in 1942 landed a role as the understudy for Tallulah Bankhead in Thornton Wilder's Broadway production of 'The Skin of Our Teeth'.
