Marshall died on Saturday in Los Angeles following a long battle with cancer, her daughter-in-law, Trixie Flynn, said, according to Hollywood Reporter.
Marshall was the daughter of noted British actors Herbert Marshall and Edna Best.
She made her feature film debut opposite Paul Newman and Joanne Woodward in the adaptation of William Faulkner's 'The Long, Hot Summer' (1958), but her most notable work came on Broadway.
Marshall toured nationally with Alfred Lunt and Lynn Fontanne and received a best supporting actress Tony Award nomination for playing Rusty Mayerling in Goodbye, Charlie and a New York Drama Critics Award for her work as Bonnie Dee Ponder in 'The Ponder Heart', both of which opened in 1959.
