MARY CASWELL ORR was an American actress and author whose short story The Wisdom of Eve, published in the May 1946 issue of Cosmopolitan, was the basis of the Academy Award-winning film All About Eve (1950). In 1964, Orr and her husband, director-playwright Reginald Denham, adapted the short story into a play of the same name, which was produced off-Broadway in 1979. In 1970, the hit Broadway musical Applause was based on All About Eve. Alone or with her husband, Orr wrote five books, four Broadway plays and forty television scripts.
