 A common motif in Hollywood's woman's films is that of the doppelgänger sisters (often played by the same actress), one good and one bad who vie for one man as Bette Davis in her double role in "A Stolen Life" (1946) and Olivia de Havilland in "The Dark Mirror" (1946).The good woman is portrayed as passive, sweet, emotional, and asexual whereas the bad woman is assertive, intelligent, and erotic.The conflict between them is resolved with the defeat of the bad woman.
