The Three Faces of Eve is a 1957 American CinemaScope film adaptation based on a book by psychiatrists Corbett H. Thigpen and Hervey M. Cleckley, who also helped write the screenplay. It was based on their case of Chris Costner Sizemore, also known as Eve White, a woman they suggested might suffer from dissociative identity disorder. Sizemore's identity was concealed in interviews and this film, and was not revealed to the public until 1975.
