The Dark Mirror

The Dark Mirror is a 1946 American psychological horror thriller film directed by Robert Siodmak starring Olivia de Havilland as twins and Lew Ayres as their psychiatrist. The film marks Ayres' return to motion pictures following his conscientious objection to service in World War II. De Havilland had begun to experiment with method acting at the time and insisted that everyone in the cast meet with a psychiatrist. The film anticipates producer/screenwriter Nunnally Johnson's psycho-docu-drama The Three Faces of Eve (1957). Vladimir Pozner's original story on which the film is based was nominated for an Academy Award.
