Daughter of Darkness is a 1948 British film, with macabre overtones, directed by Lance Comfort and starring Anne Crawford, Maxwell Reed and - in the central role - Siobhan McKenna. Released in January 1948, it was based on a then ten-year-old play by Max Catto called They Walk Alone. An expensive film for its day, it was shot at Riverside Studios, Hammersmith, London, and on location. McKenna was offered a Hollywood contract following her memorable performance, but heeded the counsel of Laurence Olivier to remain in theatre work.
