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 – Siobhán 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, (known at that time as Alliance Studios) 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.
