The Black Sleep

The Black Sleep is a 1956 independently made American black-and-white horror film, scripted by John C. Higgins (from a story by Gerald Drayson Adams) and developed for producers Aubrey Schenck and Howard W. Koch, as part of a four-picture finance-for-distribution arrangement with United Artists. The film was directed by Reginald LeBorg and stars Basil Rathbone, Lon Chaney Jr., John Carradine, Bela Lugosi (in his final film role), and Akim Tamiroff in a role originally written for Peter Lorre. Ed Wood-regular Tor Johnson appears in a supporting role. The film was released as a double feature with the British science fiction monster film The Creeping Unknown. The Black Sleep was re-released in 1962 under the title Dr. Cadman's Secret.
