Doctor X (1932) is a First National/Warner Bros. horror and mystery film. Based on the play originally titled The Terror (New York, February 9, 1931) by Howard W. Comstock and Allen C. Miller,[1] it was directed by Michael Curtiz and stars Lee Tracy, Fay Wray, and Lionel Atwill
　　The film was produced before the Motion Picture Production Code was enforced. Themes such as murder, rape, cannibalism and prostitution are interwoven into the story. The film was one of the last films made, along with Warners' Mystery of the Wax Museum (1933), in the two-color Technicolor process. Black and white prints were shipped to small towns and to foreign markets, while color prints were reserved for major cities.
