The second of three television opportunities for Boris Karloff to play Jonathan Brewster, the role he had created on Broadway. Fearing the impact on the box office, the stage producers would not release him for the film version and the part was played by Raymond Massey. The first aired on April 11, 1949 on The Ford Theater Hour. The third was broadcast on February 5 1962.
