Out of This World is a British science fiction anthology television series made by ABC Television and broadcast in 1962. A spin-off from the popular anthology series Armchair Theatre, each episode is introduced by actor Boris Karloff. Many episodes are adaptations of stories by sci-fi writers including Isaac Asimov, Philip K. Dick and Clifford D. Simak. The series is generally seen as a precursor to the BBC science fiction anthology Out of the Unknown.
