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 was introduced by the actor Boris Karloff. Many of the episodes were adaptations of stories by science fiction 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 series Out of the Unknown.
