Library Film: Rod Serling's introduction to the attraction, as viewed on film in the Library, was taken in part from an episode of the series titled, "It's a Good Life." This episode told the story of a little boy who could use his mind to change things. Serling began the episode with the words, "Tonight's story on The Twilight Zone® is somewhat unique and calls for a different kind of introduction. This, as you may recognize, is a . . ." Imagineers completed that introduction with new dialogue customized for the attraction. For continuity, Serling's own voice was overdubbed by asound-alike actor to blend with the newly-added narration.
