The version of the film that hit the screens in 1983 was a compromise between Disney's insistence on a commercial film with 'family' appeal, and Clayton's original, darker vision of the story. To reduce costs, original Editor Argyle Nelson Jr was fired, and assistant Editor Barry Gordon was promoted to replace him (resulting in the film's dual Editor credit). Gordon was given the task of re-editing the film, and at Disney's insistence, he was obliged to remove some of Clayton's completed scenes. The most prominent casualty was the pioneering computer-generated animation sequence that was to have opened the film, which depicted the empty train bearing Dark's Carnival arriving in the town and magically unfolding itself into place. The much-heralded sequence (which was discussed in detail in a 1982 edition of Cinefantastique) would have been the first significant use of the new Technology in a major Hollywood movie, but it was almost entirely deleted, and in the final cut, only one brief CGI shot was retained. Another Clayton sequence that was removed featured a giant disembodied hand that reached into the boys' room and tried to grab them - this was deleted by the studio on the grounds that the mechanical effect was not realistic enough, and it was replaced with a newly filmed sequence in which the boys' room is invaded by spiders. (In 2012, co-star Shawn Carson recalled the harrowing experience of having to film the new scene, which was entirely done using real, live spiders). Bradbury was asked to write new opening narration (read by Arthur Hill) to help clarify the story, and new special effects were inserted, including the "cloud tank" storm effects.
