Trivia: The film had a notoriously troubled production, with several writers and directors dropping out of the project during development. With a looming release date, sets were built and a crew was assembled before a script was even settled on, and the final draft had to be written around the sets that had already been built. David Fincher, then a popular music video and commercial director, was chosen to helm the film, but he had nonstop creative difficulties with the producers and studios. He has since gone on to disown the film, as he feels it isn't reflective of his vision.
Trivia: This was initially advertised as a Stephen King movie; however, King soon sued the filmmakers and demanded his name be taken off the film since, apart from the title, it bears virtually no resemblance to the short story he had written years before.
