Question: is the truman show based on a book

Answer: No, The Truman Show was originally a spec script by Niccol, inspired by an episode of The Twilight Zone called ``Special Service''. Unlike the finished product, it was more of a science-fiction thriller, with the story set in New York City. Scott Rudin purchased the script, and set up production at Paramount Pictures. Brian De Palma was to direct before Weir signed as director, making the film for $60 million--$20 million less than the original estimate. Niccol rewrote the script while the crew was waiting for Carrey to sign. The majority of filming took place at Seaside, Florida, a master-planned community located in the Florida Panhandle.
