The Sword of Truth
Originally named "Wizard's First Rule" (after the first book in "The Sword of Truth" series), the show was retitled to "Legend of the Seeker" at Goodkind's suggestion since the producers wanted to differentiate the show from the books, it would have been too restrictive for them to only include plot lines from the first book, and because this would allow them the opportunity to cover the story within all the books in the series.
