X-Files: I Want to Believe is the second feature film based on the TV series The X-Files, following the 1998 film of the same name. The sequel is directed by the TV series creator Chris Carter and written by Carter and Frank Spotnitz. The film was first anticipated in November 2001 to follow the conclusion of the ninth season of the TV series, but it remained in development hell for six years before entering production in December 2007 in Vancouver. The stars of the TV series, David Duchovny and Gillian Anderson, return to reprise their roles as Fox Mulder and Dana Scully. The premise of the film is not yet publicly known, but many of those involved, including Carter, Duchovny, and 20th Century Fox, have spoken of the film as one that would stand alone and be apart from the mythology of the TV series. The film is currently scheduled to be released on July 25, 2008.
