On Wednesday, Fox announced production will start Dec. 10 in Vancouver on the sequel, which reunites the show's stars, David Duchovny and Gillian Anderson. The studio also picked July 25 as the U.S. release date.
Series creator Chris Carter will direct the still-untitled film. Carter also co-wrote the screenplay with Frank Spotnitz. The duo also are producing, with Fox production vp Steve Asbell overseeing for the studio.
The studio is staying little about the film's story line. All that is being revealed is that it is a "supernatural thriller" and that the movie will take the complicated relationship between FBI agents Fox Mulder (Duchovny) and Dana Scully (Anderson) in unexpected directions as Mulder continues on his quest for the truth and Scully remains inextricably tied to her partner's pursuits.
The July 25 release date would put "X-Files" up against the Sony comedy "Step Brothers," starring Will Ferrell and John C. Reilly, and an untitled Dimension comedy staring Ice Cube from MGM.
It also would be entering the market one week after Warner Bros.' "Batman Begins" sequel "The Dark Knight," which is set for July 18.
Fox's "X-Files" ran for nine seasons, ending in 2002. The first feature film, produced by Carter and co-written with Spotnitz, grossed $187 million worldwide.
Duchovny is repped by ICM, Melanie Greene Management and attorney Peter Nelson. Carter is repped by ICM and attorneys Larry Rose and Bruce Ramer. Anderson is repped by CAA, Envision Entertainment and Finch & Partners. Spotnitz is represented by Endeavor.
