Ten years after the last "X-Files" movie hit theaters, the team behind the hit sci-franchise is tossing out some tidbits about the sequel, currently scheduled for release on July 25.

The film, which has not yet been named, will mark the return of David Duchovny as Mulder and Gillian Anderson as Scully, two FBI agents who investigate the paranormal.

It is being directed by Chris Carter, creator of the series that ran on Fox from 1993 to 2002.

"I know what I want it to be, but Fox has ideas of their own," Carter said of the title. "I know what it should be."

What he and co-writer Frank Spotnitz did reveal Wednesday during the 25th annual William S. Paley Television Festival, was the trailer. It featured lots of snow, running, a large syringe and a helicopter.

The film will pick up six years after the end of the series. It's supposed to be a standalone feature removed from the alien mythology of the TV show, a throwback to the show's "monster of the week" episodes. Still, some lingering aspects from the series, like whether Scully's child will be a normal tyke, will be addressed.

"It will not be a mythology movie, but it's true to everything that's come before," said Spotnitz.
