Although the series has been off the air now for over a decade, the influence of The X-Files is still being felt and is unlikely to go away anytime soon. The show that brought us Special Agents Fox Mulder and Dana Scully went on to become one of the most beloved science fiction shows of all time and spawned off two feature films, the second just a few years ago.
And while The X-Files: I Want to Believe wasn't exactly a runaway success, it earned enough at the box office to be profitable, which is what really matters in the long run. It shouldn't be too surprising then that a third X-Files film is supposedly in the works, according to Gillian Anderson, the actress who played Scully. According to Anderson there's been a lot of talk about a third installment, and though she's unsure of who's writing it, she has heard that something is going on with the franchise.
That's not a lot to go off of, but if there's room for profit, there's almost always room for a sequel. No telling when it would film, as Anderson has been starring in a string of smaller films and David Duchovny is filming the Showtime hit Californication, but the film, if it happens, is still in the earliest stages of development.
