If another "The X-Files" movie was to be made, it will most likely see the return of the aliens to the sci-fi film. Talking to MovieWeb in the promotional effort for "" DVD version, writer/producer Frank Spotnitz states, "Yeah. I mean, if we were to make one more feature, I think we would definitely have to deal with alien colonization."
He also hints that the third movie may be the last of the series. "I would think so," he notes when asked whether "The X-Files 3" would be the final closure film. "It certainly would be designed to be the period on the sentence." Meanwhile, on the possible date the movie will come out, Spotnitz suggests late 2012 to be one of the potential release dates.
