I just got off the phone with writer-producer Frank Spotnitz, who was promoting the upcoming X-Files: I Want to Believe, which comes out on DVD and Blu-ray on December 2. I also had to ask him about the possibility of a third film in this popular series. Here's what he had to say about what would likely be the last film in the series.

So, there have already been whisperings about a third film from Fox. Is there anything you can tell us about that?

Frank Spotnitz: Well, yeah. I think we'd all like to to it. The studio has not said yes or no. I think the box office, unfortunately, we got creamed in the theaters by The Dark Knight. I don't think anybody could've anticipated that was going to be such a huge, historic phenomenon. To be a dark scary movie coming out the week after The Dark Knight was not the best timing. I think there's life in the franchise still. I think these are great characters. There's a date that looms very important in X-Files mythology, which is December 2012. I think after the DVD comes out, the studio will decide whether they want to roll the dice on another X-Files feature.

Are you and Chris (Carter) already hatching up ideas for that?

Frank Spotnitz: Yeah. I mean, if we were to make one more feature, I think we would definitely have to deal with alien colonization. I honestly think that's the movie that most non-hardcore X-Files fans, as well as a lot of hardcore X-Files fans are dying to see. Obviously, I think Chris has had ideas about that from the very beginning when he dreamt up this show, 16 years ago.

So do you think if this goes through, it will be the definite, final closure film? The end of the whole series?

Frank Spotnitz: I would think so. It certainly would be designed to be the period on the sentence.
