The plot's still being kept a secret - as is the title - but that didn't stop the X-Files cast, writer Frank Spotnitz, and writer/director Chris Carter from showing up at Wonder Con to talk about their much-anticipated second X-Files movie.

This is what bothers me about the X-Files movie… Why is it untitled still? It's a very hard to promote a movie when you have to keep saying the Untitled X-Files Movie.
Frank Spotnitz: "That's a very good point. The movie is untitled because… Why is the movie untitled? Because the studio hasn't given us the go-ahead to release the title."

You guys know all along what the title is going to be?
Frank Spotnitz: "We have a title. We have not been able to release. Hopefully, soon."

The title is out there.
Frank Spotnitz: "The title is out there."

What's your favorite tagline from X-Files?
Frank Spotnitz: "'I Want to Believe'."

Does that sum up your philosophy?
Frank Spotnitz: "No, it doesn't, but I think it's key to the show. What I've always loved about The X-Files is that it's fun, monsters, you can just enjoy it. But it's really about something. If you're interested, look. And 'I want to believe' is really the key to Mulder and Scully and the whole series, and that's why I like it. It's food for thought."

Is it a key to the movie, too?
Frank Spotnitz: "Yes."

The audience here at Wonder Con loved [the clips]. Did you imagine years ago that there would still be X-Files people out there still going crazy for this movie?
Frank Spotnitz: "I have to say from the very beginning I hoped the show would have a long life. And the entire time we worked on it, we really thought about not just that week's broadcast, but about making something that would stand the test of time. We grew up watching Twilight Zone and that's a show that people are still watching 40+ years after it was made, and that was our ambition all along. It's very gratifying that after six years, that people are still interested in what we're doing."

Why did it take so long?
Frank Spotnitz: "You know, the honest answer is because there was a lawsuit and it took it a while to get settled. As soon as it got settled, then everything happened very quickly."

Is this the same script from, let's say six years ago, when you guys started thinking about doing another movie?
Frank Spotnitz: "No. The x-file we thought of quite some time ago. But we really didn't deal with the heart of the story, which is about Mulder and Scully and their relationship. We really couldn't because now it's six years later and the movie really deals with where they are after all that time."

That's interesting because I know we keep hearing that there's a new way you're going with their relationship. But we've seen their relationship go so many different ways, how many ways can you take it?
Frank Spotnitz: "Yeah. Well, I mean that's nice. After six years quite a lot has happened to these people, and to us. We're different now than we were six years ago and so it wasn't hard at all to find new material. We were hungry to revisit these characters and sort of get inside their heads. It was fun to do."

And I imagine this isn't going to be the last time you guys revisit these characters, right?
Frank Spotnitz: "We'll see."

It'll all depend on how successful this one is?
Frank Spotnitz: "I think so."

But you have ideas for another movie, if it happens?
Frank Spotnitz: "You know, I've always felt The X-Files is inexhaustible. It's great characters and the believer/skeptic dynamic is very rich. And what we don't understand about the world and ourselves is endless, so I've always felt it could go on forever."

Are there any episodes you'd like to go back and get another crack at doing again? Maybe you didn't think you got it quite right or there's something you would have loved to push in a different direction?
Frank Spotnitz: "Oh sure. I mean, I feel like our ambition was so high on the show that when we hit it, we really succeeded very, very nicely. But when we missed, boy to me they really went down with a thud. There's a few every season that I felt like that. But I'll meet people all the time that one of those ones that I thought was a dud, they like, so…"
