Russell T. Davies and Julie Gardner spoke to Collider to talk about the upcoming series of Torchwood. The interview has some teasers about the new series which begins filming in January for broadcast next Summer.

What can you say about Season 4 and where you’re going to take the series?

DAVIES: It’s just heartfelt, really. What I mean by that is that the central issue goes to the heart of every one of us and every family. The questions it asks will cut right beneath your everyday life of work, sleep, food and family, and goes right to the heart of who we are and why we’re here. I think we’ll challenge you and disturb you. It’s the intensity of that ambition that’s the most fascinating thing. That sounds really vague, but the moment you know the initial core concept, everything I’m saying will make sense and start to click into place in your brain. You’ll say, “Oh, right, I see where this is heading.” The questions never really stop. That’s the fun of it. A whole 10 hours is a long time for a story to roll, but there’s that much power behind it. It’s self-generating, really. It’s very exciting. It’s a proper, intelligent examination of some very big issues.

With Captain Jack left in such a dark place at the end of Children of Earth, how much will that affect him now? Has he recovered from what he went through?

DAVIES: Yeah. He’s a man who’s lived for thousands of years, and he’s seen the beginning and the end of the universe. We will deal with it properly, sensibly and intelligently, but at the same time, the most important thing is to move on, as you would want for any of your friends. If your friend had suffered through a terrible time, you don’t want to be the friend who sits there and says, “Tell us about your terrible time, all over again.” Move on, look up, start a new relationship, and look towards the horizon and the dawn. There will be a lot of that with Jack as well.

How much time will have passed?

DAVIES: Torchwood will have been off-air for two years, so I think it will feel like two years have passed. The script isn’t that specific about it, but I think that two-year gap feels right.
