I've always wanted to make a big apocalypse movie. I love 28 Weeks Later, I think it's great but Cell is totally different. It's about people's dependence on technology, the collapse of society and watching everything fall apart. That's something I've always wanted to do, which I believe it can!

I have the infinite galaxy from '2001 as my screensaver - so if I space out while I'm writing and it goes to screensaver, I can just stare off into the stars.

You have to trust your instincts and hope the fans like what you do, but you don't gut check with the fans. If we're going to make a series, people are going to have a lot of opinions and if there's one overwhelming majority or one thing you continuously hear repeated from the fans, you certainly take that into account going into next season.

I get a little too obsessive with work.

I think in a post-9/11 world, with the images coming back from Iraq, everybody knows more and more people who are going over there... the images on the YouTube phenomenon where the violence is so immediate. Direct people need something stronger to respond to. I think that there's definitely a wave of directors - who are labelled the splat pack - who really, really care about making great scary movies.

The world is changing. Social media is a way to sell movies and to build a fan base. The truth is that you have followers because they know you are into it and you're funny and you like it. I think it's great.

When I'm filming a kill scene [as a director], I just get happier and happier as we chop up body parts.
