Science fiction is an extension of science.

I would love to travel to the future to plot out some things so there's no more guess work.

When I started doing television, I thought that I would change the way that I shot, the way that I blocked, and the technical side of it. You're not going to change your relationship with the actors or how you approach the characters. That wasn't any different.

I'm not a crazy horror fan. At that time i wasn't really looking to do something like that. But I thought to put a twist on it to put a werewolf versus vampire... 'What's the best opponent for a werewolf?' Became the idea of vampires and what about putting those two together? And ultimately it got turned down. But we loved the idea and shopped it around.

The class warfare was in the script as well. It establishes what the world is like and what would happen if we really had two zones that were left and everybody had to survive using these two areas. What would our society to do with that set up? I wanted the state of world, in my mind, how it would actually realistically unfold. I drew that from what was in the script.

It was practically with people with strings. There was no CG involved, it was just painfully taking Collin [Farrell] and Jessica Biel and putting them upside-down, we built the set upside-down and just try to twist perspective to make it all seem like zero gravity. And it was one of the most difficult things I've ever shot.
