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.

So I was drawing in a lot of the habit district in Brazil, put that together with an Asian influence, so there are a lot of different things in terms of architecture which assisted in the construction. Then every sci-fi movie I've grown up with from 'Blade Runner' to 'Aliens' and 'Star Wars.'"

I really thought the process and what I'm used to doing on film would be different. I thought that because I wouldn't have the same amount of time, I wouldn't do all of the tracks that I like to do or the lighting that it takes. And then, I got there and realized that I don't know any other way. I just do all that stuff really, really fast and under a lot of stress.

I wanted to do something that dealt with more of paranormal techniques that wasn't a horror movie. It is an action movie that deals with a special operations group. But if a Tier One team went in to take out Bin Laden today, if you had those kind of abilities, of course you would use that kind of group. And it was more going into that arena. And I wanted to make it feel more like, grounded, as if we had this ability.

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.

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

LSD caused a lot of experimenting going on. And we're thinking, 'Wait a minute, what if we've got...' I always thought, 'What if some of those experiments actually had worked?' And what if they did? We probably wouldn't know that they existed. We heard that they were shut down, but we probably wouldn't be told if they succeeded.
