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.

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.'"

Being a fan of science fiction, I collect a lot of science fiction art work and so if you go to my house there's like a library and you just geek out on science fiction material. A lot of the colony worlds specifically are built as a melting pot of different societies, because the world is at a point where there are only two zones that are left inhabitable.

Just movies in general. It's such a wonderful business as much as you feel, you are fine tuning your craft, every movie is a completely different challenge. Every fight sequence is different. Every action set piece. I enjoy that.

Some people will always be disappointed.

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.

Science fiction is an extension of science.
