I think that it drives from an emotional connection with everybody that pulls you through all of those events, whether it's the events or what would be more the action, or I guess the visual effects side of it. So it always starts with me from - emotionally - 'Why do you care about the people who are going through what they're going through?' Because it takes a hell of a lot to put them through that. So you better care for them when they're doing it.

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 had no intention of replacing Arnold [Schwarzenegger]. There were a few things that made me want to do the movie. They were the script which had a different direction to it, and it was a chance to do a very different Quaid.

It was Die Hard in my father's workshop. And so when that opportunity came up, the possibility of doing it, it's more the teenager in me who says that, 'I have to, of course I'm going to.' So that's the fun of reinventing, or just getting involved in things that really, actually loved as a kid growing up wanting to grow up to be a director.

Science fiction is an extension of science.
