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.

With Die Hard it was just something that I, you know, I grew up with those movies. I made a Die Hard movie with my friends in my backyard during high school. It was terrible.

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.'"

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.

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 love helicopters. In fact, my wife and my friends, the myth of the chopper in the sky is that Len's going to stop and look at it. I love, probably, destroying them, yes. You know, It's the big elements, the big toys, the trucks the helicopters, and things like that. You have a few tools to play with.

As society evolves, people are interested in a new take on an old beloved story.
