One thing that is very different technically is that you don't get a lot of coverage in television. Not like you do on a film. I know we don't have time for separate set-ups, so I will design a scene where I'm hiding multiple cameras within that set-up. That way, if I don't have time to do five set-ups, I can do four cameras in one set-up. It's a different kind of approach for that. For the most part, a lot of television, in a visual sense, lacks time for the atmosphere and putting you in a place.

A lot of people don't put the numbers together correctly. But Underworld, honestly, the way it came about - the real way it came about - I took a meeting with Dimension, and they were looking to do just a werewolf movie, and I wasn't too interested in doing just a werewolf movie.

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.

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.

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.'"

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.

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.
