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.

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

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.

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.

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.

So the question never comes up. I love to work with actors who I feel really confident in knowing what I'm going to get from them. And making a movie is such a risk that it's comforting to build up a good support team in production as well as cast.

When I started doing television, I thought that I would change the way that I shot, the way that I blocked, and the technical side of it. You're not going to change your relationship with the actors or how you approach the characters. That wasn't any different.
