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.

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.

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.

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.

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.

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.
