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.

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.

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.

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.

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.

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.

In mine, they were just trying to steal a briefcase of cocaine.* That's it. Some flour that I got out of my mom's cupboard.
