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.

Some people will always be disappointed.

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.

Just movies in general. It's such a wonderful business as much as you feel, you are fine tuning your craft, every movie is a completely different challenge. Every fight sequence is different. Every action set piece. I enjoy that.

There are plenty of directors who work with the same actors over and over, many more times than I have. Like I have worked with Bill Nighy more times than I have worked with Kate, but I'm not married to Bill Nighy.

It's more going back into, I've always been really interested in the MKULTRA program and some of the programs and the fact that we really tried to create an actual, I guess you could call it an energy force of yourself. And you know, there were test subjects that were killed during the process. It have a huge ordeal, this huge congressional hearing that shut the whole thing down.

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.
