I think we tried to make a film [Moon] that was about human beings as opposed to going from one special effects set piece to the next one, which is what a lot of science fiction films these days do.

I really don't see CG as a goal in its own right. I really do believe it's a tool. In the advertising industry I did a fair amount of CG, so I appreciate it for the tool that it is, and I think technologically where it's at now, you really can achieve most of your visual goals with either it or a mixture of it and practical effects.

You have to be flexible enough to realize that, over the course of making a film for three and a half years, things are going to slightly change and drift, as you work out solutions to each problem as they come up.

I was doing the promotion for Moon in LA at the same time that Tony Scott was there with [The Taking of] Pelham 123. But obviously he was so concentrating on his own film that he didn't even know I was doing a feature film.

The thing is that Warcraft has so much story available to it. For the fans, there are some key stories they really want to see on screen. I won't be doing those.

And as a first time director I needed to work with someone that I felt comfortable with, and that I could get along with. It was a perfect match [with Sam Rockwell]; I am so thrilled I got to work with him. He is a really nice and incredible guy.

When I was a kid and I was being introduced to science fiction by watching movies with my Dad, Kubrick is one of those guys that we used to watch, you know, I watched Clockwork Orange at an age that was incredibly inappropriate, but he sat there with me and he explained what was going on and you know, I came to appreciate it even if I was terrified at the time.
