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.

I think that idea of being far away from the people that you love is something that everyone can relate to.

Maybe there is a sort of a sweet middle ground there, where you can do something with something with like 20 to 40 million and do something which is much more character driven, but still create a sort of visual spectacle around it. That is what I'd like to do.

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.

You know, in an ideal world, people would just be intrigued and go and see a film without knowing anything about it, because that's where you're going to have the most experience of a film, the biggest, the most revelation of a film. But at the same time, I think there are benefits of having seen a trailer where you actually look forward to seeing moments in a film knowing that they're coming up. I don't know which is better.

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.
