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.

Every time you want to reset your set and pull walls out and reset the lighting, you're burning up half an hour to an hour, and when you're trying to keep to a schedule, you're constantly having to reassess what's worth it and what you're going to have to give up in order to keep on schedule.

I had a real comfort with being on a set and in particular working with special effects and because of that background, it became much easier for me to base a first time feature film on a low budget cause I was sort of already knew how to do that.

One of the things I think is unique and signature about Blizzard is that whenever they do their games, and with Warcraft in particular, they take the things they love and put a twist on it. They showed that heroes can come from the most unexpected places, and as a player, you can play as a hero, on all sides.

When I said that something was going to cost a certain amount of money, I actually knew what I was talking about. The biggest problem that we were having on the financing front was people with lots of money saying "you need more money to make this film [Moon]," and us saying "no this is the first feature film we want to do it at a budget where we sort of prove ourselves at the starting end of making feature films; we can do this for $5 million." That is where the convincing part between me and Stuart came, we had to convince people with money that we could do it for that budget.

When we first made this whole idea this was going to be calling card film [Moon] and it was going to give the opportunity to make my first feature film. But it turned out a lot better, we just couldn't stop ourselves from going into it, and we are very proud that it turned into something that people wanted to see.

The beauty of science fiction is its open canvas. You can hypothesize about any element of the world. It doesn't have to be laser battles and things exploding, you can be JG Ballad and maybe just change one little thing about the real world and that becomes science fiction.
