I've worked really hard to build up a career on my own. I turned 30 recently and it took me a long time to get the chance to make a feature film and do it on my own terms.

Everyone wants to know what you want to work on and everyone wants to pitch you what they're working on. And that's just part of the process. And hopefully, at some point you find someone of like minds and you make a film.

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.

I think I was brought up with games and I don't think that they're just Pac-Man or Space Invaders. I think we've moved on, I think that there are stories being told and worlds being explored.

I think that I would like to have that kind of a budget [hundreds millions dollars] and I think the reasons for it are it gives you more time and it gives you the opportunity to be more ambitious with what you want to do with the camera and also how a scene works. I wouldn't want to direct those kinds of scripts.

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.

The films that I loved growing up were the science fiction films from the late seventies and early eighties [films], which were more about the people and how they are affected by the environments that they are in. Whether they are sort of futuristic or alien of whatever they are; that was the science fiction that I loved. So that is what we tried to make, the sort of film that felt like those old films.
