We rehearsed for a bit for an Indie film, which is kind of unusual, we had a week of rehearsals before we actually shot the films so we were able to really break down the script and kind of work through all of the improvisational things that he wanted to do, so he had a chance to really feel his way through before we actually shot it and I think that helped a lot.

I think there is also a certain degree of expectation that's set up by trailers, where even if you know what's going to happen in parts of the film based on the trailer, you almost anticipate and look forward to those moments based on having seen the trailer.

Obviously, there's a big homage to Outland in Moon. I obviously had Ridley Scott's response, which was great. But Peter Hyams really loved Moon and was really enthusiastic about it. He was also enthusiastic about the fact we'd remembered Outland and had remembered it fondly. I think, for him, it was like some kind of edification that there were people out there who loved his film. So, that was a really lovely feeling.

You are spending millions and millions of dollars of other peoples money when you make a movie. You have to at least approach it in a way where you can see how you can make that money back for the people who are investing.

My biggest difference with our film and those kinds of science fiction films is that they are going from one special effect set piece to the next, what we were doing was more of a character study. And I think that is the freedom that you get by doing an Indie film. You can only really do that with a lower budget. So I understand where the conflict is between those two priorities.

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.

Life and career kind of catches up with you.
