There are things which need to be shown in the trailer in order to let the audience know what kind of film it is that they're going to be expecting 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.

Every film I try and make it the way I see it in my head, and it really just depends on the script and the people I'm working with or whatever interests me at that particular time.

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.

One of the biggest changes for me on a practical level of shooting the film was having a second unit.

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.
