An X-wing fighter flies like an airplane. If you look at the physics, it's actually quite impossible.

Now with the international space station generating a bunch of video, and Space X and other companies pursuing private space flight, I think it's on all of our radars much more than it has been since the moonshots. The science of filmmaking is making these visions possible now.

I grew up a really nerdy kid. I read science fiction and fantasy voraciously, for the first 16 years of my life. I read a lot of classic Cold War science fiction, which is much of the best science fiction, so I speak the language well, which is a commodity that's not easy to come by in Hollywood.

You need a human story to intersect those points of interest with real stakes on the line, and then things start to be fun, where you can see the ramifications, you see the impact on people's lives of big changes - like taking a man of science, like a surgeon, and robbing him of his understanding of the universe and forcing him into a newer and wider understanding.

A lot of screenwriters have a drawer of unsold scripts that they cut their teeth on. I don't have one. Everything I've written, after my first spec, I wrote on assignment. Everything I've written was work.

You don't control whether your movies get made. You can't. All you can control is whether your draft is great. So, you write your great draft, as best as you can, and then move on to the next thing.

Real vectoring in space, real orbital mechanics, is very counterintuitive, very strange, and very hard to render. It's expensive, and there's a learning curve. Some of it is about raising audience literacy to the point where they understand that.
