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

Real space movies have to involve zero gravity and a world without up or down.

Making the right choices on the worlds we explore is going to be our biggest challenge.

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.

Everything I learn about the world, whether it's the simple arcana of how commercial products are manufactured and designed and how they reach our shelves and where the chips come from and who does the code, to more profound things like whether or not a black hole might be penetrable as a wormhole, whether or not universes might be accessible from here, whether space can be stretched and compressed to enable faster-than-light travel without violating physical law - all of those things have tremendous story potential.

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.

Directing offers you the hope that your vision will reach the screen, unmolested and intact. Therefore, it's tantalizing to all writers.
