The reality of space travel I think is somewhere in the middle. We will get there, it will be hard, it will take a long time, and in the end, the most extraordinary thing we will find when we get there will be ourselves.

The world may hold startling developments and shocking unknowns.

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.

Space and spacecraft and zero gravity and so forth are very difficult to render.

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.

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

I think the greatest danger of the promise of space travel is that it can lead us to be cavalier about the world we live on, if we assume we can find or make more worlds. I think in our lifetimes we surely will not, probably in the lifetimes of our great-great-grand-descendants we will not.
