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.

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

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.

The world may hold startling developments and shocking unknowns.

When a new writer comes onto a project, he'll make wholesale changes just to mark the territory or for greater credit.

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

I try to keep up, and the scientific perspective is always part of my creative approach.
