I never stopped loving the deeper sciences, and I read as deeply into lay science as I can.

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

Once you've written a good script, it will get made or not get made, according to variables you cannot control, like stars getting interested, and the superstitions in Hollywood rising or falling around what is over and done with versus what's in.

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.

For a successful writer, the secret is to have many irons in the fire. Write the next thing.

I will never probably have the mathematical foundation to truly understand what string theorists are talking about, but it feels good, just for its own sake, to get as close to an understanding as you can.

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