You're always a little surprised when something really takes off.

When Apollo 13 appeared as an opportunity and I began to tackle that in as authentic a way as I possibly could, I really became enthralled by the philosophical side of space travel, and why we need to explore - what it means to us here on Earth - all of those things. I became a huge proponent.

3-D is a truly exciting possibility.

The sooner we become a multi-planet species, the safer the species is, and the stronger the guarantee that we're going to continue to evolve.

I think it's in our nature to try to get beyond that next horizon. I think that when we as a species are scratching that itch we're actually following an evolutionary compulsion that is wired into us. I think good things come of it. That's the philosophical side.

I've acted with all types, I've directed all types. What you want to understand as a director, is what actors have to offer. They'll get at it however they get at it. If you can understand that, you can get your work done.

I've just looked for ideas and great characters that I relate to and that I think I can offer something to the audience, and I no longer look at them as experiments or genre exercises at all.
