I just don't think of myself as an actor much at all, so I don't lust after any particular roles.

3-D is a truly exciting possibility.

Of course, I was completely enthralled by the space program as a kid - particularly Apollo 11 - and was glued to the television like most of the world. Then I stopped thinking about it too much. I was a little disappointed that they weren't going on to Mars at the time, but I didn't think much of it. I was more interested in becoming a director at that point in my life and falling in love, things like that.

I think more and more scientists are becoming convinced that it's very likely that life forms of some kind exist all around the universe not so far from us.

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.

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

Sports always works for us more allegorically or metaphorically and that's what's fantastic about why we love them. You demonstrate the limits to which a human being can go and they keep pushing the boundaries of that.
