Never burn bridges. Today's junior jerk, tomorrow's senior partner.

When I was in college, I was an English major, but I was part of this great group at Stanford called the Company. We didn't know any better, so we did it all; we did King Lear, we did Hamlet, new plays ... And we did it all in a covered wagon that we took around the Bay Area. We all put our makeup on in one cracked mirror. It was the most fun I've ever had.

I used to be terribly shy, so I was either shy or over the top, and I always had a difficult time.

One of the reasons I did this, because I wasn't really looking for another science fiction film, was that my daughter can see it. She's 9 and it's really a good film for all ages.

After I left Yale, we were all doing these mad plays off - off Broadway. And I got back to that feeling I had from college, of everyone making up in front of one cracked mirror, which is what I loved - the scrappy theater idea. I think off-off Broadway healed me, made me an actor again, and I was in so many different crazy shows.

I think that's what I really dig about science fiction these days - we've caught up to it in a way. It's no longer about people with huge brains. Now it's really much more, as Jim Cameron says, the nature of being human. What it is to be human in society. How to retain one's humanity in society.

As an actor, the second and last ones were interesting for me. Because those parts had the most change in playing someone who was both light and dark, sort of Jekyl and Hyde.
