I've got a lot of examples about moments where I thought something would work on film and it didn't work, but I never came to that decision with the film half shot, where I was stuck on a runaway train and couldn't jump off. On those occasions where I have admitted defeat, that this is not going to work, I haven't embarked on that project and made that movie.

I just had a crazy, wild imagination all my life, and science fiction is the greatest outlet for me.

I'd rather direct than produce. Any day. And twice on Sunday.

I think we need to take responsibility for the things we put on this planet, and also take responsibility for the things we take off the planet. We need to have limiters on how far we allow ourselves to go - ethical, moral limiters.

Even though I get older, what I do never gets old, and that's what I think keeps me hungry.

I love to go to a regular movie theater, especially when the movie is a big crowd-pleaser. It's much better watching a movie with 500 people making noise than with just a dozen.

I think the greatest thing about DVD is the quality of sound and picture; the real estate to put more extras on; and, my favorite point is it stores quietly in very subtle places in your home .
