I played football the whole time I was growing up, and through two years of college. I think it's a beautiful game in many respects, one that allows you to follow a player from boyhood through manhood.

My personal sources in the intelligence community and the military are very good. They're excellent. I have very high-up, in-depth sources.

I can't worry about the consequences of what I do; that's not my job.

Once you turn on the camera, making a movie is making a movie. I don't care if it's $9 million dollars or $50 million dollars. You have bigger toys, bigger set, actors who are better paid, but once you turn on the camera, it's director and performance, and I don't find a big difference.

No matter what I've published - and you can look it up, I've published quite a lot in science, quite a few books too - none of it's very important. All will be forgotten and in a few years time will be a few comments in eight-point type in footnotes at the bottom of the page somewhere.

The most extraordinary thing about trying to piece together the missing links in the evolutionary story is that when you do find a missing link and put it in the story, you suddenly need all these other missing links to connect to the new discovery.
