Technology has a great advantage in that we are capable of creating dinosaurs and show them on the screen even though they are extinct 65 million years. All of a sudden, we have a fantastic tool that is as good as dreams are.

We were very, very lucky [with Tim White filmed making historic discoveries in the East African Rift ] . In 100 years, only three skeletal remains [of early man] were ever found at this site. This was the third one, and we were right there when it happened. In fact, when I first heard they had found something, I said, "Please stop it! Don't do anything right now. Let's do it tomorrow until we have unpacked our cameras and assembled our stuff.

I'm trying to find these rare moments where you feel completely illuminated. Facts never illuminate you. The phone directory of Manhattan doesn't illuminate you, although it has factually correct entries, millions of them.

You are almost stepping outside of yourself and you see something sublime.
