So, for me, working with larger companies has often been very satisfying, precisely because of the ability of bringing critical mass to bear on a given effort.

Henry Kissinger once told me he was very concerned about the Internet's impact on people's ability to absorb information in a concentrated way, because we've become accustomed to looking up something, getting a snippet and being satisfied with that - as opposed to reading through and considering a weighty tome that goes into great depth.

There is a project that's underway called the interplanetary Internet. It's in operation between Earth and Mars. It's operating on the International Space Station. It's part of the spacecraft that's in orbit around the Sun that's rendezvoused with two planets.

Some people argue we should solve all the problems on Earth before going off the planet, but that's like telling Lewis and Clark to stay put until the rest of the East was settled. No way.

In my Olympic history I don't think I have achieved my potential as an athlete. That's what I want when I look back at my career. I want to be able to say I gave it my best shot.

A whole new career opened up for me when I was in 'Lord Of The Rings' and 'Star Wars.'

I tell young people, including my own kids, don't do this, it's too difficult. It's a career full of rejection, disappointment and failure. It's murderously hard on the ego. Don't become an actor.

My grandfather was wary of me being a part of the industry for various reasons, ranging from the fact that we didn't know anybody; it was an unconventional career choice, and because he felt that I needed somebody to guide me.
