Truth is, I'll never know all there is to know about you just as you will never know all there is to know about me. Humans are by nature too complicated to be understood fully. So, we can choose either to approach our fellow human beings with suspicion or to approach them with an open mind, a dash of optimism and a great deal of candour.

As a young man, even if I was going to see a play or a film by myself, I didn't feel like I was alone. There was something that was unfolding up there that brought me into it. And I recognised that. For those two hours, it made me feel like I belonged to something really good.

If I stopped having passion, I'd be done.

People ask me all the time, "What kind of father are you?" I won't know until my kids are grown.

There isn't any great mystery about me. What I do is glamorous and has an awful lot of white-hot attention placed on it. But the actual work requires the same discipline and passion as any job you love doing, be it as a very good pipe fitter or a highly creative artist.

From now on we live in a world where man has walked on the Moon. It's not a miracle; we just decided to go.

The reason most of us go to the movies is to be involved in someone else's moral dilemma.
