Help publicly. Help privately. Help make sense where sense has gone missing. Help science to solve and faith to soothe. Help, and you will abolish apathy-the void that is so quickly filled by ignorance and evil.

Now, learning how to make a movie is something you can figure out in about an afternoon. The physics of it, the marks, the lights, etc. What's hard to do is to suspend your own feelings of self consciousness. The natural actors can do that; they can become part of a characterization and learn how to maintain it.

At the end of the day it's got to be a good movie, it's got to be a funny movie, and it's got to make people think, 'Hey, I couldn't have spent my time any better.'

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.

I hope my kids understand that they're not operating in a normal world. And yet there are principles they have to adhere to that are normal - like decency, choosing between right and wrong, and honesty. That's important stuff, whether you're flying first-class or not.

We are still in the position of waking up and having a choice. Do I make the world better today somehow, or do I not bother?

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.
