I like working. It is where I feel useful. I have no plans to cut down. I am happy with what I do. There will be a lot more of me yet, that's for sure.

Hell of a thing when a man's got good health, plenty of money and absolutely nothing to do.

I don't mind playing older characters. I find it interesting. There are parts I couldn't have got when I was 30 years old. So, it continues to interest me in the same way that it always did.

I think that the best movies are made, not from a point of view that depends on your personal history, whether it's the color of your skin or the politics that you had or the place that you come from, but from a point of view of an understanding of human nature, an understanding of history, and an understanding of what motivates people.

When I met scientists, I found them to be as various as any other group of people.

I had never even thought about doing something that I'd never done before or proving anything.

It doesn't matter to me whether I go back to outer space or not [while acting]. The job's the same and I don't have any sort of genre preferences. I'm looking for a good story and a good character, whether earthbound or not.
