I worked with Steven Spielberg on 'AI,' and his level of preparation was extraordinary. He told me there was a time at the beginning when he was a bit more spontaneous and went over budget, and it absolutely wrecked his head. When you look at the power and assuredness of his movies, it makes sense that he works out so much in advance.

You work for it. You don't have to massage it, so that it fits into the way it has to be. He's just too vigorous a writer and the dialogue is too sparking to do anything other than inhabit it and give it as much truth as you can. You just try to make it part of your DNA. That's what the challenge is, really.

I don't plan in terms of career ambitions. The only career ambition I have is to work with people who are going to bring you up and elevate your performance. They'll let you know things that you didn't know already and bring you places that you might not have gotten to otherwise.

Are there people to aspire to? Can people be strong enough to withstand all of this disillusionment? Maybe the time is right for people to emerge from the easy cynicism and try to get back to a place where we can actually believe in people and trust people to have proper motivations.

It's interesting going between small parts and then bigger roles where you carry the film. If the writing is good, and if the people involved have integrity, then you'll do it, even if it's only five minutes on screen.

We lost faith in authority in the '50s, up to a point, and we spawned a lot of anti-heroes in movies, which were refreshing and open. But at this point, with the distrust that's there and the disillusionment with leadership that is so acute, we need some kind of a focus on taking the irony out and taking the anti-hero element away.

I started hitching about the country when I was 16 or 17 years old. I found the music that was played around the country - Irish music - had a particular resonance.
