As we realize that more and more things have global impact, I think we're going to get people increasingly wanting to get away from a purely national interest.

In a situation where many national leaders do the same thing and look out for national interests, and with an issue like global warming, you're likely to get no solution, so I think you have to have some kind of ethical trump on some of those issues.

Liberalism is, I think, resurgent. One reason is that more and more people are so painfully aware of the alternative.

I think more and more people these days go for the safe option in film making.

I really don't have a lot of interest in national politics, and it's because I'm a skeptic. I think you can accomplish a lot more locally. I don't want to spin the wheels and not get anything done.

What governments and people don't realise is that sometimes the collective interest - the international interest - is also the national interest.
