It's not just global warming, it's not just a loss of biodiversity, it's not just the pollution of our oceans and the clearing of our rainforests and all these complicated systems, The [11th Hour] movie talks about the world economy, it talks about politics, it talks about personal transformation and environmental consciousness that we need to have in this generation to implement a lot of these changes that need to occur.

I think it's a real danger, as an actor, when you try to make some statement through your career about what the business should be doing or ultimately what your image should be or how you want to be perceived. I look at every project that comes along and say, "Is this something I can sink my teeth into and can do a good job on?" That's really how I choose roles.

If you can do what you do best and be happy, you're further along in life than most people.

It's very, very rare in this business [moviemaking] where a script lands on your lap ready to go.

I didn't worry about what DeNiro thought... I went in, looked him in the eye, and got the part. I was confident, even though I'd never done anything like it before. Now I realise it was ignorant confidence-I had no idea.

You can make history, or you will be vilified by it.
