I created my foundation as a result of that and my website, and I try to shed some light on some very topical issues right now. The idea is to try to get people to become obviously more knowledgeable about the issue and try to get corporations and individuals to contribute to these nonprofit organizations.

I urge individuals around the world to stand up, and ask local leaders, if they haven't already, to pledge to purchase cleaner cars, build green facilities, and buy green power like wind or solar energy. Our actions may determine if we become a casualty in the war for a habitable planet for generations to come.

I'm shy, but when the time comes to be wild, I'm fun-loving, adventurous, and mysterious.

[Success] always starts with the material; it always starts with the truth and honesty of the characters that you read in the screenplay and that's rarely something that can be remedied if it's simply not there by the time you shoot the film. Thank God we had that.

And now it's your turn - the time to answer the greatest challenge of our existence on this planet is now.

I hate complaining about paparazzi, I hate complaining about being recognised, because if I ultimately didn't want to be an actor or in the public eye, I would quit doing what I do. That's not the reason I do it, but I love the work so much that it's worth it.

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.
