I'm a mad lover of sport. You cannot say a bad word to me about sports. So I know business is involved and I know it can be cynical, and, of course, I watch it, but for me it's pure.

There is still boxing, but there's just no money in it anymore. If you went around the world and asked a bunch of people under 20 years old, to name a boxer, I bet they couldn't name one. They'd be able to name a UFC fighter though. When I was younger there was Mike Tyson and we watched everything. I'm not saying its gone, or its going to go, and it could easily be ignited by another fighter, but it's just that idea that UFC is more violent, that desire for more spectacle, has captured people's attention.

You can't tackle climate change until you tackle poverty.

When I made 'Real Steel,' the director actually had the robots in the monitor, so he knew where everything was. So technically, there's been advancements. But at the end of the day, movies are about story and characters, so all the other stuff is great, but unless you have those two elements, then you've got nothing.

There comes a certain point in life when you have to stop blaming other people for how you feel or the misfortunes in your life. You can't go through life obsessing about what might have been.

I don't think many actors are the best judge of careers. I think generally we have good instincts about what we can do in terms of acting. And often they become directors, which I don't want to be.

I have two children and it's amazing how in tune they are with nature, with light, with smells, with time.
