Javier Bardem

I was emotionally and physically punched in the stomach. This is not a place where you go and deliver the lines and then you come back. It's kind of a life-changing experience. But it can't get better than this for any actor - this is like an opera.

When people said Africa would change me, I didn't understand what they meant. To see the poverty in the townships, for instance, is overwhelming. I found it heart-wrenching to see young children walking barefoot and hungry in the dirt. I'm the kind of person who wants to change the world right here and now, so I got frustrated.
