Being known as a writer did change the relationships I had with directors. The rap on actors is that they always want to inflate their parts. But when directors know you write screenplays and have a different view of things, you really get invited into the huddle in a much fuller way. And those collaborations end in friendships.

[Americans] can't understand that the water in our toilet is cleaner than 880 million have access to.

People do things in the names of good, and in the name of ideals, but the world isn't that simple. So they end up doing things that aren't necessarily good. Even if they think they're doing the right thing, but when viewed from a different perspective they can look barbaric and crazy.

The very first big photo shoot I ever did was with Bruce Weber. I couldn't believe this guy was taking my picture, so when he told me to get in the bathtub, I just did. It's only now, looking back, that I realise, you don't have to do everything people tell you.

All you have in the end is to look back and like the choices you've made.
