There are things you do for the fun of doing them or to work or to hang with certain people. But the projects that I've invested myself in and cared about most deeply have absolutely been activated by a desire to chase something that I relate to, or that I see as having the potential to speak to someone else directly.

It must be good to be in Germany and France, because I have completely forgotten what it is like to be proud of your government.

I don't tend to say it's time for one of this or that genre. Things flow to you in a strange way, and why you bump into a certain kind of thing in one moment is...it's hard to explain.

To me, Fight Club was a comedy. When [David] Fincher sent me the book and I read it, the first thing I asked him was, "This is a comedy, right?" he said, "Yeah, that's the whole point," and I said, "Okay, I'm in." I certainly wasn't imagining myself as a dramatic actor when I was running around in my underwear in that film.

Instead of telling the world what you're eating for breakfast, you can use social networking to do something that's meaningful.

Look, you've got a generation of people coming along who are going to form their own new relationship with the idea of supporting the causes that they care about or changing the world. And these people are not going to do it the way our parents do it.

When you're working on a creative thing, everyone has an idea, and they're pushing it. The first time you work with anybody, you have to get comfortable with the way another person pushes hard for what they want.
