Growing up in a particular neighborhood, growing up in a working-class family, not having much money, all of those things fire you and can give you an edge, can give you an anger.

People have an idea that one is in control of a career, a lot more than you really are. You can engineer things to an extent. But you are at the mercy of what comes in across the desk.

And of course I've got kids of my own now, and they love me being in the Harry Potter films. I'm now part of a phenomenon. You become incredibly cool to your kids, and you get a young fan base. So you became the cool dad at school. You're suddenly hip.

Speaking very generally, I find that women are spiritually, emotionally, and often physically stronger than men.
