Being a good director is knowing sometimes when not to say something.

I want my weekends off and I want to put my kids to bed. Those are good reasons to want to be in 'Batman 2'.

I don't go to premieres. I don't go to parties. I don't covet the Oscar. I don't want any of that. I don't go out. I just have dinner at home every night with my kids. Being famous, that's a whole other career. And I haven't got any energy for it.

I drank for about 25 years getting over the loss of my father and I took the anger out on myself. I did a good job at beating myself up at sometimes. I don't drink anymore but my alcoholic head occasionally says different. 'Nil By Mouth' was a love letter to my father because I needed to resolve some issues in order to be able to forgive him.

That's what sets apart one actor from another, and that you can't teach. You can't give someone that. When you're working, putting a character together, or in a scene, that's where things will happen that you have to have the intuition to notice them, and to register them.

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.

But you see, I have played more good guys than I have played villains.
