At 23 it was all about acting. Today it's getting my kids to school, making sure that they've done their homework. I'm in my fifties, and I'm turning into a square.
The thing a drama school can't give you is instinct. It can sharpen instinct but that can't be taught, and you have to have intuition. It's an essential ingredient.
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.
When I decided that I might want to do acting for a living - I don't know where it really came from, since there was no school play or any of that - my mom gave me her blessing. I had to get a scholarship - that was the only way I could have gone to drama school.
