And costume is so important for an actor. It absolutely helps to get into character; it's the closest thing to you, it touches you. Some actors like to go into make-up and then put their clothes on, but I like to dress first; that's my routine.

In the past, I’ve had my share of good reviews, but it’s always the crazy, scary, weirdo guy. I don’t even know how it happened. Look at me. I mean, when I’m naked, I look like a bald chicken. How did I get to be a scary bad guy?

Over the years, I have been asked to play these sort of scary frenetic characters that express their emotions physically.

I'm rarely asked to play the smartest man in the room.

I never told my father I loved him before he died, and I have a lot of issues about that. They're all swimming around in my head, in my heart, unresolved, and in a way it felt fitting to dedicate the film to him.

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.
