I'm rarely asked to play the smartest man in the room.
There will always be spies. We have to have them. Without them we wouldn't have got Osama bin Laden - it took us years, but it happened.
It's a shame about California, and particularly about L.A., where they've demolished so many landmarks. It's a bit of a disease there, where if anything is over 30 years old, they sort of knock it down and replace it. It's a strange town, it's this sprawling suburb, and then there's a city, the old town.
I had what AA calls 'a convincer' - which made me realize that I couldn't do it any more. I went out drinking for about 70 hours here in London. At the end I knew I was done.
We lived in a flat that you could pretty much fit in my current kitchen. No wonder people drink! I can't understand why they don't throw themselves off the balconies.
Well, I needed the work - that's the honest answer. I haven't worked for a while, a couple of years. So I thought it would be nice to get back to work and earn some money.
Your own barometer is all you have to go by, and often what makes a good director is knowing when not to say something. On occasions you can find yourself on a film set where the person who is wearing the director's hat is only trying to justify his position.
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.
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.
It's always hard when you're playing someone for a lot of people out there who are going to see the movie after reading the books. There's a communion between a reader and the writer, so people will have an idea who Sirius Black is and I might not be everyone's idea of that.
I like a cheese and pickle. Nice cheese and pickle on a real old-fashioned bread. Ploughman's lunch.
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.
My big love was the Beatles. I was more into music.
Being an actor is a good way to earn a living. And to meet fabulous people. It's great to live very comfortably. I've been lucky, I've had a lot of fun with great roles, but it is true that if I were extremely rich, I would stop and I would go to play football on a beach in the Caribbean with my children.
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.
Wanting to be a good actor is not good enough. You must want to be a great actor. You just have to have that.
Interesting things come your way but as you get older, your lifestyle changes. I don't want to travel; I don't want to be in a hotel room away from my family.
I applaud anything that can take a kid away from a PlayStation or a Gameboy. That is a miracle in itself.
How many movies do you see when you can say this director really knew what film he wanted to make? I can count them on the fingers of one hand.
I still don't have a publicist. If I'm in a film, you have an obligation to promote it, I'll do as much as I can.
