I'm not the best audience for that because I'm not a great science-fiction fan. I just never got off on space ships and space costumes, things like that.

What's fascinating is that when you write a script, it's almost a stream of consciousness. You have an idea that it means something, but you're not always sure what. Then when you get on the set, the actors teach you.

My big love was the Beatles. I was more into music.

If one could have a wish, or an alternative life, I would've liked to have been John Lennon.

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.

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.

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.

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.

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.

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

I had a guitar when I was 6 or 7, a plastic guitar with the Beatles' faces on it. It would be a collector's item now. It would fetch a hefty sum, I imagine.

I have three kids who like Harry Potter so I was sort of aware of it. You can't really move from it: it's on buses, in stores, it's everywhere. One of my kids has read the books; the other two are too small but they like the movies.

I applaud anything that can take a kid away from a PlayStation or a Gameboy - that is a miracle in itself.

I got obsessed with classical music, I got obsessed with Chopin, with playing the piano.

I hadn't worked for a couple of years so I thought it would be nice to earn some money and pay the bills.

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 wasn't ever a huge fan of comics. Just not one of those kids, you know?

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

I was brought up by my mother and my two sisters, although they're older than me and fled the nest very young, so I was technically raised as an only child, but I was very much loved.

I'm not the best audience for that because I'm not a great science-fiction fan. I just never got off on space ships and space costumes, things like that.

Rather like Batman, I embody the themes of the movie which are the values of family, courage and compassion and a sense of right and wrong, good and bad and justice.

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.

People imagine that actors are being offered everything and you are not. So things come in and sometimes there are things that I want and can't get a meeting on, or go to a different actors.

My passion and energy get mistaken for anger.

It's becoming increasingly harder and harder; there's no such thing as independent film anymore. There aren't any, they don't exist. In the old days you could go and get a certain amount of the budget with foreign sales, now everybody wants a marketable angle.

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.

Shakespeare doesn't really write subtext, you play the subtext.

So Harry Potter came in and it is nice that I have kids of the right age. I took them to London and they walked around the set and met Harry Potter and that is thrilling.

'Nil By Mouth' was a bit autobiographical, but as I always pointed out at the time, that's not my dad.

A lazy man works twice as hard. My mother told that to me, and now I say it to my kids. If you're writing an essay, keep it in the lines and in the margins so you don't have to do it over.

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.

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.

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.

At the Oscars, if you didn't vote for '12 Years a Slave,' you were a racist. You have to be very careful about what you say. I do have particular views and opinions that most of this town doesn't share, but it's not like I'm a fascist or a racist. There's nothing like that in my history.

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.

Change is vital to any actor. If you keep playing lead after lead, you're really gonna dry up. Because all those vehicles wean you away from the truths of human behaviour.

Culturally, politically, everywhere you look... Read the newspaper. Go online. Our world has gone to hell.

Getting sober was one of the three pivotal events in my life, along with becoming an actor and having a child. Of the three, finding my sobriety was the hardest thing.

I applaud anything that can take a kid away from a PlayStation or a Gameboy. That is a miracle in itself.

I did have a knack for playing weirdos. There's still sort of this perception of me out there as being this crazy guy.

I didn't do drugs. It wasn't my thing. But the drink was terrible. Today when I look back, it's like I was another person. You could call it a coping mechanism, but that would be an excuse. I just drank too much.

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 don't think Hollywood knows what to do with me. I would imagine that when it comes to romantic comedies, my name would be pretty low down on the list.

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.

I enjoy playing characters where the silence is loud.

I grew up in Deptford in south London, and at that time I used to wear toppers, loon pants and tonic suits from shops like Take 6 and Topman. I was a bit of a soul boy, but I had a very eclectic taste in music - I was into James Brown and Bowie; and I was the only kid in the neighbourhood who would also be listening to Chopin.

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.

I just think political correctness is crap.
