I played bass for a year, but I wasn't getting better at it, so I decided to stop so I could see my friends.
I pretty much left full-time, formal education when I was 11, so that was when I was taken out of the school system... The longest stretch I would go back for was a term and a half when I was about 14.
The American version of 'The Office' is fantastic.
My mom and dad were actors when they were younger and had a horrible experience of it. My dad became a literary agent and my mom a casting director.
I think, as an actor, and particularly if you are playing the lead in something, you have to view yourself as the head of department for the cast. All of the other departments are accountable and have somebody at the helm who is leading them all the time, and I don't think that the actors should be any different.
I was in the bath at the time, and my dad came running in and said, 'Guess who they want to play Harry Potter!?' and I started to cry. It was probably the best moment of my life.
I've been working since I was 9, and I've never known a life without a film set.
I just moved into the world of Xbox Live. And I've discovered that everyone on the Internet is a lot better than me. I spent half an hour the other day designing a boxer, and I got knocked out twice in the first round.
My parents are left-wing, and I would describe myself as that. But also, you know what? I wouldn't describe myself as that. Because I don't have to. Because I'm not a political party. Most people are a little bit of each, and we change our mind on various issues.
I'm 5-foot-5, and I'll wear a big parka and put the hood up, and nobody gives me a second glance.
It's very rare that I get stopped or get asked for an autograph or anything - none of which I mind - but people don't really care that much.
Directing is more what I would like to get into eventually. Frankly, I feel like it would be a waste if I didn't because I've spent so much time on film sets, and I know how they work, and I love them, and I love leading them. I would like to do that as a director definitely.
I love Steve Carell and Will Ferrell - they're my heroes.
I am a frighteningly thorough person.
England is my home. London is my home. New York feels like, if I have to spend a year living in an unfamiliar city, this is a pretty lovely one to spend a year in, but I will be going home at the end of it, certainly.
There's an incredible comfort level that I have on film sets because it's where I've grown up.
I suppose whenever you go through periods of transition, or in a way, it's a very definite closing of a certain chapter of your life - I suppose those times are always going to be both very upsetting and also very exciting by the very nature because things are changing and you don't know what's going to happen.
There's no blueprint for where I should be. I see myself as a young, good actor who still has a lot to learn. There's nobody at any point in their career who is the finished article.
It's interesting because people assume that because I'm famous I know all famous people.
A friend often says I'm an old man in a young man's husk. I like that. I am old-fashioned in some ways.
I think it would be very hard to go out with an actress, because they're mad. Some actresses are just insane. I've never worked with a nasty actress - they're all absolutely delightful. But completely barking.
What I learned is that acting is to a large extent about trying to stave off self-doubt long enough to be natural and real onstage.
I'm never going to be in something as commercially successful as 'Harry Potter' ever again. It's impossible. So that gives me incredible freedom to go off and make the slightly off-the-wall films that I want to make.
I absolutely don't relate to being beaten down my whole life - I had amazing opportunities at a young age - but there is still in many, many people's minds the notion that I'll never be able to escape Harry Potter.
I get constantly mistaken for Elijah Wood.
Being self-critical is good; being self-hating is destructive. There's a very fine line there somewhere, and I walk it carefully.
There is something inherently valuable about being a misfit. It's not to say that every person who has artistic talent was a social outcast, but there is definitely a value for identifying yourself differently and being proud that you are different.
I'm very interested in religion as something to study, but I'm not a religious person in the slightest.
The most wonderful thing I hear is people coming up and saying 'Thank you for my childhood', which still blows my mind but is very sweet.
People do incredible things for love, particularly for unrequited love.
There are lots of times when I'm a very good boyfriend, but there are times when I'm useless. I mean, I'm a mess around the house. I talk nonstop. I become obsessed with things.
And the people I'm best friends with on the films are not generally the actors.
Dane DeHaan, certainly, is kind of the best friend I've made through acting, in terms of another actor. He's fantastic.
