What's important is the work that you're doing, not the country that you're in. I would much rather be in a play at the Royal Court than in Los Angeles making 'Alvin and the Chipmunks: The Squeakquel.'

Louis Tomlinson, who is a member of One Direction, his mum was a chaperone on 'Fat Friends.' So Louis used to come to the set with his mum, and since I was the only sort of young person around, we would kick a football around, things like that.

BBC3 even started their biggest shows, like Jack Whitehall's 'Bad Education,' they premiered on the iPlayer a week before it went on TV. I think it should always be at the forefront of what is fresh and exciting, and therefore it should be the first channel to exist online.

There's nothing nicer than getting a round of applause for turning up for work. It's amazing! You start work, and people clap. Do you know what I mean? And then they stand up and clap at the end.

You used to have to come to America for 18 months and drive around in a van, trying to get radio stations to play your song. But I remember One Direction's manager telling me that the first time they came to America, they hadn't released a song - they'd only been on 'The X Factor.' But there were 2,000 fans waiting at LAX airport.

Oh my God, I never really tweet, but there's a moment every day I write one and then delete it.

I guess I have a faith. I have an overriding feeling that all of this can't be for nothing. But then I also fully understand that it might be.

Nobody tells you when success comes around; in its transient way, you're just working and exhausted all the time. Sometimes I think I'm just sleeping in the back of cars, d'you know what I mean?

No boys liked Take That, and it was weird if you did because they danced around and wore matching clothes. But I didn't grow up with a dad who told me something was manly or not manly.

No one could have predicted on day one of rehearsals, that a year and a half later we would have shot a film and all be living in New York. It was surreal.

There's a difference between wanting to appear confident and actually feeling confident. I think there have been many times when I've overcompensated for how nervous or out of place I feel. I was like that at school.

When the 'Guardian' is commissioning writers to write obituary pieces about you and your career... it doesn't get much nastier than that. And you've just got to go, 'It doesn't actually matter.'

This arrogance thing... I've had that my whole life. I flip between, 'Oh really? Oh, thank you. Wow. That's amazing' and, 'Yeah! Of course I am.' They're both varying degrees of a self-defence mechanism. It can be from minute to minute that I change.

I was always the kid at school who thought it was a good idea to set off the fire alarm. And much as I'm aware that that's a trait which also propels other things which are good, I wish I could just pause and go, 'Is this really what you want to do?'

I'm very proud of 'Gavin and Stacey,' but I think I have to write something else even to start to consider myself a writer. Just because you do something once, it doesn't mean that's who you are. I played football last night; it doesn't mean I'm a footballer.

It's a tough one for me, politics. I grew up in a house where my father is a Christian book salesman and a Tory, and my mum's a social worker. So I can always see the benefits of both arguments.

I haven't always voted for the same party, mostly because I find that strange. One thing I've never quite understood is when people say 'I'm a Conservative' or 'I'm Labour,' before even hearing what the person running stands for or wants to change.

I knew acting was what I wanted to do. I don't know if I was brilliant at it, but when I was doing school plays, I loved it so much I didn't want it to end. I feel like I'm exactly the same as when I was doing plays at school, to be honest.

I think everyone at school experiences some form of bullying. With kids at school, it can be anything - it can be your shoes or the wrong bag or anything. If you are big like I am, you are always going to be a target. So I decided at school to make myself an even bigger target, if you like: to make myself as big as I could be.

On stage, you have to have incredible confidence, or you would stop doing it. But I don't think I will ever get to the point where I go, 'I know exactly what I am doing,' and I don't think I want to.

The truth of why I used to listen to Arrested Development on my Walkman was because if I didn't, it would take me 20 minutes to walk to school. If I did, it took me 15. That's the reason I loved it. I just had more of a kick in my step, more of a bounce, so I'd walk quicker.

I went through a stage of wearing quite lairy trainers. I had all these trainers in gold or pink or silver. I look at them now in the cupboard - what was I thinking? Such an awful idea.

It's a strange thing, this idea that for some reason, if a lot of people like what you're doing, it's therefore not very good. We use the phrase that a band have 'sold out.' Just so you know, if you're doing a gig and you sell all your tickets, that is a brilliant thing to do.

I want to act, I want to write, and I need to follow good directors.

You can either hope and pray you don't get picked on, or you can, in a way, almost make yourself a bigger target, because it's harder to bully something that's really big. It's easy to bully something that's small and frail.

You can't make anything without making mistakes, do you know what I mean? Robert De Niro's in the 'Rocky and Bullwinkle' film. There's a lot of far greater people than me who have made mistakes in their careers... There's loads of people who have made stuff that isn't good and never get asked about it.

I'm not sure people even think of me as an actor at all.

'Lesbian Vampire Killers' was quite embarrassing.

I've never seen the film 'Gulliver's Travels' - and I'm in it.

People say: 'Oh, but would you be happy for your show to go on BBC3 if it was just online?' If I was sat here telling you I had just signed a huge deal with Netflix you'd be going: 'Wow, that's amazing.' You can't see it as 'Oh, it's no longer a channel because it's not on TV.'

There is really no one who hasn't made mistakes in their career. I'm always shocked that people would be so surprised that I might make mistakes. Martin Scorsese has made mistakes - why can't I?

I saw Boy George looking amazing, absolutely unbelievable, and messaged him asking for the number of his nutritionist. I got in touch with her, and she put me on this diet plan, working out which foods do and don't suit me. It's not rocket science - basically, don't eat cake, don't eat bread.

I want to be Gary Barlow and peak when I'm 40. That's my plan - he's who I'm modeling myself on. Most people are completely beautiful when they're young, and then there's always a point when they get older where they say: 'Oh, what happened?!'

My biggest tip is this... treat bread like chocolate. You wouldn't have a chocolate bar in the morning and then a double chocolate bar at lunch and then some chocolate before dinner. I was essentially eating a loaf of bread a day. And that doesn't work for me.

It's enough now of being unhealthy. I have a family, and I owe it to them to be as healthy as I can. A great sense of clarity comes when you have a child. It shows the important stuff to be important.

It is hard because I love Cornettos, so that will always be a weakness, and I've realised that bread is my nemesis. I believe bread has been sent to destroy me to the core.

My major ambition is just to stay relevant.

I've been lucky enough that in the U.K., I've done shows that have aired once a week. I make a show there that runs seasonally, and we make one episode a week, and that is great - the value of time. You can really think and finesse what you want to do.

I enjoy, always, the feeling of being in front of an audience.

The positivity of the Obamas as a family is undeniable.

If you're big at school, you've really got two choices. You're going to be a target. If you go to school, and you're me, you go, 'Right - I'm just going to make myself a bigger target. My confidence, it will terrify them.' That's how I felt in school.

I could never understand, when I watch romantic comedies, the notion that for some reason, unattractive or heavy people don't fall in love. If they do, it's in some odd, kooky, roundabout way - and it's not. It's exactly the same.

I met my wife; she barely owned a television and worked for Save the Children. We sat down one night, and we fell in love, and that was it.

I have friends at home who love 'The Tonight Show' with Jimmy Fallon. They live in the U.K., and they've never seen an episode, but they love it.

I'm very lucky, in that I've known Adele for quite some time.

I'm not a stand-up comedian; I'm not a satirist.

First concert I saw was a British boy band called Take That when I was 14 or 15. I went with nine girls from school.

I think the weather here is a big attraction for anyone. But also, there are more creative people per square mile in L.A. than anywhere in the world. They make 'The Simpsons' here. Anywhere they make 'The Simpsons' is a good place to be.

I don't want to feel like I'm a television host - because I don't think that I am. What I really want to feel like is, I am you; I just happen to be here.

I'm never going to try 'Carpool Karaoke' in New York. That would be a very different thing. Mariah Carey's one, we just drove, like, five or six blocks round where she was staying at the time.
