'Allen Gregory' came about because we wanted an animated show and we were just tossing around some ideas about me playing a 7-year-old. We thought that would be cool, because we couldn't do that in real life.

I always wanted to be a film-maker when I was younger, not an actor. I was an eight-year-old who dreamed of being a writer on 'The Simpsons,' which was a weird dream to have. But I started taking acting classes as a way to learn how to direct actors and I sort of fell in love with it.

I directed my first music video for Sara Bareilles. I like writing and directing. I co-wrote '21 Jump Street' and I'm in that. To me, they all inform the other one. I think writing makes you a better actor, acting makes you a better writer, directing makes you better at both. To me, I'm just trying to learn as much as possible.

I grew up with baseball; I played in Little League and went to games with my dad. But I, as I grew up, became more of a basketball fanatic than a baseball one.

I love my parents. But I'm almost 28 and it's not fun to be asked, 'What are you doing today? What do you want for dinner? When are you going to be home?' It just makes you feel like a kid. It's this juxtaposition of feeling annoyed and really lucky to have people who love you so much.

I play a lot of games on my iPhone. There is a game called Rat on a Scooter that I will promote as much as possible because it has brought me so much joy.

I started writing and acting in these little plays and then I was discovered by Dustin Hoffman. He got me my first audition for a film he was in, called 'I Heart Huckabees.'

I think a lot of actors, sometimes what happens I think is that actors finish a movie and they go, 'Oh my god, I'm never going to work again,' even big huge actors, and so they'll take something thinking that something else will never come along.

I think our culture has gotten so skewed. People assume that because you're an actor you want to write a book to exploit your celebrity, but my celebrity is only a byproduct of me making movies. I have no intention of being a celebrity.

I think this movie, 'Moneyball,' symbolizes becoming a man for me, and I think my character becomes a man. It's important to me: I'm becoming a man. I'm taking my life seriously. I'm taking my acting really seriously, and it's important for me to play adults. It's important for me to change and develop as I get older.

I was thin in high school and then I gained weight. I went to a nutritionist. I learned for the first time about what things are healthy to eat, basically.

I'm really proud of 'Moneyball.' To me, it's about feeling pride in a movie I made. I think when I'm an old man I'll be able to show it to my grandkids with pride. That's all I can really go for: making movies to please me.

I'm sure a bunch of 15-year-old kids would way rather I do 'Superbad 2' than 'Moneyball.' But I would love to do movies like 'Superbad' and movies like 'Moneyball.'

I've never had issues with popularity. I was always a popular guy... I've always had friends and loved ones and everything, so it wasn't like, 'Oh man, I gotta fill some void that was left by high school.' I had a great high-school experience.

It wasn't like, 'I'ma lose weight and start doing dramas.' I wanted to be healthier, and that was the impetus for wanting to lose weight - it's just about being healthy and feeling good.

It's almost like, when someone plays poker for the first time, they might be a professional poker player out of ignorance, just accidentally winning. That was how it felt in my first stand-up appearance.

It's always better to shock people and change people's expectations than to give them exactly what they think you can do. It's not unexpected for me to be in a comedy film anymore; I'm no longer the underdog in that world. Not that I'm great or good at it or anything, it's just that I've done a bunch of them, so you're not shocked.

Look, at the same time that I don't want to be a celebrity, I understand that when you make movies you put yourself out in the public eye. I'd be a baby and a fool to be like, 'Why are there cameras taking pictures of me?' when I'm on a billboard for a movie. I think that's a very absurd concept.

My heroes are Bill Murray and Dustin Hoffman. Those are the two actors that both do comedies and dramas, seamlessly. Also John C. Reilly and Philip Seymour Hoffman. They're all just great actors, neither comedic nor dramatic. They're just great actors.

Once you make a movie like 'Superbad,' when it's popular and you're the lead, you get offered all kinds of things and there's a temptation to make bad movies either for the money or to maintain your relevance in pop culture.
