You just have to be strong and don't be stupid; freedom of choice is a big responsibility.

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.'

As a writer, I haven't delved into dramatic writing. As an actor, I could always, even more so than comedy, do drama.

You have more of a responsibility to make the audience laugh. In comedy, we do have to say, "All right, it's been two minutes in the film. We need another laugh here." With drama, there's no pressure in that regard. It's a different kind of pressure, but it's not like we need to make someone laugh.

I couldn't imagine someone playing me or writing a book about who I am. Although I let people write articles and try and express who I am, and it blows up wildly in my face.

'Funny People' is my favorite performance of myself to date. Even though it's a comedy and there are serious moments, I really felt like Leo felt like a real person. It didn't feel like I was playing myself. Whether it's a comedy or drama, I just try to make it as realistic as possible.

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.
