When someone who is known as a comedic actor goes to drama, it often doesn't work out, because they really just chose wrong, I think - or maybe they're just not good actors. For me it's important making that transition seamless, and not a huge shock and jumping into cold water. It doesn't feel like I'm trying to shock you or anything. I'm just saying, "I'm a different actor than you thought I was. Don't put me in a box. I'm not just some kid running around screaming curse words." I have other tastes besides comedy. I love comedy, but I love dramatic movies just as much.

I want to meet the man who saw a turtle and said, "People will LOVE the ninja version of that."

I'm very, very attracted to morally ambiguous characters, not just pure bad guys or pure good guys.

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.

'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.

One of the greatest moments of my career was on the road promoting 'Superbad' with Michael Cera and Chris Mintz-Plasse. We were showing the movie at colleges.

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.
