Jonah Hill

'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.

'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 think about fanaticism - oblivion awaits, especially for minor writers, so you have to be a fanatic; you have to be a crank to keep going, but on the other hand, what else would you do with the rest of your life? You gotta do something.
