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.

The team we had, the Hobie Vita-Pakt Super Surfer team, you know, the Hilton boys were on there, Conrad Hilton's grandkids, and they were really good. After being around those kids, I could ride a little. Do a 360, some kick-turns, stuff like that.
