'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 assume everything I do in life is gonna be a failure, and then if it turns up roses, then I'm psyched.

All my friends were in college when I was making 'Superbad.' We were drinking beer and watching movies and eating pizza. It wasn't like I was going to nice restaurants or anything like that, and I lived like a frat guy. Eventually it was time to grow up, be healthy and be responsible. You can't live like a kid forever, you know?

'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.
