My idol growing up was Charlie Chaplin. I was obsessed with him. I mean, while other kids were watching Jim Carrey and the likes in the '90s, I was watching Charlie Chaplin films, because I was a bit of a geek. I became obsessed with this idea of physical comedy.

I certainly never imagined 80-year-olds singing along, like they were watching Cats. I'm fascinated by that kind of pop cultural zeitgeist that it's attached itself to.

I was a product of a divorced family and I used humor as a weapon to combat sadness. I used comedy to make my mother laugh in light of the darkness that she faced, and to me it became a very powerful tool at a very young age, at six. I saw how therapeutic it could be.

In real life, Josh [Gad] is a different kind of lovable idiot. In real life, he's a much filthier idiot. He has a dirty sense of humor.

Josh [Gad] is such an amazing improviser and is so good when the material is flowing from him that sometimes, if a written scene isn't working quite right, I'll tell him that we've got it and that he can just play. He'll blow us away with some super weird stuff and some wild things that we might use bits and pieces of in the edit, and then I'll say, "Just for good measure, let's do one more of the scripted version."

Melissa McCarthy just opened this new movie, “Identity Thief,” and Rex Reed, who’s a known critic, wrote a scathing commentary on her weight. I think that weight designation is one of the last frontiers of bullying. I don’t know what the right “ism” for it is, but I think that there’s a level of that that’s happening that’s certainly not okay.

I think “The Book of Mormon” has made that difference in its field. It changed the game. It’s something that 20 years from now people will still be talking about, hopefully. That’s my goal as an artist, as a creator, as a work for hire, is to choose projects that make people think, make people talk, and make people interested in having a dialogue.
