I feel like Jim Carrey is probably the closest thing to a true physical comedian that we have working today.

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.

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.

Josh [Gad] does such an amazing job playing a lovable idiot. Not many people can do that, as convincingly as he can.

When you're doing a show like 'The Book of Mormon,' you're completely spent by the time the show is over.

We use improv in all kinds of fun ways. Sometimes it's to invent or discover new things, sometimes it's to weird out the other actors, and sometimes it's to create a sense of fun, to find new things inside the scripted lines.

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.
