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.

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.

It's funny because The Book of Mormon is The Book of Mormon now. When I was doing it at the very beginning, and I was a part of it for four years and always believed in it, I never really knew if it was going to be more than a convention for South Park fans.

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.

Part of our goal, in the episodes moving forward, is to deepen and dimensionalize every other character, to get into their relationships with each other, expand that stuff and really sink our teeth in.

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."

I grew up on 'Lawrence' and 'Zhivago'. A legacy with not one but multiple timeless classics.
