There was a 10- and 8-year difference between us, so my brothers were into tormenting me and I was into getting away from them.

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

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."

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.

When you get into the series, the progression is much different. You actually have breathing room and the chance to sit down with each actor, which was a part of our process, to talk to them about their pasts.

Hollywood is the kind of place that takes what you do well in one thing and manufactures it so the joy can be taken out of it.
