But it's one thing to have other actors you can bounce off of, what's it like just riffing alone in a room?


There's something very liberating about it. Although I've never been diagnosed, I'm pretty sure I've got ADD. So for me just going into a room and talking to myself over and over again and just scream into a microphone it's a perfect form for my insanity. I love it. I love working with actors. But there's something about the challenge of only having your voice as an asset. About telling a full slate of emotions, a full story, creating a fully bodied character with nothing but the tone, the cadence of your voice. So to me, there's something really exciting about that. There's also something doubly exciting because it's also an opportunity for me to sing, which is something I've never had a chance to do on film before. I did in Book of Mormon I've worked with Bobby Lopez before, but to go and create this character that also has this amazing song in the film, I was pinching myself.

Let's talk about the relationship between you and the past Book of Mormon songwriters [Robert Lopez and Kristen Anderson-Lopez] who created the songs for Frozen. What's the difference between singing on stage for these people you know versus singing for Disney? Is it easier having someone you've worked with before or harder?


Well, there are a lot less F bombs in this particular production. I was actually involved with Frozen before Bobby was. I did the very first reading before Book of Mormon even existed. The movie was called, at that time, Anna and the Snow Queen. It was completely different. And I thought the project was dead. Then I find out that Bobby's doing it three years later, and they come back to me and I'm doing it again. When Bobby called me about the song that we're going to do… Bobby understands my voice probably better than anyone else, so he knows some of the goofy elements. And I don't know that anyone else would have written it to have this sort of operatic ending that it's got, which is so bizarre and funny. But he knew the quality of my voice and the goofy things that I do. So he was I able to pull from that.

So singing for a Disney movie, again you play these images back in your head. I remember seeing a behind-the-scenes video of Robin Williams singing "You Never Had A Friend Like Me" and so to then to be in that room, to do that. To have a full orchestra creating that Disney sound. And knowing that kids are going to forever have that, cause God knows that kids can't sing "Man Up." I can't tell you how exciting that is.

How much did Frozen change? How different was your character and the other characters?


From when I first started? Completely different. In the very first reading I did, we had Megan Mullally played Elsa. That alone should give you an idea. She was brilliant, but it was a completely different story. The whole thing took on a life of its own once this creative team came on board. Even during the process of the second incarnation, the version people are seeing now, it kept changing. And it kept getting better, and better, and better as the project went forward. They're not afraid to understand when something's not working and to say "ok we gotta go back and change this." They would bring me back in and I would say, "oh what happened to this scene?" And they would say, "well you know what, it just wasn't tracking with the rest of the story so we're going to start from scratch." "Don't you guys have like five weeks left to animate?" But that's what they do. It's incredible.
