Funny enough, there have been puppets in everything I've written because I have a huge love of puppets. There's a big puppet musical at the end of 'Sarah Marshall.' I wrote 'The Muppets.'

I was a huge Muppet fan growing up. I want to bring it back to the early '80s Muppet movies, when the scripts could have been performed by humans.

One thing that I think never goes out of style is just purity. Niceness and purity. And the Muppets have never lost that. Kermit especially is just wide-eyed wonder, unblinking. And he can't blink. Which I think probably helps.

You know, a carving, especially if it’s polychrome, is not meant to move. These faces, these half-bodies, when you animate them, they’re more live than the living. They can be dangerous for those who don’t really understand them. With contained energy, no one can predict what will happen when it’s released.

Fozzie Bear has so many bear puns in this script - like, 'Trac is grizzly!' 'This is unbearable!' It's the greatest.

I sold my first script when I was 21 - this kids' adventure movie that never got made. I just bought that one back, actually. I'm pretty psyched about it.
