The show is probably 60 percent improvising and 40 percent not. So there's quite a bit of it that we do have prepared and that part of it, you have memorized and you've rehearsed and you're prepared, just like any show.

People would say to him, "When you finish a movie, did it come out as good as you thought it was going to?" Or, "Did it come out the way you intended it to come out?"

I think initially it's terrifying because going into a show where, you know, "Oh, I'm going to be on stage for two hours, I have no lines to memorize, I have nothing really prepared," and actually I say that, the show is not all improvising.

The first big thing that I did with my dad was the bicycle sequence in "The Great Muppet Caper," where Kermit and Piggy are riding bicycles in Battersea Park in London and that was a complex marionetting and cranes driving through the park, it was a complicated scene, and I did that with my dad.

I try to emulate his approach of really get the most out of people by allowing them to experiment and certainly allowing people to make mistakes.

So while you're trying to improvise, you're also trying to puppeteer, you're doing everything that you need to do to perform a puppet in our style, for a camera.

And it was a whole lot of fun, and in many ways, what we've done with the show is just taken that part of my early memories of visiting my dad, shooting with the Muppets, and taking that and making a show that's really an expansion of that and presenting a show that's all that.
