also, answer to the mystery of Pepe:
"They obviously worked really hard to include everyone. Interestingly, the only post-Jim Henson Muppet to appear in the script is Pepe. He has all of 3 lines so it feels as if they thought "well, we have to have him in there because he's popular but we don't have to give him much time". There are some reverent nods to The Muppet Show and the first 3 movies that really displays the writers' respect for Jim Henson's work. There are a lot of great cameos scripted as well. Of course, we'll see if they can actually get all the celebrities they want to, but it would be nice. It is a musical which, for me, is a plus and hopefully they'll be able to churn out some songs as memorable as we had in the original 3 Muppet movies."
