Muppets that get their own scenes are Fozzy, Gonzo, Miss Piggy, Animal, Bunsen & Beaker, Rowlf, and the rest is montaged.
So I guess that means the rest of the band wasn't with Animal when the Muppets get back together. Sigh.
The Electric Mayhem was perfect. Unfortunately I don't remember Janice having any lines.
You could just be misremembering, but if Janice doesn't have any lines, then I think it's odd they chose to make a Moopet resembling Janice (I already thought it was odd Janice had a Moopet counterpart without the rest of the band included).
Do all of the Moopets have names? I saw a Moopets t-shirt which was a gift to the cast and crew, and it depicted a human among the group. Do you know who this human was supposed to represent (Jim Henson? Sweetums? A guest star?)?
I wrote an article for The Muppet Mindset recently listing characters I want to see in the film who haven't been spotted in the trailers (Ryan Dosier added a few to my list). My list is here:
http://themuppetmindset.blogspot.com/2011/07/muppets-not-in-muppets-trailers.html Do you remember if any of the characters in that list appear in the film?
I assume that Steve Whitmire performed Link, Matt Vogel performed Dr. Strangepork, and David Rudman performed Wayne, but do you happen to know who performed Wanda in this movie?
Finally, were there any scenes with so many characters that it was hard to spot everyone in just one viewing?
I must say, with you joining the forum right after seeing the movie before the rest of us, I figure this thread'll help you reach 100 posts soon (not sure if that's a goal of yours).
