1. I'm in "I'll believe it when I see it" mode (absolutely no offense meant to theprawncracker) but I'm enthused to hear even preliminary reports that Bobin and Stoller are back on board - and, as mentioned earlier, these reports are popping up before The Muppets even arrives on DVD and Blu-Ray, which should give this already-successful "comeback movie" another huge boost.
Like I said, most movies that get sequels now get the announcement after the first week at the Box Office. If it's a success, a sequel is no doubt. Half... ehhh... most of the time, these are, like I said, Hangover 2... basically a rehash of the same movie because they were too short sighted to realize that said sequel has to have a PLOT that differs enough from the first to make the film worth seeing. Hopefully, they know that in this case. Jason's not on board, but he did say that it was "more Muppety" if they just do a different follow up movie.
2. The movie can work with or without Segel, on-screen (the return of Walter doesn't necessitate the return of Gary or Mary) or off (I'd be heartbroken if he wasn't on board at all but I trust Bobin and Stoller to get this right, although I wouldn't mind seeing Lewis or Oz in the mix - and might a certain Oscar-winning Mr. McKenzie come back to write some more great songs???).
5. I'll echo DrTooth's comment that there may just have been too many Muppets crammed into the most recent film. Don't get me wrong, I loved the great "all hands on deck" TMS vibe in the second half of the movie and it's sometimes fun to play "Who Do You Recognize?" but not if it distracts from the flow of the film or denies other characters their chance to shine. Count me in on the "More Screen Time for Gonzo, Rizzo and Pepe" camp (and I'd throw Rowlf, Robin and the Electric Mayhem in there for good measure - maybe even Johnny and Sal too).
Well to be fair, as much as some fans like that era, it was not the Muppets most successful time. The post-era era had 20 years to win the public over and overall it didn't. In fact it turned off a lot of people.
Here's the thing about Muppets Tonight and all the other post-Henson projects... Jim died, Richard died, Frank Oz had a foot out the door. Only Kermit was fully recast then, and even then it seemed Steve rather performed Rizzo than Kermit for some time. If you don't believe me, check out the commentary of Muppets From Space. Kermit gets "lost in Star Wars episode 1" for most of the movie, and Rizzo takes his place. Of course, Kermit was a very personal character to Jim, while Rizzo was one Steve created. But Steve has proven that he can be Kermit, and we've seen a LOT more of him since VMX than any time from MCC-MFS.
So what can you do if you don't have Rowlf, Dr. Teeth, Scooter, Janice, as well as a host of others that have yet to be recast? You have to make new roles to fill in those spaces. That was where Pepe, Johnny and Sal, Van Neuter, Bobo and a whole mess of less fortune ones came in. Now, the cream of those characters survived MT (no Poodlepants, Spamella, or Andy and Randy... except for that one Cat Cora thing)... but now you figure, Clifford was Kevin Clash, who's way too busy with Elmo and his other massive list of SW duties... so he's out. Brian is with Henson, so Sal and VanNeuter aren't there either. So basically we have a Sal-less Johnny (much like the toy line), Pepe, and Bobo... all Bill's characters.... and now Bill gets the recast for Rowlf and Dr. Teeth as well. So, the irony is, we're actually losing the new characters unless they get recast as well.
On that subject, we have recasts of older characters we once lost. Look at the TED conference... David brought Scooter
back. We're seeing more of characters like Link Hogthrob (who basically got more screen time in The Muppets than any of the previous 6 movies combined), Rowlf, the entire Electric Mayhem... not to mention the massive Eric recasting of all of Frank Oz's roles. We finally have all the characters, or at least most of them, back where they belong. Without those new characters created in MT or recasts, we'd basically have just Gonzo and Rizzo.
Still, Pepe has proven to be one of the group since MFS... arguably the only really great thing about the post Henson era. And even then, they managed to squeeze him in, while splashing him all over the promotional materials. Rizzo was barely a cameo at the end, though, like I said, I don't see where he'd fit in, and we've got a LOT of Kermit in this movie, so Steve was clearly busy.
