EW has new details that clarifies a lot of the information that's been coming out, including the news that the movie will be titled The Muppets... Again!
|The sequel finds our heroes enjoying a triumphant world tour, only to become tangled up with a criminal mastermind named Constantine, who is out to steal an enormous diamond—and who happens to be a dead ringer for Kermit"|
EW goes on to say that Gervais actually plays the villainous sidekick of Constantine, Fey will be playing a Russian prison guard, and Burrell will play a French Interpol agent.
Gervais definitely seems like a better fit as a comedic flukey, rather than a protaganist friend. I'm interested in seeing who they get for cameos and/or minor roles.
As for the Muppets, I wish they would give Rizzo a more prominent role in this one. I always liked the comedy bits in pairing him with Gonzo.
