Ladies and gentlemuppets, the first extensive details on Muppets sequel The Muppets...Again! have been announced and it's all sounding pretty good to us. We already knew that Tina Fey, Ty Burrell and Ricky Gervais were among the cast - but now we know a little more about what they'll be doing.

According to the official synopsis, this film, "takes the entire Muppets gang on a global tour, selling out grand theatres in some of Europe’s most exciting destinations, including Berlin, Madrid and London. But mayhem follows the Muppets overseas, as they find themselves unwittingly entangled in an international crime caper headed by Constantine—the World’s Number One Criminal and a dead ringer for Kermit—and his dastardly sidekick Dominic, aka Number Two, portrayed by Ricky Gervais."

As we already knew, Tina Fey plays Nadya, a feisty prison guard, and Modern Family's Ty Burrell is Interpol agent Jean Pierre Napoleon (so he's Italian? Wait - German?). That's along with the regulars like Kermit the Frog, Miss Piggy, Gonzo, Fozzie and the rest.

The good news continues with the word that Bret McKenzie will once again be composing songs for the film, and the fact that it will be shooting in London - Pinewood, in particular - as well as in Hollywood.

Bobin said, "It’s great to be back working with the Muppets. Some of them even remember my name occasionally now. As for the movie, it’s a tip of the hat to the old-school crime capers of the ’60s, but featuring a frog, a pig, a bear and a dog—no panthers, even pink ones—along with the usual Muppet-y mix of mayhem, music and laughs."

Kermit added, "This movie takes us places we’ve never been before. And trust me—this frog has never seen so much international flavour. I think audiences will eat it up—the entertainment, that is."

The Muppets... Again! hits cinemas on March 21, 2014.
