The Muppets Start Filming "Again"!

Production has started on "The Muppets 2" officially titled "Muppets...Again" says a press release.

In this Europe set adventure there are a trio of key human roles--Tina Fey will be playing a Russian gulag prison guard Modern Family star Ty Burrell will play the key role of an Interpol official--Christoph Waltz was originally in talks for that part--Ricky Gervais is playing a character with questionable intentions. There's also likely going to be a number of celebrity cameos--including Ray Liotta

Here's the official synopsis:

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. The film stars Tina Fey as Nadya, a feisty prison guard, and Ty Burrell as Interpol agent Jean Pierre Napoleon.

The Muppets human star/co-writer Jason Segel, will not be returning for the follow-up, but director James Bobin is coming back. Bobin co-wrote the script with Nicholas Stoller.

Bobbin proclaims:.

"It’s great to be back working with the Muppets, some of them even remember my name occasionally now," the director said. 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."

The film is due out on March 21, 2014.
