If your kids are big fans of the Muppets, you're in luck. Disney's “The Muppets .?.?. Again!” sequel is expected to hit the big screen March 2014.

Currently filming in London and Hollywood, the Muppets head on a world tour to film in some of Europe's most desirable destinations, including Berlin, Madrid and London. Joining Kermit the Frog, Miss Piggy, Fozzie Bear, Animal and the rest of the Muppet gang are Ricky Gervais (creator of “The Office"), Tina Fey ("30 Rock” and “Mean Girls”) and Ty Burrell ("Modern Family").

The movie follows the Muppets on an overseas tour as they find themselves entangled in an international crime caper headed by Constantine -- "the World's No. 1 criminal and a dead ringer for Kermit.” His sidekick, Dominic, aka No. 2, is played by Ricky Gervais. Tina Fey stars as Nadya, a Russian prison guard, and Ty Burrell as Jean Pierre Napoleon, a French Interpol agent. And, be on the lookout for other celebrity cameos.

Kermit the Frog said this in a recent interview with Entertainment Weekly about his human co-stars:

“Ricky Gervais is kind of like a Muppet, if you think about it. He fits right in. He’s about our size. I actually think when this film ends it’s going to be hard to get rid of him. He keeps following me back to my hotel in London, which is very strange, but we’re thrilled to have him. Then, of course, we have Tina Fey -- and it’s hard to beat Tina. She’s playing a feisty prison guard named Nadya, which should be fun. Then we have Ty Burrell, who’s playing a French Interpol agent. But personally, I’m not going to be going to France for the French scenes. It’s best if I don’t go there. It’s a frog thing.”

Disney's “The Muppets .?.?. Again!” is directed by James Bobin and produced by David Hoberman and Todd Lieberman. For more information, visit Disney.com/Muppets.
