'The Muppets ... Again' stills spotlight Ricky Gervais, Kermit the Frog and Miss Piggy

Disney's all new Muppet movie, "The Muppets ... Again," is moving full steam ahead and the company has released the promotional images to prove it.

The first still spotlights new celebrity cast member Ricky Gervais, who plays the henchman of Kermit's evil doppelganger Constantine -- the world's No. 1 criminal.

The second still spotlights the entire Muppet cast, who will be front and center in the international caper sequel. The action takes the Muppets to Berlin, Madrid and London and also features Tina Fey as a "feisty prison guard" and Ty Burrell as an Interpol Agent.

Unlike 2011's "The Muppets," which prominently featured Jason Segel and Amy Adams, the humans sound like they'll be less important this time around. However, the behind the scenes team is largely the same including director James Bobin, co-writer Nicholas Stoller and music supervisor Bret McKenzie.

"The Muppets ... Again" is scheduled for release March 21, 2014.
