While on a grand world tour, The Muppets find themselves wrapped into an European jewel-heist caper headed by a Kermit the Frog look-alike and his dastardly sidekick.
According to an Entertainment Weekly interview with Kermit the Frog;
“The idea of this film is that our gang is on this global tour, and we’re selling out these grand theaters all over Europe—in Berlin, Madrid, London—but we sort of get into a little bit of trouble when we run across my Doppelgänger. He’s the world’s number one criminal, Constantine, and he happens to look an awful lot like me. I won’t tell you any more than that, but let’s just say mayhem ensues.”
When asked if Kermit would be performing a dual role as himself and Constantine, Kermit responded:
“No. We talked about putting me in makeup and having me play both roles, but we decided Constantine needed to be a guy who could do a Russian accent. And, you know, I’m a pretty accomplished actor and all, but besides The Muppet Christmas Carol and Muppet Treasure Island films, I’ve only really ever played myself. The great thing is, I have like 3,000 relatives back in the swamp, so it was quite easy to find a frog who could play Constantine.”
Nicholas Stoller confirmed that the film would be a caper and that the film’s setting would take place throughout Europe.
