The Muppets are back in a blissfully funny, cross-continental caper. Seems that the World's Most Dangerous Frog has escaped from jail and switched places with our beloved "Muppet Show" host, Kermit the Frog. While Kermit tries his best to escape from a nutty Russian gulag, his evil doppleganger uses the Muppet's European tour as cover for a series of daring art heists. There are dozens of cameos and tons of nostalgic humor perfect for young and old. 112 minutes PG.
