NBC has lined up an all-star cast for A Very Merry Muppet Christmas Movie, the first-ever made-for-television Muppet film. Whoopi Goldberg, Joan Cusack and David Arquette will join Kermit the Frog, Miss Piggy and the rest of the gang in the pic, which airs in December and finds America's favorite frog fighting to save the Muppet Theater from a Scroogish bank owner. Look for cameos by Sir Michael Caine, William H. Macy, Snoop Dogg, Carson Daly, Kelly Ripa, Jon Stewart and Rachel Hunter.
