UPDATE: No, he's not.
Christoph Waltz is in negotiations to join the cast of Disney's sequel to The Muppets in a starring role.
Waltz, the Academy Award-winning Inglourious Basterds star who will next appear in Quentin Tarantino's holiday release Django Unchained, would play an Interpol inspector in the Europe-set comedy.
The Muppets, released in 2011 as a relaunch of the long-running Jim Henson-created franchise, was co-written by Jason Segal -- who also starred in the film -- and grossed $158 million worldwide. Segal is not returning for the sequel.
While the film is expected to have a slew of cameos, as is a Muppets movie tradition, the part of the Interpol inspector is one of a small handful of human roles that will stand apart. The other notable characters, according to sources, are that of a Russian femme fatale and a male lead whose intentions are always in question.
James Bobin, who directed the 2011 Muppets film, is returning to helm the follow-up; he co-wrote the screenplay with Nicholas Stoller.
David Hoberman and Todd Lieberman, who produced The Muppets, are back to produce the sequel.
