For years, Frank Oz has been the voice (and hands) of Miss Piggy, but when he got the script for the new 'Muppets' film, he turned it down. "I wasn't happy with the script. I don't think they respected the characters," he tells the British site Metro. "But I don't want to go on about it like a sourpuss and hurt the movie." Oz might remain somewhat diplomatic, but he's not the only one concerned with the 'Muppets' script by star Jason Segel and Nicholas Stoller ('Forgetting Sarah Marshall,' 'Get Him to the Greek'): other longtime Muppeteers are also displeased that the beloved characters' repertoire now includes fart jokes, and the fact that Kermit seems to have become a 1-percenter.
