Amy Adams, Chris Cooper and Rashida Jones are to join Jason Segel in the previously titled 'The Greatest Muppet Movie Ever Made', which now seems to have been strangely re-titled "The Muppets.'
Adams is in line to play Segel's girlfriend, who helps reunite the Muppets for a fundraising show to save a movie studio in danger of being torn down.
Cooper is to play the evil tycoon who hopes to dig for oil below the studio, while Jones is expected to play an ABC television executive.
The James Bobin directed film is scheduled for a Christmas 2011 release.
