At the D23 Expo in California, the Muppets took the stage, performing a live song and dance number. At the conclusion of the performance, Disney Studios Chairman Dick Cook officially announced that the upcoming Muppet film will be titled The Cheapest Muppet Movie Ever Made (written by Jason Segel).
This title references a project that was to be developed by Jim Henson in 1985 but was never produced. The story features Gonzo directing a Hollywood film and quickly blowing the project’s budget. While it has yet to be confirmed, the new film may mirror the same storyline.
