Changes

The plot for the 3D Muppet film came about during brainstorming meetings between WDI and the Henson team<ref name= "Korkis"/> . Henson writer Bill Prady was tasked with writing the plot, which initially focused on newly created Muppet Bean Bunny<ref name= "Korkis"/>. Although Henson wanted to promote his new character, Imagineers informed Henson that the theme park audience would respond better to well known characters<ref name= "Korkis"/>. According to show producer Mark Eades: {{Quotation|"Jim was very involved with the project. He was genuinely interested in doing theme park attractions. I think Jim liked that it would be something people could see for a long time in an environment like a Disney theme park. I think he also liked doing something new, unique and groundbreaking."<ref name= "Korkis"/>}} Filming of the new Muppet film began in California, with the Miss Piggy sequence being the first scene to be shot <ref name= "Korkis"> http://allears.net/ae/issue756.htm </ref>. Although construction on the 3D theater for Muppet Movieland was underway, Jim Henson's tragic death in May 1990 caused the merger between the companies to fall through <ref name= "Seattle"/> http://community.seattletimes.nwsource.com/archive/?date=19910519&slug=1284051 </ref>. Without Henson, Disney's interest in the Muppet's waned, and Henson's estate balked at Disney's offer to purchase the Muppets. The falling through of the merger led to a biter lawsuit being filled<ref name= "Seattle"/> .  Shortly after Henson's death, frequent collaborator Frank Oz took over directing duties on Muppets 3D <ref name= "Korkis"/>. With negotiations between Disney and the Henson estate breaking down however, the Henson family asked everyone working on the film on their side to stop. According to Mark Eades, Disney Imgagineering then had to complete the film alone:{{Quotation| we had to finish the film, including all the Waldo CGI, much of which was added as a result of the new stuff, without them, including all the performers. We had already done the looping so we had all the dialog."}} On May 19, 1991 however a confidential settlement was reached between the two parties<ref name= "Seattle"/> . As part of the agreement, Disney was allowed to continue their development of the 3D Muppet attraction, and they were given merchandising rights for 18 months<ref name= "Seattle"/> . Henson's son Brian, felt that releasing the Muppet 3D film would be a fitting tribute to his father <ref name= "Korkis"/> . Although in the end the Muppets would come to Disney-MGM Studios, the plans for integration were drastically cut back. Instead of Muppet Movieland, Disney instead constructed the 3D theater and a Muppet area surrounding it<ref name= "Martin"/>. Finally, on May 16, 1991 Jim Henson's Muppet Vision 3D opened to guests <ref> http://thisdayindisneyhistory.homestead.com/May16.html </ref>.

Although no changes have to the Muppet Vision 3D show itself, the attraction has seen some minor changes. In 2005, Jim Henson's name was dropped from the attraction, with the attraction being renamed simply “Muppet Vision 3D”. In 2006, the attraction's entrance sign was changed. Jim Henson's name was removed from the sign, and drawings of Miss Piggy, Fozzie, Gonzo, Dr. Honeydew and Beaker were added. In 2009, new parody posters were added to the show's queue including spoofs of: Hamah Montana, Pirates of the Amphibian, High School Mayhem, Wild Frogs and BEAK•E. Finally, in 2010 the projection system used in the show was updated.Leading up to and following the release of the 2014 film Muppets Most Wanted, Constantine (the villain of the new film) was added to Muppet Vision 3Ds preshow <ref> http://www.wdwmagic.com/attractions/jim-hensons-muppetvision-3d/news/21mar2014-muppet-vision-3d-to-receive-new-pre-show-this-week-to-promote-'muppets-most-wanted'-movie.htm </ref>
