Muppet*Vision 3D is a 3D film attraction located at Disney's Hollywood Studios. The attraction also formerly operated at Disney California Adventure. Directed by Jim Henson, the attraction consists of a pre-show which then leads into Kermit the Frog guiding park guests on a tour through Muppet Studios, while the Muppets prepare their sketch acts to demonstrate their new breakthrough in 3D film technology. The show, however, completely unravels when Dr. Bunsen Honeydew's experimental 3D sprite, Waldo, causes mayhem during the next portion of the show. The attraction—which opened as Jim Henson's Muppet*Vision 3D on May 16, 1991 at Disney's Hollywood Studios (then Disney-MGM Studios)—incorporates the 3D film in conjunction with in-theater 4D effects, such as Audio-Animatronics, lighting, projections, smoke, soap bubbles, and a live full-bodied performer. Muppet*Vision 3D had a subsequent incarnation which opened in Disney California Adventure on February 8, 2001 and operated at the park until November 1, 2014. Muppet*Vision 3D is the sole attraction of Grand Avenue in Disney's Hollywood Studios. History The show is a 3D film featuring Jim Henson's Muppets. Due to the use of Audio-Animatronics, a live full-bodied Muppet and other similar effects, the show is sometimes referred to as "Muppet*Vision 4D" (which was used in The Walt Disney World Explorer application, displayed as "Jim Henson's Muppet*Vision 3D 4D" with a slanted red strikethrough on "3D"). It was filmed in Soundstage 3 at the Walt Disney Studios in January 1990 and directed by Jim Henson and written by Bill Prady. The show was one of the final Muppets projects with the involvement of Henson, as well as veteran Muppet performer Richard Hunt, and was the last time they performed their characters. Henson died in 1990, before production of the film was completed, and Hunt died in 1992. On August 28, 1989, Disney announced that they had an "agreement in principle" to acquire Henson Associates and the Muppet characters, and that a 3D Muppets attraction would debut at Disney-MGM Studios (now Disney's Hollywood Studios) the following May. Jim Henson died before the attraction could debut, and as a result the acquisition was cancelled and the attraction, now known as Muppet*Vision 3D, was delayed. An agreement to license the Muppets characters for the theme park attraction was reached, and it officially opened on May 16, 1991, the first anniversary of Jim Henson's death. On February 8, 2001, Muppet*Vision 3D debuted as an opening day attraction at
