The first 3D attraction at a Disney theme park was “3D Jamboree,” which premiered in the Fantasyland Theatre at Disneyland in June 1956. The attraction featured the existing 3D cartoons “Melody” (1953, released theatrically with William Castle’s 3D Western “Fort Ti”) and “Working for Peanuts” (1953, originally released with the Howard Hughes produced “Son of Sinbad,” which itself was pulled two weeks into release and rereleased in 1955 in 2D Superscope. Rumor is the film was pulled due to censorship issues. “Peanuts” was rereleased in digital 3D in 2007 with “Meet the Robinsons”) along with new 3D footage of the Mousketeers. The attraction operated through January 1964 and used twin 35mm projectors with the NaturalVision polarized process popular at the time. There would not be another 3D attraction at the Disney parks until the debut of “Magic Journeys” at EPCOT Center’s Journey Into Imagination pavilion in 1982.
