Jim Henson’s Muppet*Vision 3D, the last movie Henson worked on before his untimely death, first premiered at the Disney-MGM Studios (now called Disney’s Hollywood Studios) on this day in 1991. In addition to all the madness and mayhem that the Muppets have become known for, Kermit promises that, “At no time will we be stooping to any cheap 3D tricks,” before Fozzie Bear launches spring snakes out of a can toward the audience and other, well, cheap 3D tricks. Henson was a fan of the it’s a small world attraction, and if you look closely in the grand finale of the film entitled, “A Salute to All Nations But Mostly America,” you will see Muppet versions of the small world dolls and even hear a line from the song. Another interesting fact is that Waldo, “the spirit of 3D,” was Henson’s first computer-generated Muppet. Rather than traditional animation, a puppeteer would perform the movements of a puppet version of the character and the animation mimicked the movements. In 2001, Muppet*Vision 3D premiered at Disney’s California Adventure park at the Disneyland Resort.
