Twice Upon a Time is a 1983 animated movie directed by John Korty and Charles Swenson. This film had an unusual history in terms of release and editing, but it has been named one of the most important films in the history of stop-motion animation. This was also the first animated film George Lucas produced. The film uses a form of cutout animation, which the filmmakers called "Lumage," that involved prefabricated cut-out plastic pieces that the animators moved on a light table. In the faraway eternally busy city of Din, live the black-and-white Rushers, who constantly go about their business in a fast-paced way and stop only to sleep. Din lies in between two worlds that create dreams to deliver to the sleeping Rushers - one is the bright and cheerful Frivoli, where Greensleeves and his Figmen of Imagination bring sweet dreams, and the other is the Murkworks, a dark and dingy factory home to vultures who drop nightmare bombs. The evil Synonamess Botch, maniacal ruler of the Murkworks wants to foil Greenie's efforts and subject the Rushers to non-stop waking nightmares. He uses his vultures to kidnap the Figs and Greensleeves, but not before Greensleeves writes an S.O.S. to Frivoli.
