Tom Wilhite, Disney's vice president for creative development, watched Lisberger's test footage and convinced Ron Miller to give the movie a chance. However, Disney executives were uncertain about giving $10–12 million to a first-time producer and director using techniques which, in most cases, had never been attempted. The studio agreed to finance a test reel which involved a flying disc champion throwing a rough prototype of the discs used in the film. It was a chance to mix live-action footage with back-lit animation and computer-generated visuals. It impressed the executives at Disney and they agreed to back the film. The script was subsequently re-written and re-storyboarded with the studio's input. At the time, Disney rarely hired outsiders to make films for them, and Kushner found that he and his group were given a chilly reception because they "tackled the nerve center – the animation department. They saw us as the germ from outside. We tried to enlist several Disney animators, but none came. Disney is a closed group." As a result, they hired Wang Film Productions for the animation. Because of the many special effects, Disney decided in 1981 to film "Tron" completely in 65-mm Super Panavision (except for the computer-generated layers, which were shot in VistaVision and both anamorphic 35mm and Super 35 which were used for some scenes in the "real" world and subsequently "blown up" to 65 mm). Three designers were brought in to create the look of the computer world. French comic book artist Jean Giraud (also known as Moebius) was the main set and costume designer for the film. Most of the vehicle designs (including Sark's aircraft carrier, the light cycles, the tank, and the solar sailer) were created by industrial designer Syd Mead. Peter Lloyd, a high-tech commercial artist, designed the environments. Nevertheless, these jobs often overlapped, leaving Giraud working on the solar sailer and Mead designing terrain, sets and the film's logo. The original 'Program' character design was inspired by Lisberger Studios' logo of a glowing bodybuilder hurling two discs. To create the computer animation sequences of "Tron", Disney turned to the four leading computer graphics firms of the day: Information International, Inc. of Culver City, California, who owned the Super Foonly F-1 (the fastest PDP-10 ever made and the only one of its kind); MAGI of Elmsford, New York; Robert Abel and Associates of California; and Digital Effects of New York City.
