...that didn't happen. Here's the animation test from way back in 1983.
Later he and Glen Keane talked about how great it would be to make an animated feature where the background was computer animated, and then showed Keane the book The Brave Little Toaster by Thomas Disch, which he thought would be a good candidate for the film. Keane agreed, but first they decided to do a short test film to see how it worked out, and chose Where the Wild Things Are (a decision based on the fact that Disney had considered producing a feature based on the works of Maurice Sendak). Being satisfied with the result, Lasseter, Keane and Thomas L. Wilhite went on with the project, especially Lasseter who dedicated himself a lot to it, while Keane eventually went on to work with The Great Mouse Detective. They unknowingly stepped on some of their direct superiors' toes by circumventing them in their enthusiasm to get the project into motion. One of them, the animation administrator Ed Hansen disliked it so much that when Lasseter and Wilhite tried to sell the idea to him and Ron Miller, which they at that time were already aware of, they turned it down. A few minutes after the meeting, Lasseter was summoned by Hansen to his office, where John was told that his employment in the Walt Disney Studios had been terminated. The Brave Little Toaster would later become a 2D animated feature film directed by one of John's friends, Jerry Rees, and some of the staff of Pixar would be involved in the film alongside Lasseter.
