In 1983, future Pixar boss John Lasseter was a young animator working for Disney when he co-directed a test clip featuring a traditionally animated Max (the lead character from Maurice Sendak's classic children's book Where the Wild Things Are,) running through a 3D house that was created with CGI that was then cutting-edge. The studio rejected the technique for being too expensive... and fired Lasseter soon after!
I never knew that Mr. Lasseter had directed this during his time at Disney. Interesting bit of history.
