Where The Wild Things Are was going to be an animated film based on the 1963 book by Maurice Sendak by the same name. It was going to be directed by John Lasseter who went to work for Disney.
Disney originally owned the film rights for Where the Wild Things Are as far back as the 1980s, but they were never used.
A test sequence was animated. The backgrounds were going to be CGI and the characters were going to be traditional animated. However, due to the fact it was going to be too expensive, the film was dropped.
