High Quality Content by WIKIPEDIA articles! Walt Disney`s Kingdom of Imagination was a movie developed by Walt Disney which never made it past pre-production. One of the best kept Disney secrets, this movie was supposedly written just before Walt Disney`s death in 1966 and was written by Walt Disney himself. The movie was supposed to be similar to that of the later The Black Cauldron, being that it was to become a fantasy epic, combining both animation with live action similar to that in Mary Poppins. It was to also feature a completely new musical score, which was never written in the end.
