The film The Aristocats was released in 1970, specifically 28 December 1970. Therefore I will presume that it was made during 1970 but there’s no guarantee that that was the case. It may have been made before then and released later but I think is reasonable to presume that it was made in 1970.
It was originally written to serve as a 2-part show in the TV series Walt Disney’s Wonderful World of Color. However, Disney wanted it made as a theatrical feature. It was the last animated film authorised by Walt Disney, himself, before his death.
