The Many Adventures of Winnie the Pooh
The movie is made from three previously released animated short movies based upon the Winnie-the-Pooh books by A. A. Milne: Winnie the Pooh and the Honey Tree (1965), Winnie the Pooh and the Blustery Day (1968), and Winnie the Pooh and Tigger Too (1974). This is also the last movie in the Disney canon that Walt Disney was personally involved with, because one of the shorts (Winnie the Pooh and the Honey Tree) was released during his lifetime, and he was involved in the production of Blustery Day. A fourth and final short movie based on the original books, Winnie the Pooh and a Day for Eeyore, was released in 1983.  It is included as a bonus feature on the VHS and DVD release of the movie.
