The film is actually composed of material from three previously released animated featurettes based upon the Winnie-the-Pooh books by A. A. Milne: Winnie the Pooh and the Honey Tree (1966), Winnie the Pooh and the Blustery Day (1968) and Winnie the Pooh and Tigger Too! (1974). Because of this, it is seen by some as the last of the Disney "package films" (movies consisting of two or more short segments), the bulk of which were produced by the studio to keep costs down during World War II. Pooh was produced for similar economic reasons. This is also the last film in the Disney canon in which Walt Disney had personal involvement, since 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.
