I don't recall any other actor having a voice anything like Sterling Holloway, who voice's Mr. Pooh in The Many Adventures of Winnie the Pooh. While most current viewers will recognize his voice, Mr. Holloway was a motion picture staple for over half a century, including an appearance as the fire chief in Stanley Kramer's only comedy.
I believe his first appearance in a Disney animated feature was in (Dumbo) 1941, but I may be wrong. He can be heard in Bambi (1942), in which he voiced the adult Flower, The Three Caballeros (1944), Make Mine Music (1946), Peter and the Wolf (1946), Alice in Wonderland (1951 - the Cheshire Cat), Lambert the Sheepish Lion (1952), Ben and Me (1953), The Jungle Book (1967 - Kaa, the snake), as well as The Aristocats (1970).
Many Adventures is precisely that. It's a re-edited feature of three shorts, Winnie the Pooh and the Honey Tree (1966), Winnie the Pooh and the Blustery Day (1968), and Winnie the Pooh and Tigger Too (1974). A Day for Eeyore is an added extra, along with shorts.
TMAoWtP is a terrific film for children, but will easily hold the attention of adults. The transitions, going to the pages of a book are a delight.
The Blu-ray is stunning. Unfortunately, it has gone through the typical Disney clean-up, which is inclusive of the removal of every bit of live grain. But that's an old story.
A beautiful Disney compendium of short films into a feature, and a beautifully produced Blu-ray.
