Other mistake: After talking to his own mirror image when guarding his house from the "Heffalumps and Woozles", Pooh turns around counter-clockwise. This should mean that his mirror image would turn clockwise but it ALSO turns counter-clockwise. (00:35:55)
Continuity mistake: In Owl's house the animators have forgotten to color his umbrella among other things in the background. In a couple of shots later, they have now been colored. (00:29:20)
Continuity mistake: It's very common for the characters to misspell words or use reverse/mirrored letters. However, in Owl's house the word "hunn" (meaning hunny, the Y is just not visible) can be seen written on the jar, but in a couple of shots later it's now written as "hunny" with a reversed N. (00:29:00)
Continuity mistake: When Pooh decides to have lunch at Rabbit's house, the cutlery (a knife and a spoon) changes hands as well as disappears entirely between shots. (00:14:20)
Continuity mistake: When Christopher Robin picks up Eeyore's tail, he and Kanga are several feet away. But in the next shot they're right next to the donkey. (00:07:35)
Deliberate mistake: Several times during the movie the narrator explains what happens while the book flips its pages. During this, every page is identical to the last one so the animation has simply been copied/reused to save time and money.
Answer: Holloway could have continued voicing Winnie the Pooh, but by that time he was in his 80s and felt he could no longer effectively use his voice for the character as he once did. He chose to retire from the role.
