Stuck in a Pit
The storyline in this new Winnie the Pooh movie is derived from the original tales in A.A. Milne's books. The filmmakers started out with about six stories, and they used them to weave together a cohesive new adventure in the Hundred Acre Wood.
The senior story artist, Burny Mattinson, worked with Walt Disney on the original Many Adventures of Winnie the Pooh films, and it was his job to make sure the story stayed true to the original books and movies.
He worked on many films over the years of his Disney career. He helmed the award winning Mickey's Christmas Carol (one of my own Disney favorites), and he also wrote, produced and directed The Great Mouse Detective.
