This is from the production section on en. I would translate if I knew how but the article is locked anyway thanks to the Spider's Web: A Pig's Tale vandal.
This info is interesting:
This film was the last one to be approved by Walt Disney himself, and the first one produced after his death in 1966. The film took four years to produce, at a budget of $4,000,000. Five of Disney's legendary "Nine Old Men" worked on it, including the Disney crew that had been working 25 years on average. 126.96.36.199（討論） 2010年9月9號 (四) 23:39 (UTC)
