[in 1967, on how he was cast as "Kaa" in Le Livre de la jungle (1967)] Walt [Walt Disney] came to me, and he's such a stickler for voices, and said, "When you're finished with what you're doing today on Winnie the Pooh, see what you can do with a snake because I can't find the right voice for it". I thought, "Wouldn't it be funny to have a snake with an aching back because it would be such a looong ache?".
