I don't think it was so much a specific film as Walt's no longer working on the films. So I guess I'd say The Aristocats, but that's just because it was the first film Walt didn't work on.

We all know his death was a big part of it, and he passed right after he approved on The Aristocats. They say The Jungle Book was the last hit until The Rescuers, and that was the last hit until The Little Mermaid.
