 Out of the film 's 107 minutes of running time , ten of the approximately 13 minutes of animation are at the beginning of the film . Lima tried to " cram every single piece of Disney iconic imagery " that he could into the first ten minutes , which were done in traditional cel animation ( in contrast to computer @-@ generated 3 @-@ D animation ) as a tribute to past Disney fairy tale films such as Sleeping Beauty , Cinderella , and Snow White and the Seven Dwarfs . It was the first Disney film theatrically released in America to feature traditional cel animation since Pooh 's <unk> Movie ( 2005 ) . This film , although quite different in terms of plot from any previous Disney film , also contained obvious homages to other Disney films of the distant past , such as Old Yeller , The Shaggy Dog , Swiss Family Robinson , Bon Voyage ! , and Savage Sam . As most of Disney 's cel animation artists were laid off after the computer graphics boom of the late 1990s , the 13 minutes of animation were not done in @-@ house but by the independent Pasadena @-@ based company James Baxter Animation , which was started by noted lead animator James Baxter . Baxter had previously worked for Walt Disney Animation Studios , bringing to life many memorable Disney animated characters like Jessica Rabbit ( Who Framed Roger Rabbit ) , Belle ( Beauty and the Beast ) , Rafiki ( The Lion King ) , and Quasimodo ( The Hunchback of Notre Dame ) .
