The signature "Tarzan yell" is provided by Brian Blessed, the voice of this movie's villain Clayton. because after noticing that Tony Goldwyn could not make a convincing scream, Blessed went to one of the producers to tell him that he could do it, the producer refused at first but after he yelled in front of him, he accepted without hesitation.

To see how Tarzan's body would move while sliding down a log, the animators based his movement on that of pro skateboarder Tony Hawk while on his skateboard.

Minnie Driver largely ad-libbed the breathless speech in which Jane tells her father and Clayton about meeting Tarzan for the first time.

According to the DVD commentary, Clayton's outfit was designed to appear like Sabor's yellow fur to designate him as the new villain. When he's introduced, he's covered in shadows that give him the look of spots similar to Sabor's.

Phil Collins was chosen to provide the music as a deliberate move away from the Disney "showtune" formula.
