Gone is the social Darwinist worldview that underpinned the original. In the prologue we see Tarzan's parents, but we do not learn they are titled. Disney's gorillas live in a jungle uninhabited by human beings, until Europeans intrude. The Disneyfied Tarzan is such a wimp that he is not allowed to kill anything or anybody, although our Paleolithic pacifist is permitted to use martial arts techniques in self-defense. This Tarzan is a warrior for our day, when the United States refuses to send soldiers into combat because one of them might actually get hurt.
Masculine wildness is overcome by civilized femininity.
In Disney's Tarzan film, nature is feminine and civilization masculine. Tarzan is a momma's boy. When Tarzan introduces Jane to Kala, he grovels and whimpers before a disapproving Ma Gorilla. Halfway through the film, Tarzan, a Victorian-era Enkidu, lured by Jane, is prepared to follow her back to England. Although Tarzan is now nominally in control, one suspects that Kala the Ape-Mom, the Empress Dowager of the Jungle, is really in charge.
