The Weissmuller films made Jane (and her father) British instead of American, and later films followed suit including the Disney version, which further cemented this in viewers' minds. This resulted in many people being surprised when The Legend of Tarzan portrayed Jane as an American again. It was previously only done in Greystoke.
The Weissmuller films are also responsible for the popular image of Tarzan speaking in Hulk Speak, as well as establishing what his Signature Roar sounds like (which, in the book, is just described as "the victory cry of the bull ape").
Fair for Its Day: The books are rife with Burroughs' well-meant ethnocentricity and sexism. Burroughs repeatedly mentions the vicious and exploitative treatment the African natives received at the hands of white men, and attributes at least part of their bloodthirst to an understandable desire for revenge. He usually finds something to praise about his various ethnic characters, even if it might be in a way that would be extremely offensive today. Jane may not be an Action Girl (let's not be ridiculous!), but she's intelligent and remains level-headed no matter how dire the emergency. While later stories introduce the Waziri people and have them as subservient to Tarzan and Jane, but they are shown to be intelligent, dignified, competent, beautiful, and kind even before Tarzan met them and helped save them from exploitation; something virtually unheard of in literature at the time's portrayal of native Africans.
Hilarious in Hindsight: In 1996, a subspecies of chimpanzee has been discovered in the Bili Forest of the Congo Republic that shows many gorilla-like behaviors — much like how Burroughs' Mangani mix traits of those same apes with some primitive human. Doubles as Accidentally Correct Zoology.
Most Wonderful Sound: When Tarzan first lets loose his signature yell you know the awesomeness has only begun. The best known version from the Johnny Weissmuller films was a combination of two chorus singers and a hog caller. Intriguingly, the yell for the Disney version was provided not by Tony Goldwyn, but by BRIAN BLESSED since Goldwyn coudn't create his own satisfactory version of the yell.
The Scrappy: Cheetah is outright hated by Burroughs purists.
What Do You Mean, It's Not for Kids?: Thanks to the Disneyfied animated adaptations, the books are sometimes mistaken for being child-friendly jungle adventure stories. In reality, Burroughs' novels present a fair amount of violence, racist and sexist content, and occasionally even Gorny torture scenes.
The Disney film
Accidental Innuendo: In the song "Strangers Like Me", a lyrics goes "Why do I have/This growing need to be beside her?" Then again, the entirety of the song could be considered a metaphor for Tarzan's own romantic awakening.
Did Kerchak not accept Tarzan for so long because he was different, or because he never got over the death of his first son? Or both?
Did Terk not want Tarzan hanging around with her and the other gorilla children because she was embarrassed by him, or because she knew they didn't like him and didn't want him to feel like any more of an outcast than he already did?
The film features Disney's most complex character (at the time, anyway). Complex not just because of surface detail but because Tarzan was rendered with as much anatomical accuracy was possible. Tarzan moves like a gorilla and pulls off spectacular acrobatics and his muscles still flex and move believably. For the majority of the movie he wears very little, with his physique on full display. Not to mention the groundbreaking use of CGI for backgrounds that beautifully blended 3D movement with a classic hand painted look.
Surprisingly the MidquelTarzan II, despite being Direct-to-Video, has visuals almost interchangeable with the first.
Awesome Music: Considering that the entire soundtrack is done by Phil Collins, it's to be expected. In particular, the optimistic main theme of the film, "Two Worlds, One Family", will get stuck in your head for days.
Big-Lipped Alligator Moment: "Trashing the Camp." Other than letting Jane learn that Tarzan is part of the gorilla community, all the scene does is show off a cool scat jam written by Phil Collins. The commentary reveals that the directors considered cutting it several times, but it was a big hit with kids in the test audiences, so it was kept in.
Broken Base: As with many Disneytoons Direct-to-Video sequels, the Interquel Tarzan II is very divisive and drifts even further from the original material in favour of a standard Disney cartoon story. It is considered one of the better paced and nicely animated of the lot however. They even got Phil Collins to provide more songs. Despite its positive qualities, Disney didn't include it on the TarzanBlu-ray Disc, making Tarzan one of the few post-Lion King DAC movies of the '90s not to include a DTV spinoff on its BD.note The Hercules and Fantasia 2000 BDs don't have DTV spinoffs, either, but they didn't really receive any in the first place, aside from a Compilation Movie of episodes of the Hercules TV show.
Fanon: It's a popular notion among fans that Sabor is female, mainly because in the original novel that name was used to describe lionesses in the apes' language (male lions were referred to as Numa). The actual movie however never gives any indication of the leopard's gender, neither does the sequel or the tv series, leaving Sabor as an example of Ambiguous Gender.
It may just be a coincidence, but Tantor freaks out when a skull is bounced between his tusks in "Trashin' the Camp"; elephants are the only other animal besides humans who recognize bones.
Another one that's likely unintentional, but Tarzan has no idea what Jane is doing when she kisses him. Other species of ape do kiss, gorillas included, but protracted, romantic, mouth-to-mouth face mashing is only really seen in one other species, and that's bonobos.
Germans Love David Hasselhoff: Thanks in no small part to the fact that the hugely popular Ákos Kovács did the songs for the Hungarian dub of the movie, this film's music is immensely popular in Hungary, enough so that Ákos regularly performs them at mainstream concerts.
The stage musical had a short run on Broadway due to audiences and critics not being impressed, but in Germany it ran from 2008 to 2018, moving from Hamburg to Stuttgart and then Oberhausen.
Harsher in Hindsight: Kerchak's death has been compared to the death of Harambe, a gorilla from the Cincinnati Zoo, in 2016.
Moe: The design Disney used for Jane evokes a protective instinct - but then, this is one of literature's archetypal Damsel in Distress characters.
Tantor as a calf as well, especially since his voice actor was too young to read his lines.
Moral Event Horizon: Clayton from the Disney version crosses this when he shoots Kerchak, Tarzan's adoptive father, then, much like Gaston, tries to kill Tarzan after Tarzan spares him, resulting in a gruesome Karmic Death afterward.
No Problem with Licensed Games: The PSX/N64 game is actually really fun platformer with various difficulty settings based on the levels and it's actually quite complete. The version for GBC is also really good, having gameplay similar to that of the Donkey Kong Country games.
Obvious Judas: Was anyone really surprised when Clayton, the hunter turned out to be evil?
Older Than They Think: The combining of Kerchak and Tublat originated with the first Tarzan film in 1918.
Visual Effects of Awesome: The hand-drawn animation is beautifully blended with CGI backgrounds in several shots, some of which move in strong perspective and constantly change angles.
The Woobie: Kala. One of her first scenes involves her losing her child, she has to watch her adoptive son struggle to be accepted by the other gorillas and by her mate Kerchak, and at the end of the movie, she loses Kerchak too.
