* HeyItsThatVoice:
** You may not be instantly familiar with the voice of Tony Goldwyn, but you would be familiar [[Film/{{Ghost}} with his most famous role]]. Or do you mean [[Series/{{Scandal}} President Grant]]?
** [[Series/{{Millennium}} Frank Black]] is Kerchak.
** Rosie O'Donnell as Terk.
** Professor Porter is portrayed by the late [[YesMinister Sir Nigel Hawthorne]], and Mr. Clayton is portrayed by '''BrianBlessed!!!'''
** What, no mention of {{Seinfeld}}'s Newman as Tantor the elephant?
** Creator/LanceHenriksen is Kerchak. You may also know him as Bishop from ''Film/{{Aliens}}'' and the Detective from ''Film/TheTerminator'', or Admiral Hackett from ''Franchise/MassEffect'', or the Lieutenant from ''WesternAnimation/TheLegendOfKorra''. And General Shepherd from ''VideoGame/ModernWarfare'', for that matter.
** Young Tarzan is [[DoraTheExplorer Boots]] in the sequel.
** One of the elephants in the water hole sounds like the doctor fish from ''SpongeBobSquarePants''.
** Another fun fact: PhilCollins not only sang the songs for the English version. He also did it for other 4 languages: Spanish (both Spain and Latin America, being the only Disney movie in which the songs of both versions sound the same), French, German and Italian, so people from those countries also had an unconventional HeyItsThatVoice moment.
** In the Italian dub, Terk is [[TheSimpsons Bart Simpson.]] Aside from the {{irony}} of sharing a voice actress with a character from a franchise that [[TakeThat just can't stop making fun of]] {{Disney}}, there's the fact that in the Italian dub, said voice actress (Ilaria Stagni)'s voice is ''very'' easy to recognise. Meanwhile, Tarzan is now WreckItRalph.
** In the Japanese dub:
*** Adult Tarzan is voiced by Takeshi Kaneshiro, aka [[{{Onimusha}} Akechi Samanosuke]]. He also dubs Tarzan in Chinese, since he spoke both languages, as Kaneshiro being Chinese-Japanese himself. He's [[TheOtherDarrin replaced]] by Creator/JurotaKosugi in the KingdomHearts games instead.
*** [[KenjiUtsumi Kerchak is]] [[FistOFTheNorthStar Raoh]] and [[VideoGame/MetalGearSolid3 Volgin]].[[note]]Also overlaps with HilariousInHindsight, since he's famous for voicing gorilla-sized men like the aforementioned characters. In this movie, he voices a ''literal'' gorilla![[/note]]
*** [[Creator/BanjoGinga Clayton is]] [[FistOfTheNorthStar Souther]] and [[VideoGame/MetalGearSolid Liquid Snake]].
*** [[ToshikoFujita Kala is]] [[FistOfTheNorthStar Mamiya]] and [[DigimonAdventure Taichi Yagami]].
*** [[Creator/TesshoGenda Tantor is]] [[{{Naruto}} The Nine-Tailed Fox]] and [[SengokuBasara Takeda Shingen]]
** In the Mexican Spanish dub, Adult Tarzan was voiced by the late soap opera and movie actor, Eduardo Palomo, who was casted as Tarzan because Palomo [[InkSuitActor looked helluvah lot like Tarzan]]. In fact, one of his most famous roles in a soap opera looked like as the Disney's rendition of Tarzan, ''years before'' the movie was ever conceived.
** In the Spaniard dub:
*** Kerchak is voiced by Pablo Adán, who international audiences know as [[PansLabyrinth Fauno's voice]]. However, Spanish kids recognized him at the time as [[{{WesternAnimation/Gargoyles}} Goliath's]] Spaniard voice.
*** Tarzan was voiced by Jose Luis Gil, who among many others, already played [[ToyStory Buzz Lightyear]] and a couple of years later became famous in Spain as a LiveActionTV actor in ''Aquí no hay quien viva'', a popular Spanish SitCom.
*** Terk shares her Spanish voice with [[HowIMetYourMother Robin Scherbatsky]], of all people.
*** Clayton shares his with another villain from a different Disney movie. [[Disney/BeautyAndTheBeast Maybe because they were both hunters]].
* RelationshipVoiceActor: In the Japanese dub, basically [[FistOFTheNorthStar Raoh is married with Mamiya, rather than Yuria instead, while Souther wants to kill both of them]].
* SameLanguageDub: A weird case. According to '''BrianBlessed''', although Tony Goldwyn provided the voice for Tarzan in the theatrical animated Tarzan film, Brian provided Tarzan's iconic yodel.
* ThrowItIn: The scene where Jane was ranting about what happened to her, her father and Clayton, after being rescued from the baboons? That whole thing was improvised by her voice actor, Minnie Driver.
** Likewise much of Professor Porter's reaction to her ranting was improvised along with other lines such as "Oh, just like Aunt Isabelle" when Jane describes how Tarzan walks.
