History Trivia / KingdomHeartsI

* DawsonCasting: Not uncommon in voice acting, but Kathryn Beaumont averted this trope when originally voicing [[WesternAnimation/AliceInWonderland Alice]] and [[WesternAnimation/PeterPan Wendy]] [[ChildrenVoicingChildren as a child]] in the 1950s. Here, she reprises her roles despite being in her mid-60s at the time. She's also one of only a few actors/actresses who worked with Creator/WaltDisney directly to be involved with the ''Kingdom Hearts'' games as well; John Fiedler, who voiced Piglet, did the role in the games as well until his death.

** Jodi Benson, who was 41 at the time, once again voiced the 16-year-old Ariel.

* TalkingToHimself: Barring a ton of examples in the English version; in the Japanese version, Donald Duck and Genie are both voiced by Creator/KoichiYamadera, along with Sebastian, Beast and Mushu.

** Squall from ''Final Fantasy VIII'' was originally designed with longer hair - and Leon's appearance here is a reference of that.

** It's rumored that Ariel was going to be a Princess of Heart originally, but they couldn't find a way to work her getting legs and captured by Maleficent after defeating Ursula - and thus was hastily replaced with Alice at the last minute. However, given that she is that world's party member, this is unlikely to have been the case.

** There was planned to be one more battle against [[spoiler:Ansem-possessed Riku]] at the End of the World. It was very nearly completed, but DummiedOut in the final version. It would have taken place on a crumbling island - which would have been a remnant of the Destiny Islands, consumed by darkness.

** On the same beat, the game’s story was originally simpler and would’ve ended with the defeat of Maleficent. However, Nomura was warned that the game wouldn’t sell well if the story wasn’t more complex, thus came the creation of Ansem and a deeper story with more twists.
** Some concept art showed SFora wearing a loincloth in the Deep Jungle and a world icon for a ''Franchise/ToyStory'' world.

* "[[RecurringRiff Destati]]" is apparently considered cursed by the production team due to odd incidents--the worst being the entire building losing power--occurring whenever the vocal track was inserted into a piece of background music.
* For the remastered version of the ''Final Mix'' re-releases, Nomura himself stated that the team had to rewrite the whole code of the game from what was available from the original since the source code was somehow lost, which lead to a ton of research, and stated that "it wasn't easy trying to recreate everything in HD from there".

** Some concept art showed Sora wearing a loincloth in the Deep Jungle and a world icon for a ''WesternAnimation/ToyStory'' world.

* ColbertBump: ''WesternAnimation/TheNightmareBeforeChristmas'' was more of a CultClassic than the money making franchise for Disney it is now until the movie being a world in the game brought it mainstream recognition.

** Disney Castle was removed as a playable world relatively late in development but its icon still appears on the world select map, unable to be interacted with by the player.

* ScrewedByTheLawyers: The reason Mickey doesn't have a major role in the game is because he was being used for Capcom's ''VideoGame/DisneysMagicalMirrorStarringMickeyMouse'', and they weren't willing to share the character rights with Square Enix. After heavy negotiation, Capcom agreed to allow Mickey in one scene as long he was in silhouette.

* For the remastered version of the ''Final Mix'' re-releases, Nomura himself stated that the team had to rewrite the whole code of the game from what was available from the original game since the original version's game data was somehow lost, which lead to a ton of research, and stated that "it wasn't easy trying to recreate everything in HD from there".

** The original scenario involved Sora saving the Princesses of Heart with the assistance of their respective princes who joined him in storming Hollow Bastion. In the end, only Beast joins Sora for his journey through the castle, while Aladdin is told he cannot join him due to the world order, and the other respective princes didn’t appear at all.
** Sora's original design was more [[LittleBitBeastly lion-like]] and wielded a [[ChainsawGood chainsaw sword]]. This was changed to a giant key to be less violent. In the games' Ultimania, WordOfGod states that the lion design for Sora was scrapped due to overlapping with the development of VideoGame/FinalFantasyIX, making him appear too similar to Zidane Tribal.

** Nomura planned for Irvine from ''VideoGame/FinalFantasyVIII'' to be part of Destiny Island's ''Final Fantasy'' trio. He couldn't come up with a design to fit the island theme, however, so he used the Wakka -- whose design is already fit for the beach setting -- instead.

*** Corey Burton instead of Joseph Kearns as the Doorknob, and Hans Conried as Captain Hook.

** Kairi being voiced by Hayden Panettierre is a borderline example. She'd had a few roles but it was right before her recognizable ones in ''Film/IcePrincess'', ''Film/RaisingHelen'' or ''Series/{{Heroes}}''.

** While some character models were massively updated for the HD remaster, other models, such as Sora and Ansem's, were instead ripped from ''VideoGame/KingdomHearts3DDreamDropDistance''.

** Kevin Michael Richardson replaces Samuel E. Wright as the voice of Sebastian, the only time the character is voiced by someone other than Wright.

* CowboyBebopAtHisComputer: Dan Birley, the author of the game's official strategy guide, stated that Sephiroth shouts an attack called "Sin Harvest". In actuality, the line is supposed to be "Descend, Heartless Angel" but the echoing voice and loud sound effects [[{{Mondegreen}} make it easy to mishear it]].

*** Yuki Tokiwa voices Pinnochio instead of Ari Hatsuzawa.

*** Creator/KoichiYamadera and Creator/TaroIshida respectively voice Sebastian and King Triton instead of Tsunehiko Kamijo and Akira Kume.
