History Trivia / JoJosBizarreAdventureDiamondIsUnbreakable

* MusicalThemeNaming: [=JoJo=] has always been known for doing this, but similarly to how ''LightNovel/PurpleHazeFeedback'' had a common naming theme of Music/JimiHendrix, ''Diamond is Unbreakable'' has a common naming theme of Music/PinkFloyd. Even Part 4's name is based on [[Music/WishYouWereHere one of their songs]]. In regards to what Stands and characters are named after Pink Floyd songs...
** Crazy Diamond: ''[[Music/WishYouWereHere Shine On You Crazy Diamond]]''
** Echoes: ''[[Music/{{Meddle}} Echoes]]'' [[DepartmentOfRedundancyDepartment (duh)]]
** Reimi Sugimoto: ''See Emily Play''
** Arnold: ''Arnold Layne''
** Atom Heart Father: ''[[Music/AtomHeartMother Atom Heart Mother (Suite)]]''

* BigNameFan: Geoff Thew of the Website/YouTube channel ''Mother's Basement'' and former writer for ''Hardcore Gamer'' was always a huge fan of ''Manga/JoJosBizarreAdventure''. However ''Diamond is Unbreakable'' is the part that he advocates for the most.

** Creator/KiraBuckland has been vocal of her love of the Jojo series, and has even campaigned to be the voice of Jolyne Cujoh when Stone Ocean is animated. But until then, she's been cast as Reimi Sugimoto.

** The anime voice actors for [[Creator/TakahiroSakurai Rohan]] and [[Creator/ToshiyukiMorikawa Kira]] both voiced Griffith in the anime adaptations of ''{{Manga/Berserk}}'' and also voiced [[VideoGame/FinalFantasyVII Cloud and Sephiroth]] respectively. Additionally, the voice actor for [[Creator/ShigeruChiba Yoshihiro Kira]] also voices [[VideoGame/DissidiaFinalFantasy Kefka]].
** Both the voice actors of Kira and Okoyasu also voice Minato Namikaze and Obito Uchiha respectively in ''Manga/{{Naruto}}'', making the time when [[spoiler: Kira temporarily kills Okoyasu]] a reversal of the fact that [[spoiler: Obito was directly responsible for Minato's death]].

* KeepCirculatingTheTapes: The Rohan Kishibe [[OriginalVideoAnimation OVAs]] have not been released on DVD or Blu-Ray in America; likely due to licensing issues or [[Administrivia/RuleOfCautiousEditingJudgement the controversy surrounding Rohan’s English VA]] Creator/VicMignogna.

* GodNeverSaidThat: Due to the following part introducing Requiem Stands, many people have stated that Yoshikage's Bites The Dust was a Requiem Stand. WordOfGod has never stated anything of that sort and instead explains it as a new power he was given by the Stand Arrow that matched what he needed. It's possible that Bites the Dust was a proto-Requiem Stand, and was probably experimenting with the concepts of evolved stands before it officially became a plot point in Part 5.

* BigNameFan: Geoff Thew of the Website/YouTube channel ''Mother's Basement'' and former writer for ''Hardcore Gamer'' was always a huge fan of ''[=JoJo's=] Bizarre Adventure''. However ''Diamond is Unbreakable'' is the part that he advocates for the most.

** ''Diamond Is Unbreakable'' is Araki's favorite part with Josuke being his favorite protagonist and Kira as his favorite antagonist. Both characters ranked #1 and #2 respectively in his Top 10 favorite characters in JOJO A-GO!GO!.

** With ''Manga/YuYuHakusho'' which ran in Manga/ShonenJump around the same time and featured a similar location, themes, and characters.

* WritingByTheSeatOfYourPants: Araki is known for this, but aside from Part 8, it's probably most apparent here. The first half of the series goes through implied [[BigBad Big Bads]] [[TheBigBadShuffle like there's a revolving door]]. Even Kira is utterly backed into a corner shortly after his introduction just like the others. As if Araki realized he should probably settle on a true BigBad by that point, Kira gets bailed out at the last possible second, allowing him to secure his place as the Part's main villain. The anime adaptation helps offset this by adding scenes that tease Kira from the very beginning.

Likewise Creator/DaisukeOno and Creator/UnshoIshizuka reprise their roles as Jotaro and Joseph for the anime.

* MemeAcknowledgement: In the English dub, Okuyasu tells Koichi "I feel you deeply" in regards to Yukako, taken from a line from the infamous Duwang scans.

* CreatorsFavoriteEpisode: Billy Kametz, the voice of Josuke in the dub, says that his favorite episode was "Let's Go Eat Some Italian Food".

* StarMakingRole: ''Creator/BillyKametz'' as Josuke. Prior to the series, he had mostly played secondary or minor characters in mobile game adaptations of various properties (such as ''VideoGame/AvengersAcademy'' and ''WesternAnimation/FamilyGuy: The Quest for Stuff''), but found himself a variety of more roles after playing Josuke.

* ShrugOfGod: The alien/human nature of Mikitaka Hazekura/Nu Mikitakazo Nshi is purposefully left ambiguous by Araki. The closest he has come to answering is to state in an artbook that Aliens are "just barely acceptable" within the [=JoJo=] fiction, without directly referring to Mikitaka himself.
