History Trivia / KamenRiderDouble

* NamesTheSame: There's a Nasca in the third KeroroGunsou movie. [[spoiler:She's ''also'' an alterego (real name Miruru), with the ability to sprout wings]].

** The Narumi Detective Agency has absolutely nothing to do with [[RaidouKuzunohaVsTheSoullessArmy a certain other one that deals with a certain soulless army.]]

** Yoshie Gotou, one of the Stage Moms in "The O Chain", actually appeared in Series/KamenRiderKiva as the woman who went into sports archery after her own StageMom pushed her to learn the violin. Karma's the real bitch here.

** In ''Begins Night'' (W's half of ''Movie Wars 2010'') there's this hefty Museum {{Mook}} (GiantMook?) who jumps and attempts a Rider Punch on Soukichi. He's played by Jiro Okamoto, suit actor for KamenRiderBlack.

* HeyItsThatGuy:
** ''Double'' is packed with ''Franchise/SuperSentai'' alumni:
*** Lunagel from ''Series/MahouSentaiMagiranger'' (Meibi Yamanouchi) is Marina in "The W Search".
*** [[spoiler:Kirihiko's little sister Yukie]]/Yuko in "Y's Tragedy" is Kaoru Hirata, who played Yuka Yamazaki, also in ''Series/MahouSentaiMagiranger''.
*** The human form of Arms Dopant? That's [[Series/BakuryuuSentaiAbaranger [=AbaRed=]]] (Kouichirou Nishi). As if to push the point further, he states repeatedly that he loves to "rampage"[[note]]"''Abare''"[[/note]]. And on top of that, Shotaro and Philip fight him with what is basically the Double equivalent of Abarekiller, [[TheSpiny spines]] and all.
*** "''[[strike:[[Series/TokusouSentaiDekaranger Jasmine]]]] Aya (Ayumi Kinoshita) wa [[strike:[=ESPer=]]] [[HilariousInHindsight Deka]] [[TheNarrator de aru]].''"
*** And [[Series/NinpuuSentaiHurricaneger [=HurricaneBlue=]]] (Nao Nagasawa) appears in "The D was Seen" as Lily Shirogane, a stage magician who uses a Dopant Memory to cheat at her disappearing act. She would return in the Accel edition of ''Kamen Rider Double Returns'' as a [[AscendedExtra waitress]] at her grandfather's coffee shop. She is still a magician, though, and even manages to [[spoiler:allow Shotaro and Philip to escape police custody via her Memory-free vanishing act so they can assist Accel]].
*** We have Naoki Kawano and Yuka Hirata from ''Series/JukenSentaiGekiranger'' appearing as Toru Kawai and Kyoko Todoroki in episodes 39 and 45 respectively. They previously appeared as the BigBad Long and DarkActionGirl Mele.
*** [[Series/GoGoSentaiBoukenger BoukenSilver]] (Masayuki Deai) played the Trigger Dopant in ''Double Forever''.
*** [[Series/SamuraiSentaiShinkenger Rin Takanashi (Mako Shiraishi/Shinken Pink)]] and [[Series/BakuryuuSentaiAbaranger Sho Tomita (Yukito Sanjou/Abare Blue)]] appear in the Kamen Rider Eternal edition of ''Kamen Rider Double Returns'' alongside Jyunichi Haruta ([[Series/DaiSentaiGoggleFive Goggle Black]] & [[Series/KagakuSentaiDynaman Dyna Black]]).
*** While not a Sentai alumni at the time, [[Series/KaizokuSentaiGokaiger GokaiPink]] appears in episode 49.
** Some ''Franchise/KamenRider'' alumni, too:
*** Amane Kurihara from ''Series/KamenRiderBlade'' (Hikari Kajiwara) shows up in "The Vengeful V" as one of the art students.
*** The actor playing the human form of the [[spoiler:Liar]] Dopant was in ''Series/KamenRiderKabuto'', playing a surgeon that rotated his duties with two Worms mimicking him.
*** Kirihiko showed up way back in the first two episode of ''[[Series/KamenRiderDenO Den-O]]'' as one of the bullies who harassed Ryotaro.
** Of all the Japanese comedians who get bit parts in this show, the human form of Cockroach Dopant is a member of the comedy group ''Rahmens'', best known for his role as "Persocom" from the Japanese ''[[http://www.youtube.com/watch?v=qnzmXD2YTqc Mac and PC]]'' commercials.
** The teacher from "Find the C" which accosts the DanceBattler Dango could very well help Double with his crime-solving exploits as he is, after all, [[Series/JikuuSenshiSpielban a retired Metal Hero]].
** One of [[ThoseTwoGuys Those Two Girls]] from ''MadanSenkiRyukendo'' (either Ichiko or Ritsuko) appears in episode 9.
** The human form of the Sweets Dopant was in the J-Dramedy ''Shomuni: Power Office Girls''.
** Watcherman, the "Otaku blogger with a FunnyAfro". There is a funny thing about that, it's [[ActorAllusion not the first time that he has been]] [[Franchise/TrainMan an Otaku]]. The FunnyAfro was the dead giveaway.
*** And with him is the human actor to the Money Dopant, [[Franchise/TrainMan the worldly travelling]] one asking for the details in the live-drama... that's Money.
*** Watcherman's actor, Nasubi, is also well-known for being one of the first RealityTelevision stars ever.
** [[http://en.wikipedia.org/wiki/Ichirou_Mizuki Aniki!]]
** TomoyukiDan plays Dr. Isaka on-screen, meaning [[Anime/MobileSuitVictoryGundam Chronicle Asher]] is the Weatherman!
** Himeka from the "The Nightmarish H" and Nagisa from the "Beyond R" are both alumni from the ''MahouSenseiNegima'' live action series.
** Also appearing in ''Double Forever'' is Aya Sugimoto (see ActorAllusion above).
*** Speaking of ''[[Series/PrettyGuardianSailorMoon PGSM]]'', Miyuu Sawai, a.k.a. Sailor Moon herself, made an appearance in ''Begins Night'' as a pop idol who had died a year before, and whose supposed ghost has been appearing to her sister.
** [[Series/PowerRangersDinoThunder "Mr O'Shaughnessy"]] cameos in ''W Returns: Accel'' [[spoiler:as a PosthumousCharacter in flashbacks]].
* HeyItsThatVoice: Creator/FumihikoTachiki is both TheNarrator and the voiceover of the Gaia Memories, and by extension, the Double Driver.
** Mikio Jinno is played by Takeshi Nadagi, one half of the duo Dylan & Catherine, best known for performing the ''KeroroGunsou'' theme song "Fundari Kettari". Almost counts as a HeyItsThatGuy with Nadagi's InkSuitActor [[http://www.youtube.com/watch?v=qNhCM7VfvCE in the title sequence.]]
*** [[http://www.youtube.com/watch?v=yWL_ZOkJ6Oo&feature=related How about now?]]

** Mick is the [[LolCats Cheezburger Dopant]]

*** [[HigurashiNoNakuKoroNi Sonozaki]] you say? As an added bonus, Wakana was in a live-action adaptation thereof as Mion.

** Surprisingly, Shotaro, GenreSavvy that he is, didn't freak out at the fact that his partner's true name is [[spoiler: [[Manga/DeathNote Raito]] [[HigurashiNoNakuKoroNi Sonozaki]]]].

** Watcherman, the "Otaku blogger with a FunnyAfro". There is a funny thing about that, it's [[ActorAllusion not the first time that he has been]] [[DenshaOtoko an Otaku]]. The FunnyAfro was the dead giveaway.
*** And with him is the human actor to the Money Dopant, [[DenshaOtoko the worldly travelling]] one asking for the details in the live-drama... that's Money.

** Shotaro threw an epic one in "J's Labyrinth" when he wants to enter a models-only recreation club.

* ActorAllusion: Aya Sugimoto, best known as [[PrettyGuardianSailorMoon Queen Beryl]], appears in TheMovie ''Double Forever: A to Z'' as a Maria S Cran'''berry'''.

*** Speaking of ''[[PrettyGuardianSailorMoon PGSM]]'', Miyuu Sawai, a.k.a. Sailor Moon herself, made an appearance in ''Begins Night'' as a pop idol who had died a year before, and whose supposed ghost has been appearing to her sister.

* NamesTheSame: The show's songs have this, but they're named after some Disney songs: ''Nobody's Perfect'' and ''Naturally''. The former song has two: One of a upbeat song sung by HannahMontana, the other is a gloomy one by Koji Kikkawa. The latter one: One's an upbeat song by SelenaGomez (and the Scene), the other sung by Wakana Sonozaki. Double points: It helps that Avex, the one making songs for the Franchise/KamenRider Franchise since 2001, distributes The Walt Disney Records/Hollywood Records label in Japan, so the titles are (maybe) coincidence.

* While fans have been clammoring for [=FangMetal=] or [=FangTrigger=] since the Fang Memory debuted, the Double novel explains why these forms can't ever be used. While the Fang Memory normally turns Philip into TheBerserker, Shotaro's compatibility with the Joker Memory allows him to keep this in check, rendering [=FangJoker=] stable. Shotaro has no special compatibility with the Metal and Trigger Memories, meaning those forms couldn't be controlled.

* HeyItsThatVoice: FumihikoTachiki is both TheNarrator and the voiceover of the Gaia Memories, and by extension, the Double Driver.

* ExecutiveMeddling: {{Averted}}; the show's staff said that there was incredible pressure from Toei to make Double's primary color red (which is viewed as a heroic color in Japan, and is the reason the LawOfChromaticSuperiority applies not only to [[KamenRiderKuuga several]] [[KamenRiderRyuki previous]] [[KamenRiderKabuto Kamen]] [[KamenRiderDenO Riders]] but to Franchise/SuperSentai as well). They apparently had to fight long and hard to avoid this, and only managed to get black and green as Double's default form by citing [[Series/KamenRider Riders 1 and 2]] as their inspiration.

** Some ''KamenRider'' alumni, too:
*** Amane Kurihara from ''KamenRiderBlade'' (Hikari Kajiwara) shows up in "The Vengeful V" as one of the art students.
*** The actor playing the human form of the [[spoiler:Liar]] Dopant was in ''KamenRiderKabuto'', playing a surgeon that rotated his duties with two Worms mimicking him.

* ExecutiveMeddling: {{Averted}}; the show's staff said that there was incredible pressure from Toei to make Double's primary color red (which is viewed as a heroic color in Japan, and is the reason the LawOfChromaticSuperiority applies not only to the last few Kamen Riders but to SuperSentai as well). They apparently had to fight long and hard to avoid this, and only managed to get black and green as Double's default form by citing [[Series/KamenRider Riders 1 and 2]] as their inspiration.
