Trivia / Kamen Rider Double

  • Acting for Two:
  • Actor Allusion: Aya Sugimoto, best known as Queen Beryl, appears in The Movie Double Forever: A to Z as a Maria S Cranberry.
    • Shotaro threw an epic one in "J's Labyrinth" when he wants to enter a models-only recreation club - Renn Kiriyama is, in reality, an actor/model.
      Guard: Members only, please. This club is for models only.
      Shotaro: Haha, that's sweet. I'm a model. So, ciao.note 
    • Also in Double Forever, Elizabeth manages to recover the T2 Accel, Key, and Bird Memories, a nod to the fact that her and Queen's actresses are members of the girl group AKB48.
    • Episode 45's first two minutes are devoted to reminding us of Yuka Hirata's previous role by letting her perform her extreme tsun-tsun, extreme dere-dere schtick.
    • Yoshie Gotou, one of the Stage Moms in "The O Chain", actually appeared in Kamen Rider Kiva as the woman who went into sports archery after her own Stage Mom pushed her to learn the violin. Karma's the real bitch here.
    • At one point, Jinno notes that Takeshi would be a nice name. Also, his use of Gratuitous English mirrors his schtick as a Fake American. And the name "Catherine" pops up later... note 
    • Masayuki Deai (Trigger Dopant), though not for one of his own characters. In W Returns: Eternal, he gives the classic BoukenRed "Good job !" and thumbs up.
    • In Begins Night (W's half of Movie Wars 2010) there's this hefty Museum Mook (Giant Mook?) who jumps and attempts a Rider Punch on Soukichi. He's played by Jiro Okamoto, suit actor for Kamen Rider Black.
  • Actor Existence Failure: Minoru Tanaka, who played the villain of the Kamen Rider Accel DTV movie, committed suicide four days after the movie was released.
  • Casting Gag: The boy who Shotaro helps (and teaches the way of being hard-boiled) in the last episode is played by the same actor who played preteen Shotaro in the first episode flashback. He also plays Shotaro again in a small part of Movie War Core in the Skull section.
  • Dawson Casting: Mitsuru Matsuoka was 40 when he played Katsumi, who appears to be in his early to mid-20s based off the information given. Possibly justified since storywise he was growing up using an artificial chemical.
  • Defictionalization: Queen and Elizabeth are played by two members of idol group AKB48, and when they released their joint single "Love♡Wars", the Liar Dopant arc had them appear on an American Idol-esque contest (Fuuuuuutic Idol) performing the song in order to win a major label release.
  • Executive Meddling: 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 Law of Chromatic Superiority applies not only to several previous Kamen Riders but to Super Sentai 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 Riders 1 and 2 as their inspiration.
  • Fake Nationality: Kazu is played by Korean actor Gong Teyu.
  • Fan Nickname: Shirihiko note  and Nassca, for his butt scenes.
  • Name's the Same: There's a Nasca in the third Sgt. Frog movie. She's also an alterego (real name Miruru), with the ability to sprout wings.
    • Was the Taboo Dopant inspired by The Black Eyed Peas?
      • A pity then, that the W isn't for will.i.am...
    • And yeah. Saeko Sonozaki. Did she share a name with a certain Kamen Rider Faiz character and had a similar position for the villains?
      • Sonozaki you say? As an added bonus, Wakana was in a live-action adaptation thereof as Mion.
    • Sokichi Narumi, with the white hat and all, brings to mind a certain Sokichi Banba, better known as Big One of J.A.K.Q. Dengekitai.
    • One guest in "The F Afterglow" is an ex-thief named Fuyumi Aso, which means she may have relatives in another parallel world.
    • 'Fangs' are also tiny self-mobile weapons used by Gundam Throne Zwei and Arche Gundam.
    • There also was an Isaka in Kamen Rider Blade.
    • From "The B Carried on the Wind", Isamu Bitou, much like Isamu Ozu, had been locked away from society for some time (albeit for different reasons). It's worth noting that CycloneJokerXtreme, who debuts here, carries a sword and shield that slide together, much like Wolzard's did. He also has the same family name as Kouta Bitou, who also is friends with a guy and a girl, though in this case all three are Just Friends (close friends, but still).
    • The client from episodes 45-46 is named Kyoko Todoroki.
    • Surprisingly, Shotaro didn't freak out at the fact that his partner's true name is Raito Sonozaki.
    • The Narumi Detective Agency has absolutely nothing to do with a certain other one that deals with a certain soulless army.
    • The client in episode 49 wishes to see his sister Yui rescued. They're both someone's sister and in need of rescue constantly, but then again that's kind of a staple female role on Kamen Rider.
    • A red warrior named Ryu whose motivation is the loss of a loved one and who gets the girl at the end? Not the first time Toei's done it.
  • Old Shame: While he doesn't regret being on the show, Masaki Suda rarely talks about it and has been reluctant to reprise his role because he was Type Cast as feminine or genius characters following it, though he seems to have had a change of heart recently regarding this. In a 2017 magazine interview alongside his former co-star, he wished to be part of a "10 Years Later" special. It's implied that his agency is the reason for his lack of reappearance in the franchise.
  • Promoted Fanboy: Renn Kiriyama was a fan of Kamen Rider Black as a child.
  • Star-Making Role: It could be argued that Philip was this for Masaki Suda.
  • What Could Have Been: "The O Chain" storyline has Shroud mention CycloneAccel Xtreme, and we even get an Imagine Spot-style image of it, but it doesn't happen and probably never will because it would involve breaking up Shotaro and Philip's partnership as well as fighting with hatred rather than compassion, two things Ryu refuses to do.
    • Though we did get CAX in Kamen Rider Climax Heroes OOO.
  • Word of God: The series itself is confirmed by the staff to be a homage to the Showa Era, from the little things such as the scarf to the overall feel of the series.
