History Trivia / HeiseiRiderVsShowaRiderKamenRiderWarsFeaturingSuperSentai

* OldShame: Hiroshi Fujioka was ''not'' happy with how he was portrayed here. So much so that he helped with rewrites in 2016 film ''Film/KamenRiderIchigo'' to get his character right.

** The Kyoryuger Ressha, which was part of a ''[=ToQger=]'' Legend Sentai line going back to ''[[Series/EngineSentaiGoOnger Go-Onger]]'', was planned to appear in ''Film/ResshaSentaiTokkyugerVsKyoryugerTheMovie'' before Shinichiro Shirakura brought it forward to ''Kamen Rider Taisen''. The Kyoryuger Ressha ultimately did appear in ''vs. Kyoryuger'' but as a miniature [=ToQ=] Ressha rather than a HumongousMecha, being used in the [=ToQger's=] [[{{BFG}} Renketsu Bazooka]] for a new FinishingMove.

** This film commemorates the following celebrations for the franchise -- 40 years for ''Series/KamenRiderX'', 35 years for ''Series/KamenRiderSkyrider'', 30 years for ''Film/KamenRiderZX'', 25 years since ''Series/KamenRiderBlackRX''[='=]s finale, 20 years for ''Film/KamenRiderJ'', 15 years for ''Series/KamenRiderKuuga'', 10 years since ''Series/KamenRiderFaiz''[='=]s finale, and 5 years for ''Series/KamenRiderDecade'' and ''Series/KamenRiderDouble''.

** On a minor note, a promotional image for the movie shows Fifteen Gaim Arms wielding Gaim's Musou Saber in addition to the Daidaimaru. In the final cut, however, he [[DualWielding dual-wields]] the Daidaimaru with his own Yomimaru instead.

** The Kyoryuger Ressha, which was part of a ''[=ToQger=]'' Legend Sentai line going back to ''[[Series/EngineSentaiGoOnger Go-Onger]]'', was planned to appear in ''Film/ResshaSentaiTokkyugerVsKyoryugerTheMovie'' before Shinichiro Shirakura brought it forward to ''Kamen Rider Taisen''. The Kyoryuger Ressha ultimately did appear in ''vs. Kyoryuger'' but as a miniature [=ToQ=] Ressha rather than a HumongousMecha, being used in the [=ToQger's=] [[{{BFG}} Renketsu Bazooka]] for a new FinishingMove.

** An initial design for Gaim's #1 Arms was more in line with the other Legend Riders, having its chest be based on Rider 1's own Converter Lung before it was decided to shape the chest after the helmet's faceplate

** At one point, it was considered that the heroes from ''Series/TokumeiSentaiGobusters'' would appear.

* NamesTheSame:
** This movie features three Ichigos -- Kamen Rider ''#1'', Gaim ''Strawberry'' Arms, and Toq ''#1''. ''Ichi'' and ''Go'' by themselves is 1 and 5, put it together and you get the number of Showa Riders and Heisei Riders facing off. Acknowledged when the [[Series/ResshaSentaiToQger [=ToQgers=]]] show up and Raito offers to lend his power to Hongo as a "fellow #1"
** Keisuke's granddaughter is named Mari, which presumably rubs a sore spot with Takumi for very good reasons.
** When Tsukasa goes to Fuuto, Kaito Kumon offers to go with him. This isn't the first time Tsukasa has worked alongside a {{Jerkass}} named [[PhantomThief Kaito]]...

* RoleReprise: In addition to the contemporary casts of ''Series/KamenRiderGaim'' and ''Series/ResshaSentaiToQger'', there's ''Series/KamenRiderWizard'', one half of ''Series/KamenRiderDouble'', ''Series/KamenRiderDecade'', ''Series/KamenRider555'', ''Film/KamenRiderZX'', ''Series/KamenRiderX'', [[Series/KamenRider Takeshi Hongo]] and [[Series/ZyudenSentaiKyoryuger Kyoryu Red]].

* RecycledScript: The reason why the Riders are killing each other being because [[spoiler:"dying" actually sends them to another dimension, alive and well, so that the villains think the heroes are all dead and then bring out their super-weapon into the open, unaware of the BigDamnHeroes incoming from the few survivors opening up that dimension]]... looks like Hongo directly ripped some pages off Tsukasa (and Captain Marvelous) during the events of ''Film/KamenRiderXSuperSentaiSuperheroTaisen''. Well, that's ''half'' the reason why...

* DyeingForYourArt: In his blog post, Kento Handa remarked that he had to dye his hair in order to play Takumi Inui...a role he originated ten years ago.
* InMemoriam: Dedicated to Tohru Hirayama (producer from the original series to ''ZX'') and Takao Nagaishi (director for the first decade of the Heisei era).
* MilestoneCelebration: Here we go:
** 40 years for ''Kamen Rider X''
** 35 years for ''Skyrider''
** 30 years for ''Kamen Rider ZX''
** 25 years since ''Kamen Rider Black RX'' ended.
** 20 years for ''Kamen Rider J''
** 15 years for ''Kamen Rider Kuuga''
** 10 years since ''Kamen Rider Faiz'' ended.
** and 5 years for ''Kamen Rider Decade'' and ''Double''. WHEW!
** It also seems to celebrate how there are now an equal amount of primary Showa and Heisei riders, as seen with Kamen Rider Fifteen.

* RealitySubtext: KamenRiderDenO and Daigo of ''ZyudenSentaiKyoryuger'' have both been accused of being the SpotlightStealingSquad (Daigo within his own show at least, while Den-O has had one movie or cameo after another). So what happens when they're in the same movie? [[DoesThisRemindYouOfAnything Argue over who gets to be on top, of course.]] [[LeaderFormsTheHead The combined mecha, that is.]]
