Line #3 Trivia/HeiseiRiderVsShowaRiderKamenRiderWarsFeaturingSuperSentai


1	* ActingForTwo: [[spoiler:As well as reprising his role as ZX, Shun Sugata is also serving as FakeShemp for his enemy, the Badan Empire's Ambassador Darkness. This is eventually revealed to be because ZX is ''impersonating'' Ambassador Darkness.]]
2	* CreatorBacklash: 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.
3	* 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.
4	* InMemoriam: This film is dedicated to Tohru Hirayama (producer from the original ''Series/KamenRider'' series all the way up until ''Film/KamenRiderZX'') and Takao Nagaishi (who was the director for the first decade of the franchise's Heisei era).
5	* MilestoneCelebration:
6	** 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/KamenRider555''[='=]s finale, and 5 years for ''Series/KamenRiderDecade'' and ''Series/KamenRiderDouble''.
7	** The film also seems to celebrate how there are an equal amount of primary Showa and Heisei riders, as seen with Kamen Rider Fifteen.
8	* TheOtherDarrin: Creator/TomokazuSeki voices [[spoiler: the Badan Empire's incarnation of the [[Main/HijackedByGanon Great Leader]] following the passing of his original voice actor, Creator/GoroNaya, in 2013.]]
9	* ProductionForeshadowing: We learn in the end that Murasame Ryo and Ambassador Darkness [[ActingForTwo just happen to resemble each other]] [[spoiler:because they actually are the same guy. [[Series/KamenRiderGaim Guess what we learn about Mai]] [[WhamEpisode and the Girl at the Beginning later]].]]
10	* PropRecycling: Ambassador Darkness' costume is a modification of Dai-Shocker Ambassador Hell from ''[[Film/KamenRiderDecadeAllRidersVsDaiShocker All Riders vs. Dai-Shocker]]'', with the insignia changed to Badan. It would later be used for the original Ambassador Hell in ''Film/KamenRider1''.
11	* RealitySubtext: Series/KamenRiderDenO and Daigo of ''Series/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.]]
12	* 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...
13	* 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]].
14	* WhatCouldHaveBeen
15	** This film was originally conceived as a third ''Super Hero Taisen'', with a new conflict between the Kamen Riders and Super Sentai. However, this was changed to ''Kamen Rider Taisen'' when it was recognized that the Heisei Riders were now 15, matching the Showa Riders.
16	** At one point, it was considered that the heroes from ''Series/TokumeiSentaiGobusters'' would appear.
17	** 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.
18	** 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/ResshaSentaiToqgerVsKyoryugerTheMovie'' 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.
19	** 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.
