History Film / ShinKamenRider2023

* ActorAllusion: Before this film, Shinya Tsukamoto and Sosuke Ikematsu both appeared in the former's 2018 samurai film, ''Killing''. The story saw Tsukamoto's samurai character recruit Ikemtasu's character, a ronin who had never killed anyone before. Here, Tsukamoto plays another character who recruits an innocent young man, this time with more force; and Ikemtasu's character has to deal with the weight of having just killed several {{mooks}}.

''Shin Kamen Rider'' (''シン・仮面ライダー''), also known as ''Shin Masked Rider''[[note]]not to be confused with Saban's Series/MaskedRider[[/note]], is a ''Franchise/KamenRider'' {{Toku}}satsu film, based on [[Series/KamenRider the original series]] by Creator/ShotaroIshinomori, and created to commemorate the franchise's 50th anniversary. The film is written and directed by Creator/HideakiAnno; and casts Sosuke Ikematsu as Takeshi Hongo/Kamen Rider, Creator/MinamiHamabe as Ruriko Midorikawa, and Tasuku Emoto as Hayato Ichimonji/Kamen Rider No. 2. Additional cast include Shinya Tsukamoto, Toru Tezuka, Nanase Nishino, Yutaka Takenouchi, Takumi Saitoh, and Mirai Moriyama.

** In the original show, Tobei Tachibana was a racing coach and Kazuya Taki was an independent FBI agent, brought by circumstance to aid Takeshi Hongo and Hayato Ichimonji. Here, Tobei Tachibana is instead a Japanese government official already investigating SHOCKER and Jiro Taki his armed agent, giving them more plausible motivation and justification to cooperate with Hongo and Ruriko.

Motorcycle enthusiast Takeshi Hongo's life is irreparably destroyed when the shadowy organization SHOCKER kidnaps him and surgically alters him into a grasshopper-based augmented human being. After escaping from the organization with the help of a mysterious associate, Ruriko Midorikawa, the devastated Hongo decides to fight SHOCKER and their schemes--not as the SuperSoldier mutant known as "Batta Aug", but as a protector of humanity: "[[TitleDrop Kamen Rider]]".

''Shin Kamen Rider'' (''シン・仮面ライダー''), also known as ''Shin Masked Rider''[[note]]not to be confused with Saban's Series/MaskedRider[[/note]], is a ''Franchise/KamenRider'' {{Toku}}satsu film, based on [[Series/KamenRider the original series]] by Creator/ShotaroIshinomori, and created to commemorate the franchise's 50th anniversary. The film is written and directed by Creator/HideakiAnno; and casts Sosuke Ikematsu as Takeshi Hongo/Kamen Rider, Minami Hamabe as ally Ruriko Midorikawa, and Tasuku Emoto as Hayato Ichimonji/Kamen Rider No. 2. Additional cast include Shinya Tsukamoto as Doctor Hiroshi Midorikawa, Toru Tezuka as the Koumori Augment-01, Nanase Nishino as the Hachi Augment-01, and Mirai Moriyama as Ichiro Midorikawa.

** Both Dr. Hiroshi and Ruriko Midorikawa, instead of being merely smaller functionaries of Shocker, are in fact intimately involved with SHOCKER's current machinations. [[spoiler:Namely, the Augments and related technology are a result of Hiroshi Midorikawa's research into prana. There's also the fact that one of its highest-ranking members is in fact Ichiro Midorikawa/Kamen Rider 0, Ruriko's brother. The Midorikawas' larger involvement in SHOCKER also seems to root from their collective attempt at coping with the premature death of the family's mother, with [[DefectorFromDecadence Dr. Hiroshi and Ruriko only turning away from it pretty recently]]. Ruriko, for that matter, is in fact a computational organism, one who is augmented and connected to SHOCKER's databases and technology]]. This in turn makes it way more plausible for the both of them to release Takeshi Hongo and aid him directly in his fight against SHOCKER, even if [[spoiler:it ends with both of their deaths]].

* ArtificialHuman: During the Hachi Aug arc, [[spoiler:Ruriko Midorikawa casually reveals to Takeshi that she's a "computational organism" created by SHOCKER, meaning she has the ability to use her brain and eyes to program and re-program SHOCKER software and technology.]] SHOCKER's use of this trope is implied to earlier in the Koumori Aug arc, with [[spoiler:Koumori Aug's theater-lair being filled with what appears to be identical copies of Ruriko, all treated as Koumori's demonstration of his Bat Virus, including its capabilities of mind control and [[ExpendableClone on-command death]]]].

** Early in the film, there are hints that Ruriko Midorikawa isn't all that she seems. In the opening chase, she survives a steep fall after getting thrown off of Takeshi's bike. At the abandoned house, a desperate Takeshi grabs Ruriko by the arms, immediately stopping when he realizes he could crush her; but Ruriko is hardly pained by this. She later declares to Hongo that the only thing she and her father Hiroshi Midorikawa share is "a bit of genetic material". [[spoiler: It turns out that Ruriko herself is augmented, just like the other SHOCKER Augs. The difference is, instead of being a SuperSoldier, Ruriko is a "computational organism", [[ArtificialHuman produced from SHOCKER's artificial womb and some of Hiroshi Midorikawa's DNA]].]]

** The crossover episode of ''Anime/CrayonShinChan'' called "Shin-Kamen Rider, you know!" is also campy and comedic with Takeshi, Hayato, and Ruriko fighting together against some cartoonish-looking Augments much akin to the original show's later tone.

** In the original series, Takeshi and his allies tend to cross paths with Shocker and their plans on a per-episode basis. In this film, Hongo and Ruriko don't have information on the current Augs' whereabouts ([[spoiler:save for Ichiro's]]), but the Anti-SHOCKER Alliance is working to locate their lairs, giving the intel to the two as needed. They have already discovered the lair of Koumori Aug and possibly Sasori Aug before formally meeting Hongo and Ruriko.

* BadassLongcoat: Both Rider wear one over their body armor outside of battle, with Hongo possessing an old flayed black coat, and Ichimonji wearing a new cleaner black coat. Ruriko also possesses an inconspicuous brown one, though early promotional images show her with a shiny bright-red coat with a purple turtleneck and white boots, a nod to her original design.
