* CompleteMonster: In the live-action adaptation of Creator/PhilipKDick's AlternateHistory [[Literature/TheManInTheHighCastle novel]], Oberstgruppenfuehrer [[HistoricalDomainCharacter Reinhard Heydrich]] is the second-in-command of the SS, the [[StateSec paramilitary organ]] in charge of enforcing UsefulNotes/NaziGermany's racial ideology. He organized the [[UsefulNotes/TheHolocaust total genocide of the Jews within Europe and Nazi-occupied America]] and participated in the enslavement of the entire African continent, boasting of having personally hunted down "tribal subhumanoids." Heydrich's faction is opposed to UsefulNotes/AdolfHitler's policy of détente with the Empire of Japan, wanting to exterminate the Japanese so the Nazis can [[TakeOverTheWorld have the entire world for themselves]]. He arranges a public assassination of the visiting Japanese Crown Prince in an attempt to provoke the Empire into declaring war. When [[TheAtoner remorseful]] Nazi spy Rudolph Wegener passes on nuclear technology to his Japanese contacts to preserve peace, Heydrich flies to New York City to retrieve Wegener. He makes it clear that the only reason he hasn't already had Wegener tortured to death for high treason is because he needs him for his access to the Fuehrer, threatening to [[IWillPunishYourFriendForYourFailure have Wegener's family murdered if he doesn't comply]]. Heydrich wants to assassinate Hitler so he can [[TheStarscream take over the Reich]] and destroy the Japanese Home Islands with [[NukeEm nuclear missiles]], mocking loyalty as a weakness that greater men lack. When Obergruppenfuehrer John Smith discovers Heydrich's scheme, he invites Smith to a hunting party so he can [[HuntingAccident have him quietly killed]]. [[TheDreaded Feared even by his fellow Nazis]] as the Reich's foremost hatchet man and expert in mass murder, Heydrich enjoys every part of what he does and is known as [[RedBaron "The Man with the Iron Heart"]], a title he admits to wearing with pride.
** The name of the German-occupied "Greater Nazi Reich" doesn't really make sense. "Nazi" was a German colloquial abbrevation of "national socialist" and was [[https://en.wikipedia.org/wiki/Nazism#Etymology never officially in use during the period of the Nazi rule in Germany]] - officially naming a state like that would have been like officially calling the USA "United Yank States" or the USSR "Commie Union of Russia".
** In the TV show: as in the book, characters whose surnames are traditionally associated with Jewish heritage change their names to avoid persecution, even if they aren't actually of Jewish descent and/or don't personally identify as Jewish, with Frank Frink (originally Frank ''Fink'') a prominent example discussed in-universe. So how the heck is no-one talking about the fact that the Obergruppenführer's son is being treated by a doctor named ''Adler''?
* CultClassic: In the alternate history fandom.
* GeniusBonus: In "Revelations", it is shown that the secret "Baynes" tries to get over [[spoiler:are nuclear fusion formulas.]]
* FollowTheLeader: The first few editions of the book had covers with a rising sun and a swastika side-by-side, sometimes dividing a map of the United States in half. Simple, direct, and to the point, right? But in the late 80s, after the release of the CultClassic PKD adaptation ''Film/BladeRunner'', all of a sudden we get '''''[[http://www.audioeditions.com/audio-book-images/l/The-Man-in-the-High-Castle-310626.jpg this]]'''''. Although the book mentions that [[StupidJetpackHitler Nazi technology in rocketry has advanced]], nothing in the book even remotely suggests the San Fransisco of this alternate universe is the kind of cyberpunk metropolis ''Blade Runner'' popularized. In fact, when Tagomi [[spoiler: crosses over to our world]], it's suggested the San Fran of the book is even ''less'' industrialized.
* HilariousInHindsight: The way the Japanese fawn over the tritest American kitsch in the book is funnier now, after the rise of anime and manga fandom in the United States, some members of which do the exact same thing to Japanese culture.
* NauseaFuel: The Nazi doctors inventing new uses for dead bodies, such as using the joint of the big toe as a mechanism for a lighter.
