- Darkness-Induced Audience Apathy: It's a dramatization of a historical event that ended in the genocide of millions, which is clear from the start. Every major character in the film is a heinous war criminal so morally bankrupt that there's no one left to root for. The only one who somewhat maintains audience sympathy for feeling they're crossing a line is blackmailed into submission by much scarier men. It concludes with the revelation that the discussion was entirely pointless and Heydrich was going to carry out the Holocaust anyway. Finally, most of the Nazis never received any comeuppance and either died during battles or airstrikes, or more commonly, went on to live uneventful lives after the war.
- Moral Event Horizon:
Heydrich: Dead men don't hump, dead women don't get pregnant. Death is the most reliable form of sterilization - put it that way.
- The moment in the film when the rest of the cast realizes in no uncertain terms both what is to happen and the real nature of Reinhard Heydrich qualifies as a micro-one:
- Kritzinger provides an in-universe example, as he realizes that they have crossed the horizon as the attendees are departing the conference.
- Narm: The scene when Eichmann bitchslapping a younger SS soldier who is guarding the Wannsee House after compound engage in a snowball fight near the end of the conference. This scene pretends show Eichmann's cruelty but it is rather ridiculous and to some extent Eichmann is justified being angry for the guards' unprofessional conduct.
- Nightmare Fuel: Heydrich. While the film works to portray him accurately, that only makes him even more frightening. He's holding this entire meeting with the plan to kill millions of people, he has a plan for the killing, and he's PROUD of his plan. He outright brags about how many Jews his camps will kill on a daily basis like he's bragging about it like production from a factory. Summed up perfectly in this brief exchange, delivered with the most chilling smile one can imagine:
Luther: Do they [the Jews] even have a Hell?Heydrich: They do now: we provide it.
- Retroactive Recognition: Tom Hiddleston appears as an SS radio operator.
