History Film / GlassOnion

* ArtisticLicenseEngineering: The danger of Miles' plot to implement Klear and "turn people's home into the Hindenburg" obviously has NoOSHACompliance with regards to leakage and regulations. Moreover, the exact role of hydrogen in the destruction of UsefulNotes/TheHindenburg itself is still [[https://en.wikipedia.org/wiki/LZ_129_Hindenburg#Final_flight:_May_3–6,_1937 the subject of debate]].

* ArtisticLicenseChemistry: Klear is described as a "solid hydrogen fuel" that Miles plans to implement, powerful and dangerous enough to [[spoiler:blow up the entire Glass Onion complex]]. It's a purely fictional substance, as real hydrogen must be kept at around -435 ºF (-260 ºC) at standard temperature to keep solid. It can be stored in a solid state if bonded with other compounds like salt, but it certainly would not have the explosive properties depicted in the film.

** Speaking of the ''Mona Lisa'', Miles' speech about the perfection and beauty of the painting and framing it as the world's greatest painting would make any actual art historian laugh. The Mona Lisa was unremarkable, a commission work that some historians believe was never finished at all, until it was stolen and the theft caused a media circus that propelled it to great fame. It's appropriate that Miles, an idiot who's fame is entirely the result of image and marketing, was inspired by something unremarkable that would have languished in obscurity if not for getting a bunch of media attention.

** The court case between Andi and Miles is implied to have hinged on proving which of them came up with the original idea for the company. [[spoiler:Andi originally wrote the idea on a napkin, which she threatened to use as evidence against Miles.]] Business ideas are generally not legally protected. Control of the company would be determined by contracts and ownership of company shares. It does not matter who came up with the business plan.

* PuzzleBox: Miles Bron's invitation to his murder mystery party takes the form of elaborate-looking puzzle boxes with various layers, each being unlocked with every subsequent puzzle. Most of Bron's cohorts enjoy themselves solving it together, but Andi ([[spoiler:or rather, her twin sister, Helen]]) opts to simply put on a pair of safety goggles [[CuttingTheKnot and smash it to pieces with a hammer]]. [[spoiler:Later on, the puzzle box is brought up again [[RuleOfSymbolism as an early hint of Bron's true character]] -- while presenting as some kind of eccentric genius, not only is it not even his own work [[StealingTheCredit as he claims]] (it was commissioned), it's also not as clever as he or his fellow Disruptors think it to be (the puzzles are simple children's puzzles), and are in the end just an easily-deconstructable facade, much like how Bron himself is a thieving KnowNothingKnowItAll.]]

* NoEndorHolocaust: [[spoiler:Helen blows up the entire Glass Onion complex with Klear. The destruction is absolute, everything is on fire, and Miles' "Baby Blue" car even crashes down through the roof! Yet the Disruptors, Helen, Peg and Whiskey all conveniently survive without being maimed or killed.]]

* DeconstructedTrope: A common murder mystery set up is a rich person inviting a group of people, all of whom have a history with the host, to their estate. The guests all have a reason to wish the host harm and then, when the host dies, the rest of the mystery is finding out ''who-done-it?''. This movie instead asks the question "who is dumb enough to actually set up a situation like that?". This is possibly foreshadowing how [[spoiler:Miles is an idiot billionaire whose only idea of reasonable thought is something is stole from Benoit Blanc, the one man in the room who has any level of intelligence]].

* ChekhovsSkill: Or rather, ''lack'' of skill. [[spoiler:Miles is shown time and time again to be not nearly as smart as he appears. He frequently [[DelusionsOfEloquence misuses or makes up clever-sounding words]], his intricate mystery box is just a collection of simple children's puzzles, and even his planned murder mystery game is immediately solved by Blanc. And it turns out this extends to him as the killer: Blanc finally pins him as the guilty party once he realizes that, yes, Miles ''is'' stupid enough to murder a high-profile businesswoman he'd just had a bitter public legal dispute with.]]
