History Film / AHauntingInVenice

* AndTheAdventureContinues: The film ends with with Poirot accepting the case of the young man who had been begging his assistance at the start of the movie, and immediately expounding a theory about how the man's family doctor has been surreptitiously murdering the members of the family.

-->'''Ariadne''': You think the help had motive?\\
'''Poirot''': The help always have motive. Beginning with having to be called, "the help."

* ShellShockedVeteran: Dr. Ferrier reveals that [[spoiler:he helped liberate the Bergen-Belsen concentration camp. The experience and the sight of the victims has left him with some pretty intense PTSD.]]

* ColorCodedForYourConvenience: Alicia's dead body is dressed in white, symbolizing her purity and innocence. [[spoiler:Her mother's is dressed in black, symbolizing her evilness.]]

* TheWatson: As a longtime friend of Poirot's and the reason he was even at the seance at all, she serves as his assistant in solving [[spoiler:Joyce]]'s murder. [[spoiler:At least until Poirot realizes that Ariadne was working with Joyce and Poirot's bodyguard to create a "case" that would stump the great Hercule Poirot, which would give Ariadne content to write a new book on. Once her betrayal is revealed, she is treated like as much of a suspect as everyone else there.]]

* NotSoDifferentRemark: Poirot is told this by Reynolds (they're both presented with a death and come up with answers to reassure the living) and Ferrier (they're both surrounded by death).

->''"No one shall leave until I find if the living have been killed by the dead."''

* AllMythsAreTrue: While it is not do certain that the palazzo is haunted by the ghosts of dead children locked away to die by the doctors who were supposed to care for them, [[spoiler:it turns out the whole "children left to die by their caretakers" part actually is true. Their remains are found in a hidden basement beneath the house.]]

* CityOfCanals: The title and establishing shots in the trailer confirm this film will be set in the TropeCodifier city, Venice.

* KarmaHoudini: [[spoiler: Beyond their fraud plan failing and Vitale losing his position as Poirot's bodyguard neither Ariadne Oliver nor Vitale suffer any serious consequences from their attempted fraud, despite it leading to multiple deaths and gaslighting a man who was at least nominally their friend. ]] While [[spoiler:Vitale]] at least as the grace to seem ashamed of [[spoiler: his]] actions, [[spoiler: Ariadne]] is unrepentant and only upset and angry at being foiled. [[spoiler: She and Poirot even part on relatively civil if cool terms when by all rights he should have handed her over to the police.]]

* MurderByMistake. Narrowly avoided. The killer attempts to drown Poirot in the apple bobbing tub after mistaking him for Joyce Reynolds because he was wearing Joyce's cloak and mask. On realising their mistake, they release him and [[spoiler:Vitale Portfoglio]] finds him and pulls him out of the water before he can drown.

* AdaptationalJerkass: [[spoiler:Ariadne Oliver was simply Poirot's friend in canon, but here, while Poirot acknowledges her as at least some kind of friend, she takes credit for making him so famous by writing about versions of his cases and manipulates him into attending the séance just so that she can get new material for a new book]].

** The first photo is a couples' photo of Maxime and Alicia, taken during their engagement. The night of the breakup, Alicia tore the photo in half. She kept the half featuring Maxime (which is found in her room), and Maxime likewise is carrying the half of the photo with Alicia in his pocket, despite getting engaged to another woman who's very rich - a clue that he's still in love with the dead Alicia. In the background, the garden is planted entirely with [[spoiler:rhododendrons]], placing it after Joyce tore up the garden [[spoiler:and concocted a plot to keep Alicia ill and under control.]]
