History Film / InTheShadowOfTheMoon

* ChekhovsGun: Lock buys his wife a bracelet at the start of the movie. [[spoiler: It proves that Rya is his granddaughter.]]

* StableTimeLoop: [[spoiler:Rya eventually tells Lockhart that time travel is a one-way journey, and that nothing he can do will stop what happened in the past.]]

** Then there's [[spoiler:Naveen Rao, and his involvement in Rya's mission. Lockhart's investigation into Rya's killings in 1988 and 1997 is what attracts Rao's attention to Rya and leads him to discover her mission and support it. He thus starts developing the technology that she has used/will use on her mission]].

* ArtisticLicensePhysics: Rao's 1997 TechnoBabble explanation of how the supermoon's gravity interacts with "electromagnetic pockets" to enable [[spoiler:TimeTravel]] makes no scientific sense in the world of physics as we know it today.

* BaldHeadOfToughness: The killer, [[spoiler:Rya]], is a woman and her head is entirely shaved. She's a very capable opponent, showing great strength and speed and some MadeOfIron tendencies, like shaking off a bullet lodged in her leg.

* BaldHeadOfToughness: The killer, [[spoiler:Rya]], is a woman and her head is entirely shaved. She's a very capable opponent, showing great strength and speed.

* BaldWoman: The killer, [[spoiler:Rya]], is a woman and her head is entirely shaved.

!!This film contains examples of:

* DeadPartner: Double-Subverted. Rya injures Maddox in the first killing spree, and when she sees Lockhart a bit later she apologizes about his partner. Maddox survives though, although he's left with a limp. [[spoiler: Until 1997, anyway, when chronologically Rya met him earlier and he does die]].
* DeathByChildbirth: As Lock has his first run in with the killer, his wife goes into labor. He has enough time to kiss his wife and be by her side before she dies of a hemorrhage.
* DividedStatesOfAmerica: [[spoiler: Implied by the ending narration, when Rya explains that the Real American Movement's attack eventually leads to civil war. This is why she time-travels, to prevent it.]]
* {{Foreshadowing}}:

** In the first minute of the movie, we see [[spoiler:the flag of the militia. So, when we hear about the militia and see that same flag later on, we know they have something to do with the future.]]

* LongLostRelative: [[spoiler:Rya]] is mixed race, with a Black father and White mother. This allows the reveal of her being [[spoiler:Lockhart]]'s granddaughter to be a surprise, since he's White (his daughter was her mother).
* LudicrousGibs:

* ObnoxiousInLaws: An interesting case where this applies to the hero. Lockhart starts out as just an eager beat cop running around crime scenes and getting in the way of his brother in-law Detective Holt, while ignoring his requests to stop. As the case progresses and Lockhart gets obsessed with the case and being MistakenForCrazy, he begins haranguing Holt for various forms of support that he never gets.

* RightWingMilitiaFanatic: As he investigates the links between the murder victims, Lock finds that they were all members of the "Real American Movement". [[spoiler: They're the ones responsible for launching a second civil war in 2024.]]

* SetRightWhatOnceWentWrong: [[spoiler: This turns out to Rya's mission-preventing a future civil war by killing people in the past who helped instigate or wage it.]]

* StableTimeLoop: [[spoiler: Rya eventually tells Lock that time travel is a one-way journey, and that nothing he can do will stop what happened in the past.]]
** A more explicit example is [[spoiler: the airplane keys. In 1988, the police find a mysterious set of keys on Rya's corpse. In 1997, Locke learns that they are the keys to a plane at a nearby airfield, which leads him to go there. An earlier version of Rya happens to be hiding out there, and in a bid to escape, she takes the keys to the plane. Thus, the keys only end up in Rya's possession in the first place because they were found on the corpse of her future self.]]
** Then there's [[spoiler: Naveen Rao, and his involvement in Rya's mission. Locke's investigation into Rya's killings in 1988 and 1997 is what attracts Rao's attention to Rya and leads him to discover her mission and support it. He thus starts developing the technology that she has used/will use on her mission.]]
* TimeTravel / SetRightWhatOnceWentWrong: What Lock eventually realizes the killer is doing. [[spoiler:He's also the one who convinced her to do it.]]
* TomatoSurprise: [[spoiler: Lock was the one who told Rya to travel back in time and stop the civil war from starting in the first place.]]

* WalkingSpoiler: [[spoiler: Any mention of Rya and her goal.]]

* WesternTerrorists: The Real American Movement go several steps beyond being just one [[RightWingMilitiaFanatic right-wing militia]] of many when they [[spoiler:launch simultaneous inner-city bombings that kill a combined 11,000 people and eventually trigger a second American civil war that would lead to millions more dead]].

* YouHaveToBelieveMe: both Lockhart and Rao have their moments. Averted with Rya, who makes her case more calmly, and with a faint smile, while speaking more persuasively.

* HybridAllAlong: [[spoiler:Rya]] is mixed race, with a Black father and White mother. This allows the reveal of her being [[spoiler:Lockhart]]'s granddaughter to be a surprise, since he's White (his daughter was her mother).

* MixedAncestry: [[spoiler:Rya]] is mixed race, with a Black father and White mother. This allows the reveal of her being [[spoiler:Lockhart]]'s granddaughter to be a surprise, since he's White (his daughter was her mother).

* RippedFromTheHeadlines: The film was made in 2019 at the height of the UsefulNotes/BlackLivesMatter movement, making the scenes of Philly residents protesting PoliceBrutality against citizens of color feel very non-fictional.

* PronounTrouble: [[spoiler: Rya refers to her grandfather as "Tom" to keep the audience from knowing the connection too early.]]
* OffingTheOffspring: [[spoiler:Lockhart accidentally kills Rya in 1988, not knowing she's his granddaughter. He only learns this 27 years later, much to his horror.]]
* ObnoxiousInLaws: An interesting case where this applies to the hero. Lockhart starts out as just an eager beat cop running around crime scenes and getting in the way of his brother in-law Detective Holt, while ignoring his requests to stop. As the case progresses and Lockhart gets obsessed with the case and being MistakenForCrazy, he begins haranguing Holt for various forms of support that he never gets.

* BlackBestFriend: Maddox is obviously this to Lockhart.

* AccidentalAimingSkills: In 1997, [[spoiler:Rya]]'s hasty reaction shot with a shotgun at someone behind her results in her AccidentalMurder of [[spoiler:Maddox]].

* WiseBeyondTheirYears: Nine-year-old Amy, whose EstablishingCharacterMoment is getting up and making breakfast for herself and her dad.

* ParentalNeglect: Lockhart is so obsessed with the killer that he almost misses his daughter's birth, screws up her 9th birthday by working till late into the night (he even makes her help him out at the precinct), and generally makes a mess of their relationship until she's about to have her first kid herself at the age of 27.
