-->-- '''Harry Callahan'''

''Sudden Impact'' (1983) is the fourth film featuring Creator/ClintEastwood as [[Film/DirtyHarry Detective "Dirty" Harry Callahan]]. Preceded by ''Film/TheEnforcer'', followed by ''Film/TheDeadPool''.

After a number of high profile run-ins with people trying to kill him, Inspector Harry Callahan is sent to a small town to investigate the murder of a local man found dead in a car. More deaths occur, responsible for which is one Jennifer Spencer (Sondra Locke), who is out to avenge the gang-rape she and her sister were subjected to in the past.
!!This film has the examples of:

* AmusementPark: The climax takes place in a closed amusement park, also known as the Santa Cruz pier.
* AssholeVictim: Everyone Jennifer kills.
** Threlkis as well, and his hitmen who go after Harry.
* BatmanColdOpen: The film opens with Harry running into a diner robbery.
* BigBad: The rapists were an ensemble, but Mick is clearly the one calling the shots.
* BigDamnHeroes: Harry saving Jennifer from [[BigBad Mick]] and his CoDragons in the climax.
* {{Bowdlerise}}: In the TV version, the ending dialogue of the film is changed, possibly due to [[MediaWatchdog S&P]] feeling squeamish about [[spoiler: Harry letting Jennifer get away with murder]]:
** Theatrical version:
--->'''Officer Bennett:''' Inspector, we found a .38 snub in his belt. ''(shows Harry an open evidence bag; inside is the revolver Mick took from Jennifer)''\\
''({{beat}}, while Harry looks at Jennifer and she looks at him.)''\\
'''Harry''' ''(to Bennett)'': Run it through ballistics. I think you'll find [[spoiler: his gun there was used in all the killings]].\\
'''Bennett:''' Then it's over?\\
'''Harry:''' Yeah. It's over.\\
''(Harry escorts Jennifer away; camera zooms out; end of film)''
** TV version:
--->'''Harry''' ''(to Bennett)'': Run it through ballistics. I think you'll find [[spoiler: this gun there was used in all the killings]].\\
'''Bennett:''' Then it's [[spoiler: over to the jury?]]\\
'''Harry:''' Yeah. It's over.\\
''(Harry escorts Jennifer away; camera zooms out; end of film)''
* BreastAttack: One woman was involved in the gang-rape - Jennifer shoots her in the breast.
* ButForMeItWasTuesday: A number of the participants in the gang rape have no memory of Jennifer or what they did to her or her sister.
* TheCameo: '50s film star Mara Corday (an old friend of Clint Eastwood's) appears as Loretta, the waitress who overloads Harry's coffee with sugar, alerting him that something is wrong.
* CaptainErsatz: Captain Briggs is essentially Captain [=McKay=] from ''Film/TheEnforcer'' especially given that they're played by the same actor. Why they didn't just reuse [=McKay=] is anybody's guess.
* ClickHello: An armed man is sneaking up on Harry who is doing target practice, because of several threats on his life. As the man almost reaches him, Harry spins around, cocking the gun, then recognizing the man and saying "Horace!" (the man is Harry's partner).
* CoitusUninterruptus: Mick is having rough sex with a woman, and hurting her, and enjoying that it hurts her, when the phone rings. He continues to have painful (to her) sex with this woman, while on the phone, after answering the phone with an obscene response.
* ConcealmentEqualsCover: Averted in the film's climax, if only to show off how powerful Harry's [[HandCannon Auto Mag]] is. When Mick's two buddies take cover, Harry shoots through the signs and barrels they hide behind, killing them.
* DarkerAndEdgier: The film when compared to the other ''Dirty Harry'' films, due to its [[RapeAsDrama rape theme]] as well as being considered the darkest, dirtiest, and most violent of the series.
* DeceptionNoncompliance: The diner Harry Callahan goes into is being robbed, and the robbers force everybody to act normally while Callahan is there. Callahan has been getting coffee there for ten years and never has sugar, but this time, the waitress adds a ton of it. The robbers don't see anything unusual, but Callahan goes straight back in after his first sip.
* DescriptionPorn: Harry on the AMC Auto Mag:
-->"Well, this is the .44 Magnum Auto Mag and it holds a 300 grain cartridge. And if properly used, it can '''remove''' the fingerprints."
** It's not entirely clear what 'proper' technique could result in a suspect losing all of his fingers and both his thumbs, particularly considering the weapon only holds a maximum of 8+1 rounds, but no doubt Clint would find a way...
** It's a CallBack to the first film. Harry is implying that a single shot from the Auto Mag would completely destroy someone's hand.
* DepravedBisexual: Ray, the one female conspirator in the gang rape of Jennifer and her sister. She is known by all around San Paolo as a ButchLesbian, but she makes a pass at Harry, putting her in this trope.
* DisneyVillainDeath: [[BigBad Mick]], who gets shot by Harry several times with his .44 Auto Mag, sending the rapist falling off the roller coaster through a glass roof of a merry-go-round, where he is [[ImpaledWithExtremePrejudice impaled on a carved unicorn horn]].
* DramaticGunCock: One is heard in every scene which has Harry brandishing his gun.
* DramaticIrony: [[spoiler: One of the rapists, Alby Jennings, had a MyGodWhatHaveIDone moment, and tried to kill himself. As a result, he is left with brain damage and not capable of much more than staring at a wall all day, just like Jennifer's sister.]]
* DrivenToSuicide: [[spoiler: Literally, in the case of Alby Jennings, the police chief's son. After his participation in the rape, he tried to kill himself by driving headlong into a brick wall, [[{{Irony}} leaving him in a state not unlike Jennifer's sister.]] As a result of this, he winds up being the only one rapist to survive.]]
* EvilLaugh: [[DarkChick Ray]] and the entire bar she's in after Harry tells them how Wilburn died.
* {{Expy}}: Jennifer in backstory and motive is essentially a [[DistaffCounterpart female]] [[Film/DeathWish Paul Kersey]].
* FunWithAcronyms: Harry's partner Horace calls him a "jamf" twice before Harry asks him "What the hell's a 'jamf'?" Horace replies: "That means you're a Jive-Ass [[CurseCutShort Mother--]]" "Forget I asked!"
* GenderFlip: Meathead suddenly becomes a female dog in the scene where he/she alerts Harry to an intruder.
* GroinAttack: When Jennifer Spencer goes on her vendetta against the people who raped her and her sister, she shoots the rapists she tracks down in the groin before shooting them dead, [[BreastAttack except]] the one woman among them.
* HandCannon: Harry's .44 [=AutoMag=] because [[MoreDakka Caliber Size Marches On]].
* HospitalityForHeroes: The novelization of the film mentions that Harry received his unusual .44 Automag pistol as a gift from a custom gunsmith after he had saved the man's wife... probably by killing those endangering her, knowing Harry. It's suggested that he is often offered free stuff, because the text states that the pistol is the only such gift he ever accepted.
* ImpaledWithExtremePrejudice: One of the rapists gets a deliciously ironic comeuppance when he gets penetrated, by falling off the roof of the building and landing on the horn of a merry-go-round unicorn.
* KickTheDog: A literal example-Mick and Kruger's brothers-in-law injure Harry's dog after killing [[spoiler:his buddy Horace]]. It's unclear exactly what they do to the dog, but we see the poor thing limping.
* KnightOfCerebus: Due to this entry being DarkerAndEdgier, Mick is a more depraved and sadistic threat then the previous {{Big Bad}}s and the later one in [[Film/TheDeadPool the next film.]]
* LetOffByTheDetective: At the climax of the story, one of Jennifer's would-be victims holds her hostage with her own gun and Harry kills the man to save her. When the police show up to investigate, Harry shows them the gun in the man's hand and convinces them that he was responsible for all the killings.
* MeetCute: Cited in the commentary when Harry and Jennifer meet for the first time
* MolotovCocktail: Harry is being pursued by armed thugs. At one point they throw a molotov into his car, but he manages to throw it back at them.
* NoHoldsBarredBeatdown: Harry engages in a melee with Mick, Eddie, and Carl after he is ambushed by the three rapists, with Harry getting beaten and thrown into the ocean along with his .44 Magnum.
-->'''Mick:''' Hot shot cop! Your ass is mine!
* OffOnATechnicality: One perp is shown getting off easy, and later rubs it in Harry's face.
* OhCrap: When the man that raped Jennifer Spencer and his friends are about to repeat the "experience", one of them says "Crap". Cue Harry Callahan with a HandCannon, ready for the men to make his day.
* OutOfCharacterAlert: When Harry gets his usual morning coffee, the café is being robbed. Everyone is being forced to act naturally, but the waitress (knowing Harry's usual is "no sugar, no milk") adds ''lots'' of sugar. Harry, distracted by some case work he's going over, just pays and leaves with the cup. Outside, he takes a sip, spits it out and turns back to the diner.... then notices "patrons" locking the doors and turning the "Open/Closed" signs around, figures out what's up, and goes around to come in through the back.
* PreAssKickingOneLiner
-->'''Harry Callahan:''' We're not gonna let you walk outta here.\\
'''Crook:''' Who's "we", suckah!?!\\
'''Harry Callahan:''' ''(reaching for his gun)'' Smith, Wesson... and me.
* RageAgainstTheReflection: Jennifer smashes the mirror resembling the image she painted of herself.
* RapeAndRevenge: This forms the plot of the film.
* RapeAsDrama: The background of the film's plot.
* RapeIsASpecialKindOfEvil: Callahan lets Jennifer off the hook with her revenge killings of her rapists when Mick is found with the murder weapon on his person.
* RapeLeadsToInsanity: Jennifer's sister went catatonic when the two of them were gang-raped.
* RareGuns: Harry's backup gun is an AMP Auto Mag 180 (made by the designer himself from parts he had in his basement). AMP was bankrupt by the time the film was made, and very few Auto Mags were made during production.
* RasputinianDeath: Mick is first shot several times by Harry while on the Giant Dipper's catwalk, stumbles backwards through the railing, falls several stories, crashes through the roof of the moving carousel and [[ImpaledWithExtremePrejudice is impaled on a unicorn]].
* RealMenTakeItBlack: Used as a plot point. For years CowboyCop "Dirty" Harry Callahan has been ordering his coffee black and is tipped off of a robbery by his server pouring a bunch of sugar into it.
-->''"Every day for the past ten years, Loretta there's been giving me a large black coffee, today she gives me a large black coffee only it has sugar in it, a lotta sugar. I just came back to complain. Now, you boys put those guns down."''
* ReassignedToAntarctica: Harry gets sent to the main location after he [[KillingInSelfDefense kills a bunch of mobsters in self-defense]].
* RevolversAreJustBetter: Downplayed: Harry's not above settling for a semi-auto HandCannon should he lose his trusty Model 29. (Supposedly {{Enforced|Trope}} in RealLife: It's been claimed that the Auto-Mag jammed so often that they kept a diver on set to retrieve the pistol every time Clint got pissed and threw it off the pier.)
* SingleTear: Both Jennifer and her sister shed one at different points.
* SympatheticMurderer: This trope describes Jennifer Spencer-she's picking off the guys who raped her and her sister a long time ago, one at a time until she gets taken hostage by the few gang members who she has not targeted yet, but they get dispatched by Harry. When her revolver is found on the leader's body, Harry even lets Jennifer off the hook by pinning the murders on the rapist.
* TurnInYourBadge: Higher-ups try to do this to Harry after his harassment of an old mobster at his daughter's wedding results in a heart attack and they order him to take a vacation. While on vacation some punks try to take him down with a molotov cocktail and he forces them off a pier to their deaths. They end his vacation, but send him out of town on another case.
* VigilanteMan: Jennifer Spencer is a female version of this.
* VigilanteExecution: Spencer carries out quite a few of these.
* WouldHitAGirl: Harry. But she started it.
