->''"Mr. Rusk, you're not wearing your tie."''
-->-- '''Inspector Oxford'''

The penultimate film of Creator/AlfredHitchcock, ''Frenzy'' is a 1972 film adapted by Anthony Shaffer from Arthur La Bern's novel ''Goodbye Piccadilly, Farewell Leicester Square.''

Our "hero" Richard Blaney is down on his luck; just as he's fired from his job at a pub, his estranged wife Brenda is murdered by a neck-tie wielding SerialKiller. Because of a witness's mistake, Blaney is now the prime suspect. Only his former co-worker, Barbara Jane "Babs" Milligan, and his former army buddy, Johnny Porter, believe his innocence. When he's left without his allies, Richard is left to the mercy of the police. Fortunately, one investigator, Oxford, finds the smoking gun that'll save Richard from prison.

!!This film features examples of:
* AlliterativeName: Robert Rusk. There's also Brenda Blaney.
* AmicableExes: Richard and Brenda. Although they aren't all that amicable--Richard in particular is nasty and bitter. But still, Brenda offers to loan him some money.
* BadSamaritan[=/=]BigBadFriend: With nowhere else to turn, Richard hides out in Bob Rusk's apartment, whereupon Bob promptly frames him for Bob's crimes.
* BlackAndGreyMorality: The [[NominalHero hero]] is a [[ItsAllAboutMe Self-Centered]] {{Jerkass}}, while the villain is an AxCrazy, [[TheSociopath sociopathic]] [[RapeIsASpecialKindOfEvil rapist]] SerialKiller.
* BlackComedy: Some very, very dark comedy in this movie.
** Note the scene where Rusk is bouncing around in a moving potato truck, scrambling to remove his tie pin from the clutches of a corpse in rigor mortis. The potato truck takes a curve, and the corpse's foot swings up and smacks Bob in the face.
** In the opening scene, a politician's speech is interrupted by the nude body of a woman, strangled with a tie, washing up out of the river. The politician's response is "I say, that's not my club tie, is it?".
** Mrs. Oxford snapping sticks of crisp bread in two as her husband talks about how the killer had to break a corpse's fingers.
* BlackComedyRape
--> '''Solicitor in Pub''': We were just talking about the tie murderer, Maisie. You'd better watch out.\\
'''Maisie the Barmaid''': [salaciously] He rapes them first, doesn't he?\\
'''Solicitor in Pub''': Yes, I believe he does.\\
'''Doctor in Pub''': Well I suppose it's nice to know that every cloud has a silver lining.
* BlondGuysAreEvil[=/=]EvilRedhead: Rusk has carroty blond hair.
* CallingCard[=/=]WeaponOfChoice: The humble necktie.
* CatchPhrase: "You're my type of woman."
* ClearMyName: Richard is very insistent about this.
* CordonBleughChef: Given the choice between wading through grim murder scenes and tasting his wife's experimental cuisine--pig's feet, fish head soup, etc--Oxford always opts for the former.
* CreatorCameo: Hitchcock as usual, this time in the crowd looking at the body in the river.
* CruelAndUnusualDeath: Brenda's murder remains one of the most horrific, disturbing depictions of violence in film history.
* DarkerAndEdgier: Hitchcock's only film to get an R rating. This might well be because it was the first film Hitchcock made after the Production Code had been abandoned and ratings were instituted. If he could have filmed [[Film/{{Psycho}} Janet Leigh naked]] he probably would have.
* DeadMansChest: The killer hides a body in a sack that he dumps in the back of a lorry full of sacks of potatoes. He then realises that his tie pin is still clutched in the dead woman's hand and has to retrieve it from the back of the moving lorry.
* DiesWideOpen: And with tongue sticking out.
* DigitalDestruction: One reviewer of [=DVDs=] and Blu-Ray Discs received a screener copy of the ''Alfred Hitchcock: The Masterpiece Collection'' Blu-Ray set, and noticed that this movie's original opening credits sequence had disappeared in favor of one riddled with misspelled names. After his critiques on the set became widespread among film fans, Universal delayed its retail release by about one month, to correct this and other errors.
* DramaticIrony: Filled to the brim with it. A lot of it derives from the audience knowing the killer's identity.
* DrivingADesk: Very noticeable as Babs and Richard ride in a taxi.
* DropDeadGorgeous: A naked victim of the killer floats in the river in the film's first minutes.
* EnemyEatsYourLunch: Frugal or not. Bob strangles a woman to death, then picks up her apple from her desk and eats it.
* EvenBadMenLoveTheirMamas: Bob Rusk does!
* FanDisservice: This is the first and only Hitchcock film to feature nudity. Not in a very inviting context, though.
* FauxAffablyEvil: Bob Rusk, when he's not killing people.
* {{Fingore}}: One of Rusk's victims managed to grab his pin, forcing him to break her fingers to get it back. Even though she's dead, it's pretty wince-inducing.
* AGlassInTheHand: Dick does this while he's out with Brenda.
* HappilyMarried: The Oxfords despite Mrs Oxford's new hobby.
* InfoDump: A rather pointless scene where two starchy old guys at a pub chat about how TheSociopath thinks and behaves.
* {{Jerkass}}:
** Richard is such an unpleasant person that he almost deserves getting wrongfully convicted of murder. One wonders what Babs sees in him.
** His (ex-)boss at the pub, Forsythe, is a nasty piece of work as well.
* LondonTown
* TheMatchmaker: Brenda's job.
* MonsterMisogyny: Chief Inspector Oxford sums up the Necktie Killer/Bob Rusk this way, saying that serial sex-killers "hate women, and are mostly impotent." Richard Blaney himself is something of a misogynist, implied to be because of his failed relationship with Brenda.
* NominalHero: Richard is only interested in saving his own skin.
* NotHelpingYourCase: After Blaney is wrongly arrested, he acts out and ultimately escapes from prison. He returns to Rusk's apartment and beats up what he assumes to be Rusk sleeping, but it's the corpse of Rusk's newest victim. To add insult to injury, it's in front of Oxford; fortunately, Rusk shows up in a way to finally implicate himself.
* NothingIsScarier: Rusk's murder of Babs occurs offscreen.
* OhCrap: Rusk, when he's finally caught red-handed by Oxford.
* TheOner: ''Three'' of them, all pretty chilling:
** After Brenda's death, the camera stays on the street as a woman enters the building, followed by about 30 seconds of dead air until she screams, having discovered the body.
** Rusk invites Barbara into his apartment, after we already know he's the killer. The camera again remains outside, then retreats down the stairs and out of the building, where several people walk by oblivious to the murder happening right next to them.
** Blaney's trial is viewed from behind soundproof doors, with the viewer only able to hear the occasional bit of dialogue when someone opens them. They swing shut just before the sentence is read, followed by Blaney screaming "IT'S RUSK!" loudly enough to be heard through them.
* PoliceAreUseless: Subverted; Oxford is the only one to suspect Richard's innocence from the start. One of very few subversions of this in Hitchcock's work, as he was famously afraid of cops.
* RapeAsDrama: Rusk rapes his victims before murdering them.
* RunningGag: The terrible cooking of Inspector Oxford's wife.
* SerialKiller
* SexlessMarriage: It's obliquely implied that a lack of intimacy was one of the reasons the Blaney marriage failed. Richard says of Brenda's matchmaking job: "If you can't make love, sell it!"
* SignatureItemClue: Narrowly averted. A murder victim grabs Rusk's distinctive cross pin at the last minute. He notices only after dumping the body. He retrieves the pin before anyone else can find it, but the trouble he has in retrieving it creates new, albeit less definite, evidence.
* SpannerInTheWorks: Barbara steals Rusk's tiepin as he kills her; his attempt to pry it from her cold dead hands helps provide the evidence to finally send him away.
* VerbalIrony: Rusk telling Babs "You've got your whole life ahead of you" as he lures her to her death.
