One of the most infamous {{Mind Screw}}s in film history, directed by Donald Cammell and Nicolas Roeg. Also famous as the first acting role for Music/MickJagger.

LondonGangster Chas (James Fox) is the lead enforcer for [[TheDon Don]] Harry Flowers. When he seriously pisses Flowers off by killing an old enemy of his who Flowers would have preferred to come to a profitable arrangement with, he is left desperate for a place to hide before he can get a fake passport and leave the country. He inveigles himself into the crumbling townhouse that burned-out rock star Turner (Jagger) shares with his two girlfriends: witchy German Ferber (Anita Pallenberg) and sunny French Lucy (Michèle Breton). He gradually finds himself drawn into their life of heavy drugs and weird sex. And then things get '''really''' peculiar...

A legendary CultClassic since its release, ''Performance'' stands out as even among the more weird films made in the period, subject to rumours and speculations even during production. The nudity and sex scenes earned it the ire of Warner Bros who had produced the film, resulting in early bowdlerized versions. The film has since been regarded and treasured as a defining portrait of London in TheSixties, for its GenreBusting KudzuPlot. The film's score by Jack Nitzche is highly praised and the song "Memo from Turner" by Ry Cooder and Mick Jagger is well regarded enough that Creator/MartinScorsese recycled it for ''Film/{{Goodfellas}}''. Another BigNameFan Creator/AlanMoore devoted an entire section of his ''ComicBook/TheLeagueOfExtraordinaryGentlemen'' comics to making an unofficial prequel to some of the events in the film, with the SerialNumbersFiledOff of character names.

!!This film provides examples of:

* AdamWesting: Ferber the mysterious, bisexual drug addict girlfriend of a rock star, was played by Anita Pallenberg, a mysterious bisexual who was struggling with a heroin addiction and dating a rock star at the time.
* BigFancyHouse: The main setting
* ConceptVideo: The fantasy sequence in which Turner, adopting Chas's LondonGangster persona, sings the song "Memo From Turner" to Flowers' gang. This was actually released as a pop video separately to the film. Also counts as a SanitySlippageSong.
* CoolCar: Chas's Jaguar Mark II, and Flowers' Roller.
* CreepyChild: Lorraine, the weird little girl with a false moustache who drifts in and out of Turner's house. Is she his daughter? Related to one of the women? A street urchin who talked her way in like Chas? Something outright sinister?
* DontMakeMeTakeMyBeltOff: Joey savagely beats Chas with a belt before Chas gets free and kills him.
* ExactEavesdropping: The conversation Chas overhears at Paddington station that alerts him to Turner's free room.
* FourTemperamentEnsemble:
** Sanguine: Lorraine
** Choleric: Chas
** Melancholic: Turner and Ferber
** Phlegmatic: Lucy
* ForeignPeopleAreSexy: Ferber and Lucy
* GainaxEnding: A well-known one. [[spoiler:As Flowers' hoods turn up at the house, Chas shoots a passive and maybe willing Turner dead, then peacefully surrenders to them. As he is driven off in a white Rolls-Royce, presumably to his death, we see him look out of the window, and his face appears to be Turner's.]]
* {{Gayngster}}: What initially is heavy homoerotic innuendo about Flowers and his gang is then made full text when we see that he and one of his inner circle share a bedroom.
* GenreShift: For the first half-hour or so, it's a gritty, violent (if artily directed) gangster movie. Then Chas turns up at Turner's house and everything gets weird.
* InterplayOfSexAndViolence: In the early part of the film, there are several bits where gangster violence gets intercut with sex scenes between Chas and his girlfriend, and between Turner and his girls.
* LondonGangster: Lots and lots of them. Some of the minor gangster characters were reputedly [[CastTheExpert the real thing]].
* MentalFusion: Ends up happening between Chas and Turner. Maybe.
* MushroomSamba: A literal one, when Ferber feeds an unknowing Chas a salad made with hallucinogenic mushrooms.
* NoCelebritiesWereHarmed: Harry Flowers is a hybrid of the two sets of brothers who notoriously ruled and fought over London's organised crime of the era, South London's Richardsons (the involvement with fraud and the ColdBloodedTorture), and East London's Krays (the homoeroticism and intra-gang violence).
* ThePreciousPreciousCar: Chas pours acid over a lawyer's Rolls-Royce. With the chauffeur [[{{Squick}} handcuffed]] to [[ColdBloodedTorture it]].
* PrettyLittleHeadshots: When [[spoiler:Chas kills Turner]].
* PsychoForHire: Chas, initially.
* RedOniBlueOni: Ferber is Blue, Lucy Red.
* RevealShot: Chas rings the friend who's been trying to get him a passport and asks him to come to Turner's house to deliver it. The shot of the friend widens and we see Flowers' gang are in the room with him.
* SameLanguageDub: The lines delivered by the black musician whose overheard conversation alerts Chas to Turner's free room were overdubbed by Creator/IanMcShane
* SexDrugsAndRockAndRoll: Turner, although he's mostly given up the "rock and roll" part in favor of Sex and Drugs. After meeting Chas, he slowly finds himself returning to music, culminating in "Memo from Turner".
* ShameIfSomethingHappened: At the start of the film, Chas delivers a speech like this to the owner of a minicab firm while [[DepartmentOfRedundancyDepartment actually trashing the place]].
* SharpDressedMan: Chas, until Turner persuades him to go from Mod to Hippie. Meanwhile, Turner abruptly shifts from Hippie to Mod in "Memo from Turner" where he dresses super-sharp and slick.
* ShoutOut:
** Turner's TitleDrop is a quotation from Antonin Artaud.
** Turner reads aloud from the works of Creator/JorgeLuisBorges, and a portrait of him is seen being pierced [[spoiler:by the bullet when Chas shoots Turner]].
* TitleDrop:
-->'''Turner:''' The only performance that makes it, that makes it all the way, is the one that achieves madness.
* TraumaticHaircut: Chas and some of the other gangsters forcibly shave the head of the chauffeur of a lawyer they want to intimidate (and pour acid over his car).
* TwoPersonPoolParty: More than two people actually: there's lots of fun in Turner's big bathtub.
* WhiteDwarfStarlet: Turner
* WritersBlock: Implied to be at the root of Turner's problems.
