''Peeping Tom'' is a 1960 British film by the legendary director Creator/MichaelPowell. The movie can be considered, along with ''Film/{{Psycho}}'', as a precursor of the [[SlasherMovie slasher genre]]. It also triggered a little controversy.

Mark Lewis is a deeply disturbed young man with a movie camera. He works with a film crew and is a filmmaker aspirant, and has a second job as a photographer of erotica. This all serves to feed his obsession with voyeurism and death, which he feeds by making his own private snuff films, killing women and filming their deaths. He also owns a boarding house, and one day he engages in conversation with the family downstairs, and befriends their daughter Helen, eventually forming a relationship with her. He shares some of his home movies with her, along with his childhood problems created by his father. Turns out he used his son as an experiment in psychological fears [[AbusiveParents putting him in stressful situations and filming everything with his camera]].

No one suspects clean-cut, mild-mannered Mark when a prostitute is found dead in his neighborhood, nor do they suspect him when a second victim is found dead on the set of the film he's working on. Finally a chance comment from a psychiatrist leads the police to suspect Mark. Unable to escape his urges, Mark murders his third victim in circumstances that make it obvious he's the killer. He flees back to his boarding house, only to find that Helen has looked at his films and knows the truth about him. She begs him to turn himself in, but instead [[DrivenToSuicide he commits suicide]], giving his documentary an appropriate ending.

The film was highly controversial. Before it was released, it was heavily edited by British censors, with much of the nudity and violence cut out. It was viciously panned by critics and was a flop with audiences, and it wrecked Powell's career. Eventually it was VindicatedByHistory and now is esteemed as an early classic of the horror genre.

A personal favorite of Creator/MartinScorsese. It's also one of the Greatest Films of Creator/RogerEbert.

!!'''This movie contains examples of:'''
* AbusiveParents: His father is the main reason Mark is the way he is.
* AloneWithThePsycho: The climax has Helen trapped with Mark in his film studio room after finding out that he's the killer.
* {{Bowdlerise}}: When it was first released, the censors cut shots of the murders, nudity and Mark’s suicide. Note especially how abruptly the third murder scene, with Mark and a nude Milly, ends.
* {{Camera Fiend}}: Mark is incapable of venturing out without his camera. He films all of his murders, films the police tailing him, and finally films his own suicide.
* CreatorCameo: Director Powell plays Mark's father.
* CruelAndUnusualDeath: To die watching the reflection of your horrified face seems to be horrible.
* DramaticIrony: Mark is about to be interviewed by the police and is filming their investigation.
--> '''Clapper Boy''': Suppose they catch you?\\
'''Mark''': Oh they will. They look very efficient.\\
'''Clapper Boy''': Don't you mind?\\
'''Mark''': No.\\
'''Clapper Boy''': Mark, are you crazy?\\
'''Mark''': [laughs] Yes. Do you think they'll notice?
* DisposableSexWorker: Mark targets prostitutes for his work.
* DrivenToSuicide: To avoid the police.
* EyeOpen: The first shot is an extreme closeup of the eye of Dora the prostitute.
* {{Fanservice}}: The nudity in this film, tame for modern standards, shocked the censors in 1960. Glamour model Pamela Green's nude scene was one of the first in British cinema.
* ForScience: It seems to be his father's motto.
* FreudianExcuse: Mark is turned into a killer by his father's experiments.
* ImprobableWeaponUser: Who could have thought of using a tripod's leg as a butcher’s knife?
* InTheBlood: Mark takes after his father.
* IntroOnlyPointOfView: The whole opening scene is shown from the perspective of Mark's camera.
* MadScientist: Mark's father, who psychologically tortured him in order to study fear.
* MatchCut: From a model pouring a cup of coffee to a guest pouring a drink at Helen's party.
* MurderDotCom: Can be seen as a precursor of sorts.
* ThePeepingTom: Surprised? Mark has a habit of watching people and staring into windows, even when he's not using his camera.
* POVCam: Used for the murder scenes, and justified as they are from Mark's camera.
* PsychologicalHorror: The film is about Paul and his madness.
* SerialKiller: Mark films his victims as he murders them.
* ShoutOut: Mark's stepmother (shown briefly only in home movies) is styled and dressed identically to Kim Novak's "Madeleine" from ''Film/{{Vertigo}}''. Director Powell started out working for [[Creator/AlfredHitchcock Hitchcock]].
* SlasherMovie: Possibly a TropeMaker.
* SlashersPreferBlondes: Mark's first and third victims are a blonde prostitute and a blonde model who's posing nude for him.
* SnuffFilm: Mark's documentary of the girls he's killed.
* {{Streetwalker}}: One has the misfortune of running into Mark.
* [[StuffedIntoTheFridge Stuffed Into The Coffin]]: Only because Mark needed to dispose of the body quick.
* SympatheticMurderer: Mark, arguably one of the first examples. The movie came out in the same year as ''Film/{{Psycho}}'' but differed in that we knew the murderer and spent the whole film from his perspective from the first shot, whereas Hitchcock's film took a baroque approach in making the audience feel a connection for Norman.
* TakeThat: The character of the director is supposed to be a parody of mogul John Davis (the director's name is Don Jarvis, making it not too subtle).
* ThereAreNoTherapists: Averted; there is a psychiatrist, but he's more helpful to the police than to Mark--his casual comment that Mark wanted to know about Mark's father's research on voyeurism cause the police to zero in on Mark as a suspect. He helpfully tells Mark that voyeurism can be cured "quickly" with three years of therapy three times per week.
* TrailersAlwaysSpoil: And so do posters. As you can see in the poster above, it indirectly reveals the secret weapon of Mark.
* TroubledProduction: In-universe. The film that Mark is a crewmember on was having problems with its diva lead actress. The problems get worse when the corpse of Viv the stand-in is discovered in a trunk.
* UrExample: Of the slasher flick.
* WoobieDestroyerOfWorlds: Mark, considering his ''massive'' FreudianExcuse.
* YouBastard: You're watching a film about murderous voyeurism-- to get a thrill out of the story that unfolds.
