-> ''"My God! Iíve just seen Michelangelo Antonioniís ''Blowup''. These Italian directors are a century ahead of me in terms of technique. What have I been doing all this time?"''
-->-- '''Creator/AlfredHitchcock'''

''Blowup'' is a 1966 British-Italian film directed by Creator/MichelangeloAntonioni, his first English-language film. Inspired by the 1959 short story, ''Las babas del diablo'', ("The devil's drool/drivel") by [[Creator/JulioCortazar Julio Cortázar]], and by Swinging UsefulNotes/{{London}} photographer David Bailey.

The plot follows Thomas (David Hemmings), a fashion photographer. One day following a shot he walks through a park taking pictures of people; one person tracks him back to his studio demanding the film which he gives them. He later discovers what seems to be mysterious figure in a negative and the film follows his experiences in searching for answers to these mysteries.

Blowup won a Palme D'Or on the 1967 Cannes Film Festival. A box office and critical smash hit with really explicit sexual content for its time, this film was released in direct defiance to UsefulNotes/TheHaysCode by Creator/{{MGM}} creating a subsidiary label to do it. As a result, the Code was all but done for after that and soon replaced by the present rating system. In short, this film did for its time for cinematic artistic freedom in the 1960s what ''Film/{{Showgirls}}'' utterly failed to do in the 1990s.

Perhaps the archetypal "swinging '60s" movie, at least in Britain. This film inspired the swinging London look of the Film/AustinPowers films, with the character of Thomas being an obvious inspiration for Austin's fashion photographer cover identity.

Blowup was in immediate influence for ''Film/TheConversation'' where a painfully methodic sound engineer tries to discover the second sense in the titular conversation he eavesdropped. Also ''Film/BlowOut'' was modeled after Blowup as it is evident from its title.

!!Tropes associated with this work:

* TheSixties: Specifically, the mid-decade Swinging London/Mod scene. The music, the clothes, the dancing, the apartment, everything.
* BookEnds: The movie starts and ends with a carload of weird mimes tooling around in an old army surplus jeep, yelling at people.
* BlatantLies: After a phone call from a woman Thomas tells Janes that the woman is his wife then denies that she is his wife but admits that they have kids. He immediately says that they do not have kids but adds that she is easy to get on with. Then he recognizes that she is not, that's why they do not live together.
* TheCameo: The most obvious are Music/TheYardbirds (with both Jimmy Page and Jeff Beck), who play at a local club. In the same scene you can also spot Creator/MichaelPalin between the crowd.
* CameraFiend: Thomas.
* CatFight: The two girls that come to Thomas's apartment have a giggling {{Fanservice}}-y faux Cat Fight in which the one girl, who is already topless, renders the second girl topless. Then Thomas joins in and more clothing gets removed and three-way sex follows.
* CoitusUninterruptus: At one point Thomas, who's looking for answers about the dead guy, goes to Jane's apartment and finds her in bed, a man humping away on top of her. The man doesn't notice him but Jane does, and she motions for him to leave. After lingering for a bit he does.
* CoolCar
* {{Doppelganger}}: Sitting in a cafe with his friend Thomas sees a young man who closely resembles him from the back. He exits and sees the man once more from the front and he still looks like the protagonist. He doesn't follow the doppelgänger who gets in the car down the street then the camera cuts off.
* DoesThisRemindYouOfAnything: Thomas' shooting session with Veruschka (pictured above) is highly reminiscent of sexual intercourse.
* EnhanceButton: [[AvertedTrope Averted]]. He tries to enlarge (blowup) the picture, but it loses resolution with each try. The fact is [[LampshadeHanging lampshaded]] by Bill's girlfriend.
* EveryoneHatesMimes: Decisively averted. Mimes are mysterious but ultimately benevolent.
* ExtremelyShortTimespan: It spans over less than 24 hours.
* {{Foreshadowing}}: When discussing a book he is making with his photographs, Thomas says something along the lines of "It's violent, I want to end it with something peaceful". The last scenes of the movie are as peaceful as you can get.
* GainaxEnding: The film starts to get downright weird at the end. Thomas comes back to his apartment to find all of the incriminating photos having disappeared, except for one blurry image of the body that fell behind some furniture. He spots Jane outside a club, only for her to literally disappear into thin air. Finally, the last scene has Thomas re-visiting the park to find that the corpse has disappeared as well. The carload of weird mimes shows up again, as they scamper into the park and onto a tennis court, where two of them mime playing tennis without a ball. Despite the lack of a ball we start hearing the sound of a ball being hit around on the court. Then we see Thomas walking away as the camera pulls back into a crane shot...only for Thomas to disappear into thin air as well, as TheEnd comes onscreen.
* {{Gaydar}}: Thomas unequivocally identifies a pair of young men with poodles as gay.
* HandOrObjectUnderwear: Jane takes off her blouse and subsequently always uses a hand to cover her breast when she is shown frontally. When the angle doesn't allow the viewer to see her breasts she doesn't. Her breasts are never seen.
** In one shot the hand of Thomas closes the view of Jane's breasts.
* HotterAndSexier: As compared to both the prevous films of Antonioni and the cinema of the early 60's in general.
* InspiredBy: A short story by Creator/JulioCortazar
* {{Jerkass}}: Thomas.
* KingIncognito: Thomas spending night in the asylum for the homeless disguised as the one of them.
* MayDecemberRomance: Jane and her park date. Lampshaded by Thomas.
* MocksteryTale: Thomas accidentally uncovers a murder. He attempts to investigate it, but he doesn't seem very enthusiastic in spite of actually finding the victim's body, his investigation ends in vain and the ending implies that he doesn't or shouldn't really care.
* NeverFoundTheBody: Zigzagged. [[spoiler: First Thomas returns to the park and finds the body on the spot where it was seen on his photo. The corpse is clearly there. Thomas leaves the place. When he returns again it is gone for good.]]
* NoCelebritiesWereHarmed Thomas is made basing on David Bailey, John Cowan and Terence Donovan, contemporary photographing celebrities.
* OnlyOneName: For everyone in the movie.
* {{Paparazzi}}: Thomas acts as such in the crucial scene where he secretly makes shots in the park then photographs Janes
* RewindReplayRepeat: An UnbuiltTrope version, as Thomas winds up obsessively blowing up and studying a detail from a single photograph.
* RockersSmashGuitars: After using it to perform PercussiveMaintenance on a misbehaving amp.
* SceneryCensor: When Jane takes her top off and basically dares Thomas to photograph her, she's strategically hidden behind some stage feathers. When Thomas takes her by the arm and tells her to get dressed, his arms provide the scenery censorship.
* SexyDiscretionShot: The film certainly showed more nudity than any other mainstream film to run in the United States or Britain prior to that time, but the boundary pushing only went so far. After most of the clothes in the ThreeWaySex scene have been removed we cut to the aftermath, with the two girls again fully clothed and gently putting Thomas's shoes back on.
* ShesGotLegs: Jane, as played by a 29-year-old Vanessa Redgrave, certainly has them.
* {{Sideboob}}: Veruschka in the early photography session has a dress that features this.
* SpiritualSuccessor: Antonioni's next film ''Film/ZabriskiePoint'' dealt with America's counter-culture, featuring PopStarComposer Music/PinkFloyd, ambiguous GainaxEnding, and a much darker tone.
* SpookyPhotographs: The Blow-Ups of the photograph keep making the original look blurrier and scarier and harder to understand.
* ThreeWaySex: Between Thomas and the two girls who show up to his apartment uninvited.
* ToplessnessFromTheBack: At one point Vanessa Redgrave is shown like that.
* TrueArtIsIncomprehensible: InUniverse, Bill's paintings.
--> '''Bill:''' They don't mean anything when I do them - just a mess. Afterwards I find something to hang onto -like that- like- like... that leg. ''(points at a random line)'' [[{{Foreshadowing}} And then it sorts itself out. It adds up. It's like finding a clue in a detective story]].
* TwoActStructure: The first half of the movie is a rather episodic study of the life of a young fashion photographer in London--lots of scantily clad models, hipster friends, parties, a vague sense of ennui. Then halfway through Thomas notices what appears to be a murder in the background of his picture of Jane, and the film becomes something different, as he tries, somewhat halfheartedly, to solve the mystery.
* UnbuiltTrope: The EnhanceButton (or at least an analog version of it).
* TheUnreveal: Just what the hell was the deal with the dead guy in the park, hm? Did Jane conspire to commit murder, or not?
* VehicleVanish: Done with people instead of a vehicle, and in a distinctly surreal manner. Thomas is driving downtown when he spots Jane across the street outside a nightclub. As he's parking the car, a group of people pass in front of Jane...and she disappears. She isn't there when the people pass, and she's never seen in the movie again.
* WavingSignsAround: A tiny anti-military rally where participants carry antiwar signs crosses the street when Thomas stops at the trafic lights. Unexplicably one girl puts her sign in his expensive car and he accepts it. [[spoiler: he soon gets rid of it]]
