A Clockwork Orange (film)



A Clockwork Orange is a 1971 dystopian crime film adapted, produced, and directed by Stanley Kubrick, based on Anthony Burgess's novel A Clockwork Orange. It employs disturbing, violent images to comment on psychiatry, juvenile delinquency, youth gangs, and other social, political, and economic subjects in a dystopian near-future Britain.

Alex (Malcolm McDowell), the central character, is a charismatic, antisocial delinquent whose interests include classical music (including Beethoven), committing rape, and what is termed "ultra-violence". He leads a small gang of thugs, Pete (Michael Tarn), Georgie (James Marcus), and Dim (Warren Clarke), whom he calls his droogs (from the Russian word друг, "friend", "buddy"). The film chronicles the horrific crime spree of his gang, his capture, and attempted rehabilitation via an experimental psychological conditioning technique (the "Ludovico Technique") promoted by the Minister of the Interior (Anthony Sharp). Alex narrates most of the film in Nadsat, a fractured adolescent slang composed of Slavic (especially Russian), English, and Cockney rhyming slang.

The soundtrack to A Clockwork Orange features mostly classical music selections and Moog synthesizer compositions by Wendy Carlos. The artwork for the poster of A Clockwork Orange was created by Philip Castle with the layout by designer Bill Gold.

Plot
In a futuristic Britain, Alex DeLarge is the leader of a gang of "droogs", Georgie, Dim and Pete. One night, after getting intoxicated on drug-laden "milk-plus", they engage in an evening of "ultra-violence", which includes a fight with a rival gang led by Billyboy. They drive to the country home of writer F. Alexander and beat him to the point of crippling him for life. Alex then rapes Alexander's wife while singing "Singin' in the Rain". The next day, while truant from school, Alex is approached by his probation officer Mr P.R. Deltoid, who is aware of Alex's activities and cautions him.

Alex's droogs express discontent with petty crime and want more equality and high yield thefts, but Alex asserts his authority by attacking them. Later, Alex invades the home of a wealthy "cat-lady" and bludgeons her with a phallic sculpture while his droogs remain outside. On hearing sirens, Alex tries to flee but Dim smashes a bottle in his face, stunning him and leaving him to be arrested by the police. With Alex in custody, Mr Deltoid gloats that the woman he attacked died, making Alex a murderer. He is sentenced to fourteen years in prison.

Two years into the sentence, Alex eagerly takes up an offer to be a test subject for the Minister of the Interior's new Ludovico technique, an experimental aversion therapy for rehabilitating criminals within two weeks. Alex is strapped to a chair, his eyes are clamped open and he is injected with drugs. He is then forced to watch films of sex and violence, some of which are accompanied by the music of his favourite composer, Ludwig van Beethoven. Alex becomes nauseated by the films and, fearing the technique will make him sick upon hearing Beethoven, begs for an end to the treatment.

Two weeks later, the Minister demonstrates Alex's rehabilitation to a gathering of officials. Alex is unable to fight back against an actor who taunts and attacks him and becomes ill wanting sex with a topless woman. The prison chaplain complains that Alex has been robbed of his free will; the Minister asserts that the Ludovico technique will cut crime and alleviate crowding in prisons.

Alex is let out as a free man, only to find that the police have sold his possessions as compensation to his victims and his parents have let out his room. Alex encounters an elderly vagrant whom he had attacked years earlier, and the vagrant and his friends attack him. Alex is saved by two policemen but is shocked to find they are his former droogs Dim and Georgie. They drive him to the countryside, beat him up, and nearly drown him before abandoning him. Alex barely makes it to the doorstep of a nearby home before collapsing.

Alex wakes up to find himself in the home of Mr Alexander, where he is being cared for by Alexander's manservant, Julian. Mr Alexander does not recognise Alex from the previous attack but knows of Alex and the Ludovico technique from the newspapers. He sees Alex as a political weapon and prepares to present him to his colleagues. While bathing, Alex breaks into "Singin' in the Rain", causing Mr Alexander to realise that Alex was the person who assaulted him and his wife. With help from his colleagues, Mr Alexander drugs Alex and locks him in an upstairs bedroom. He then plays Beethoven's Ninth Symphony loudly from the floor below. Alex is unable to withstand the sickening pain and attempts suicide by throwing himself out the window, falling unconscious on the ground.

Alex wakes up in a hospital with broken bones. While being given a series of psychological tests, Alex finds that he no longer has aversions to violence and sex. The Minister arrives and apologises to Alex. He offers to take care of Alex and get him a job in return for his cooperation with his election campaign and public relations counter-offensive. As a sign of goodwill, the Minister brings in a stereo system playing Beethoven's Ninth. Alex then contemplates violence and has vivid thoughts of having sex with a woman in front of an approving crowd, and thinks to himself, "I was cured, all right!"

Morality
The film's central moral question (as in many of Burgess's novels) is the definition of "goodness" and whether it makes sense to use aversion therapy to stop immoral behaviour. Stanley Kubrick, writing in Saturday Review, described the film as:A social satire dealing with the question of whether behavioural psychology and psychological conditioning are dangerous new weapons for a totalitarian government to use to impose vast controls on its citizens and turn them into little more than robots." Similarly, on the film production's call sheet (cited at greater length above), Kubrick wrote:"It is a story of the dubious redemption of a teenage delinquent by condition-reflex therapy. It is, at the same time, a running lecture on free-will. After aversion therapy, Alex behaves like a good member of society, though not through choice. His goodness is involuntary; he has become the titular clockwork orange — organic on the outside, mechanical on the inside. After Alex has undergone the Ludovico technique, the chaplain criticises his new attitude as false, arguing that true goodness must come from within. This leads to the theme of abusing liberties — personal, governmental, civil — by Alex, with two conflicting political forces, the Government and the Dissidents, both manipulating Alex purely for their own political ends. The story portrays the "conservative" and "liberal" parties as equally worthy of criticism: the writer Frank Alexander, a victim of Alex and his gang, wants revenge against Alex and sees him as a means of definitively turning the populace against the incumbent government and its new regime. Mr Alexander fears the new government; in a telephone conversation, he says: Recruiting brutal young roughs into the police; proposing debilitating and will-sapping techniques of conditioning. Oh, we've seen it all before in other countries; the thin end of the wedge! Before we know where we are, we shall have the full apparatus of totalitarianism.

On the other side, the Minister of the Interior (the Government) jails Mr Alexander (the Dissident Intellectual) on the excuse of his endangering Alex (the People), rather than the government's totalitarian regime (described by Mr Alexander). It is unclear whether or not he has been harmed; however, the Minister tells Alex that the writer has been denied the ability to write and produce "subversive" material that is critical of the incumbent government and meant to provoke political unrest.

Psychology
Another target of criticism is the behaviourism or "behavioural psychology" propounded by psychologists John B. Watson and B. F. Skinner. Burgess disapproved of behaviourism, calling Skinner's book Beyond Freedom and Dignity (1971) "one of the most dangerous books ever written". Although behaviourism's limitations were conceded by its principal founder, Watson, Skinner argued that behaviour modification — specifically, operant conditioning (learned behaviours via systematic reward-and-punishment techniques) rather than the "classical" Watsonian conditioning — is the key to an ideal society. The film's Ludovico technique is widely perceived as a parody of aversion therapy, which is a form of classical conditioning.

Author Paul Duncan said of Alex: "Alex is the narrator so we see everything from his point of view, including his mental images. The implication is that all of the images, both real and imagined, are part of Alex's fantasies". Psychiatrist Aaron Stern, the former head of the MPAA rating board, believed that Alex represents man in his natural state, the unconscious mind. Alex becomes "civilised" after receiving his Ludovico "cure" and the sickness in the aftermath Stern considered to be the "neurosis imposed by society". Kubrick told film critics Philip Strick and Penelope Houston that he believed Alex "makes no attempt to deceive himself or the audience as to his total corruption or wickedness. He is the very personification of evil. On the other hand, he has winning qualities: his total candour, his wit, his intelligence and his energy; these are attractive qualities and ones, which I might add, which he shares with Richard III".

Production
McDowell was chosen for the role of Alex after Kubrick saw him in the film if.... (1968). He also helped Kubrick on the uniform of Alex's gang, when he showed Kubrick the cricket whites he had. Kubrick asked him to put the box (jockstrap) not under but on top of the costume.

During the filming of the Ludovico technique scene, McDowell scratched a cornea, and was temporarily blinded. The doctor standing next to him in the scene, dropping saline solution into Alex's forced-open eyes, was a real physician present to prevent the actor's eyes from drying. McDowell also cracked some ribs filming the humiliation stage show. A unique special effect technique was used when Alex jumps out of the window in an attempt to commit suicide and the viewer sees the ground approaching the camera until collision, i.e., as if from Alex's point of view. This effect was achieved by dropping a Newman Sinclair clockwork camera in a box, lens-first, from the third storey of the Corus Hotel. To Kubrick's surprise, the camera survived six takes.

On the 24th of February 1971, the last day of shooting, Progress Report No. 113 has a summary of all the footage shot to date: 39,880 feet wasted, 377,090 feet exposed, 13,120 feet remain as short ends with a total of 452,960 feet used. Sound: 225,880 feet printed from 288 1/4" reel to reel tapes.

Adaptation
The cinematic adaptation of A Clockwork Orange (1962) was not initially planned. Screenplay writer Terry Southern gave Kubrick a copy of the novel, but, as he was developing a Napoleon Bonaparte–related project, Kubrick put it aside. Kubrick's wife, in an interview, stated she then gave him the novel after having read it. It had an immediate impact. Of his enthusiasm for it, Kubrick said, "I was excited by everything about it: the plot, the ideas, the characters, and, of course, the language. The story functions, of course, on several levels: political, sociological, philosophical, and, what's most important, on a dreamlike psychological-symbolic level." Kubrick wrote a screenplay faithful to the novel, saying, "I think whatever Burgess had to say about the story was said in the book, but I did invent a few useful narrative ideas and reshape some of the scenes." Kubrick based the script on the shortened US edition of the book, which omitted the final chapter.

Novelist's response
Burgess had mixed feelings about the film adaptation of his novel, publicly saying he loved Malcolm McDowell and Michael Bates, and the use of music; he praised it as "brilliant", even so brilliant that it might be dangerous. Despite this enthusiasm, he was concerned that it lacked the novel's redemptive final chapter, an absence he blamed upon his American publisher and not Kubrick. All US editions of the novel prior to 1986 omitted the final chapter.

Burgess reports in his autobiography You've Had Your Time (1990) that he and Kubrick at first enjoyed a good relationship, each holding similar philosophical and political views and each very interested in literature, cinema, music, and Napoleon Bonaparte. Burgess's novel Napoleon Symphony (1974) was dedicated to Kubrick. Their relationship soured when Kubrick left Burgess to defend the film from accusations of glorifying violence. A lapsed Catholic, Burgess tried many times to explain the Christian moral points of the story to outraged Christian organisations and to defend it against newspaper accusations that it supported fascist dogma. He also went to receive awards given to Kubrick on his behalf. Despite the benefits Burgess made from the film, he was in no way involved in the production of the book's adaptation. The only profit he made directly from the film was the initial $500 that was given to him for the rights to the adaptation.

Direction
Kubrick was a perfectionist who researched meticulously, with thousands of photographs taken of potential locations, as well as many scene takes; however, per Malcolm McDowell, he usually "got it right" early on, so there were few takes. So meticulous was Kubrick that McDowell stated "If Kubrick hadn't been a film director he'd have been a General Chief of Staff of the US Forces. No matter what it is—even if it's a question of buying a shampoo it goes through him. He just likes total control." Filming took place between September 1970 and April 1971, making A Clockwork Orange the quickest film shoot in his career. Technically, to achieve and convey the fantastic, dream-like quality of the story, he filmed with extreme wide-angle lenses such as the Kinoptik Tegea 9.8mm for 35mm Arriflex cameras, and used fast- and slow motion to convey the mechanical nature of its bedroom sex scene or stylise the violence in a manner similar to Toshio Matsumoto's Funeral Parade of Roses (1969).

Nature of the society
The society depicted in the film was perceived by some as Communist (as Michel Ciment pointed out in an interview with Kubrick) due to its slight ties to Russian culture. The teenage slang has a heavily Russian influence, as in the novel; Burgess explains the slang as being, in part, intended to draw a reader into the world of the book's characters and to prevent the book from becoming outdated. There is some evidence to suggest that the society is a socialist one, or perhaps a society evolving from a failed socialism into a fully fascist society. In the novel, streets have paintings of working men in the style of Russian socialist art, and in the film, there is a mural of socialist artwork with obscenities drawn on it. As Malcolm McDowell points out on the DVD commentary, Alex's residence was shot on failed municipal architecture, and the name "Municipal Flat Block 18A, Linear North" alludes to socialist-style housing.

Later in the film, when the new right-wing government takes power, the atmosphere is certainly more authoritarian than the anarchist air of the beginning. Kubrick's response to Ciment's question remained ambiguous as to exactly what kind of society it is. Kubrick asserted that the film held comparisons between both the left and right end of the political spectrum and that there is little difference between the two. Kubrick stated, "The Minister, played by Anthony Sharp, is clearly a figure of the Right. The writer, Patrick Magee, is a lunatic of the Left... They differ only in their dogma. Their means and ends are hardly distinguishable."

Locations
A Clockwork Orange was photographed mostly on location in metropolitan London and within quick access of Kubrick's then home in Barnet Lane, Elstree.

Shooting began on 7 September 1970 with call sheet no. 1 at the Duke Of New York pub: an unused scene and the first of many unused locations. A few days later, shooting commenced in Alex's Ludovico treatment bedroom and the Serum 114 injection by Dr Branom.

New Year's Eve started with rehearsals at the Korova Milk Bar and shooting finished after four continuous days on 8 January.

The last scenes were shot in February 1971, ending with call sheet no. 113. The last main scene to be filmed was Alex's fight with Billy Boy's gang, which took six days to cover. Shooting encompassed a total of around 113 days over six months of fairly continuous shooting. As is normal practice, there was no attempt to shoot the script in chronological order.

The few scenes not shot on location were the Korova Milk Bar, the prison check-in area, Alex having a bath at F. Alexander's house, and two corresponding scenes in the hallway. These sets were built at an old factory on Bullhead Road, Borehamwood, which also served as the production office. Seven call sheets are missing from the Stanley Kubrick Archive, so some locations, such as the hallway, cannot be confirmed.

Otherwise, locations used in the film include:
 * The attack on the tramp was filmed at the (since renovated) pedestrian underpass under York Road Roundabout at the southern end of Wandsworth Bridge, Wandsworth, London.
 * The unused scene of the attack on the professor was shot in Friars Square shopping centre in Aylesbury, Buckinghamshire, (then open, since covered) but dropped due to the actor dying. For the subsequent scene where the professor recognises Alex towards the latter part of the film, the tramp plays the character who recognises Alex.
 * The Billyboy gang fight occurs at the then-derelict Karsino hotel on Tagg's Island, Kingston upon Thames, demolished soon after.
 * Alex's apartment is on the top floor of Canterbury House tower block, Borehamwood, Hertfordshire. An exterior blue plaque and mosaic at ground level commemorate the film's location.The Chelsea Drugstore.jpg
 * The record shop where Alex picks up the two young women was in the basement of the former Chelsea Drugstore, located on the corner of Royal Avenue and King's Road in Chelsea.
 * The 'Menacing Car scene' where the Durango '95 forces the VW Beetle, motorcycle and Transit van off the road, were shot on Rectory Lane just south of Shenley Lodge. Driving under the lorry trailer was shot by Colney Heath on Bullens Green Lane at the crossroads of Fellowes Lane, Hertfordshire.
 * The home of the writer, site of the rape and beating, was filmed at three different locations: the arrival in the "Durango 95" by the "HOME" sign was shot on the lane leading to Munden House, which is off School Lane, Bricket Wood, the house's exterior and garden with the footbridge over the pond is Milton Grundy's Japanese garden in Shipton-under-Wychwood, Oxfordshire and the interior is Skybreak House in The Warren, Radlett, Hertfordshire.
 * Alex throws Dim and Georgie into South Mere lake at Thamesmead South Housing Estate, London (the background block is now demolished). This is 200 yards north of where Alex walks home at night through an elevated plaza surrounded by buildings (since demolished), whistling and kicking rubbish.
 * The "Duke Of New York" pub is the since-demolished "The Bottle and Dragon" pub (formerly "The Old Leather Bottle") in Stonegrove, Edgware, London.
 * The Cat Lady house where Alex is caught by police is Shenley Lodge, Rectory Lane, Shenley, Hertfordshire.
 * The prison's exterior is HMP Wandsworth, its interior is the Woolwich Barracks' since-demolished prison wing, Woolwich, London.
 * The chapel in which Alex scrolls the lyrics as the prisoners sing is a since-demolished lecture room at St. Edward's College, Totteridge Lane, North London. The library where he reads, fantasizes and then discusses the Ludovico Treatment with the priest was underneath the lecture room. The prison governor's office, where Alex signs consent for the Ludovico treatment, is on the same site (still standing).
 * The two biblical fantasy scenes (Christ and the fight scene) were filmed at Dashwood Mausoleum, West Wycombe, Buckinghamshire.
 * The check-in at Ludovico Medical Clinic, the brain-washing film theatre, Alex's apartment block lobby with the broken elevator, Alex's hospital bedroom and police interrogation/beating room (since demolished) are all at Brunel University, Uxbridge, Middlesex.
 * The Minister's presentation to the media of Alex's "cure" takes place at the Nettlefold Hall inside West Norwood Library, West Norwood, London.
 * Alex is attacked by vagrants underneath the north side of the Albert Bridge, Chelsea, London.
 * The scene where Dim and Georgie take Alex down the country lane in the police Land Rover and subsequent water trough beating is School Lane, Bricket Wood, Hertfordshire.
 * Alex's suicide bid leap and corresponding billiard room were at the old Edgwarebury Country Club, Barnet Lane, Elstree, Hertfordshire.
 * The hospital in which Alex recovers is Princess Alexandra Hospital, in Harlow, Essex.
 * The final sexual fantasy was shot at the since-demolished Handley Page Ltd's hangars, Radlett, Hertfordshire.

Music
Despite Alex's obsession with Beethoven, the soundtrack contains more music by Rossini than by Beethoven. The fast-motion sex scene with the two girls, the slow-motion fight between Alex and his Droogs, the fight with Billy Boy's gang, the drive to the writer's home ("playing 'hogs of the road'"), the invasion of the Cat Lady's home, and the scene where Alex looks into the river and contemplates suicide before being approached by the beggar are all accompanied by Rossini's music.

Critical reception
A Clockwork Orange was a box-office success in the United States. It grossed more than $26 million on a conservative budget of $2.2 million, was critically acclaimed, and was nominated for several awards, including the Academy Award for Best Picture (losing to The French Connection). , A Clockwork Orange holds a 90% "Certified Fresh" rating among critics on Rotten Tomatoes, based on 60 reviews with an average rating of 8.41/10. The website's critical consensus states: "Disturbing and thought-provoking, A Clockwork Orange is a cold, dystopian nightmare with a very dark sense of humor".

The movie was the most popular film of 1972 in France with 7,611,745 admissions.

Vincent Canby of The New York Times praised the film saying: McDowell is splendid as tomorrow's child, but it is always Mr. Kubrick's picture, which is even technically more interesting than 2001. Among other devices, Mr. Kubrick constantly uses what I assume to be a wide-angle lens to distort space relationships within scenes, so that the disconnection between lives, and between people and environment, becomes an actual, literal fact. The following year, after the film won the New York Film Critics Award, he called it "a brilliant and dangerous work, but it is dangerous in a way that brilliant things sometimes are".

Despite praise from many critics, the film had detractors. Film critic Stanley Kauffmann commented, "Inexplicably, the script leaves out Burgess' reference to the title". Roger Ebert gave A Clockwork Orange two stars out of four, calling it an "ideological mess". In her New Yorker review titled "Stanley Strangelove", Pauline Kael called it pornographic because of how it dehumanised Alex's victims while highlighting the sufferings of the protagonist. Kael derided Kubrick as a "bad pornographer", noting the Billyboy's gang extended stripping of the very buxom woman they intended to rape, claiming it was offered for titillation.

John Simon noted that the novel's most ambitious effects were based on language and the alienating effect of the narrator's Nadsat slang, making it a poor choice for a film. Concurring with some of Kael's criticisms about the depiction of Alex's victims, Simon noted that the writer character (young and likeable in the novel) was played by Patrick Magee, "a very quirky and middle-aged actor who specialises in being repellent". Simon comments further that "Kubrick over-directs the basically excessive Magee until his eyes erupt like missiles from their silos and his face turns every shade of a Technicolor sunset".

The film was re-released in North America in 1973 and earned $1.5 million in rentals.

American version
In the United States, A Clockwork Orange was rated X in its original release in 1972. Later, Kubrick voluntarily replaced approximately 30 seconds of sexually explicit footage from two scenes with less explicit action for an R rating re-release in 1973. Current DVDs present the original version (reclassified with an "R" rating), and only some of the early 1980s VHS editions are the edited version.

Because of the explicit sex and violence, The National Catholic Office for Motion Pictures rated it C ("Condemned"), a rating which forbade Roman Catholics seeing the film. In 1982, the Office abolished the "Condemned" rating. Subsequently, films deemed to have unacceptable levels of sex and violence by the Conference of Bishops are rated O, "Morally Offensive".

British withdrawal
Although it was passed uncut for UK cinemas in December 1971, British authorities considered the sexual violence in the film to be extreme. In March 1972, during the trial of a 14-year-old male accused of the manslaughter of a classmate, the prosecutor referred to A Clockwork Orange, suggesting that the film had a macabre relevance to the case. The film was also linked to the murder of an elderly vagrant by a 16-year-old boy in Bletchley, Buckinghamshire, who pleaded guilty after telling police that friends had told him of the film "and the beating up of an old boy like this one". Roger Gray QC, for the defence, told the court that "the link between this crime and sensational literature, particularly A Clockwork Orange, is established beyond reasonable doubt". The press also blamed the film for a rape in which the attackers sang "Singin' in the Rain" as "Singin' in the Rape". Christiane Kubrick, the director's wife, has said that the family received threats and had protesters outside their home.

The film was withdrawn from British release in 1973 by Warner Brothers at the request of Kubrick. In response to allegations that the film was responsible for copycat violence Kubrick stated: "To try and fasten any responsibility on art as the cause of life seems to me to put the case the wrong way around. Art consists of reshaping life, but it does not create life, nor cause life. Furthermore, to attribute powerful suggestive qualities to a film is at odds with the scientifically accepted view that, even after deep hypnosis in a posthypnotic state, people cannot be made to do things which are at odds with their natures."

The Scala Cinema Club went into receivership in 1993 after losing a legal battle following an unauthorised screening of the film. In the same year, Channel 4 broadcast Forbidden Fruit, a 27-minute documentary about the withdrawal of the film in Britain. It contains footage from A Clockwork Orange. It was difficult to see A Clockwork Orange in the United Kingdom for 27 years. It was only after Kubrick died in 1999 that the film was theatrically re-released and made available on VHS and DVD. On 4 July 2001, the uncut version premiered on Sky TV's Sky Box Office, where it ran until mid-September.

Censorship in other countries
In Ireland, the film was banned on 10 April 1973. Warner Bros. decided against appealing the decision. Eventually, the film was passed uncut for cinema on 13 December 1999 and released on 17 March 2000. The re-release poster, a replica of the original British version, was rejected due to the words "ultra-violence" and "rape" in the tagline. Sheamus Smith explained his rejection to the Irish Times: I believe that the use of those words in the context of advertising would be offensive and inappropriate.

In Singapore, the film was banned for over 30 years, before an attempt at release was made in 2006. However, the submission for a M18 rating was rejected, and the ban was not lifted. The ban was later lifted and the film was shown uncut (with an R21 rating) on 28 October 2011, as part of the Perspectives Film Festival.

In South Africa, it was banned under the apartheid regime for 13 years, then in 1984 was released with one cut and only made available to people over the age of 21. It was banned in South Korea and in the Canadian provinces of Alberta and Nova Scotia. Alberta reversed the ban upon Kubrick's death in 1999. The Maritime Film Classification Board also reversed the ban eventually. Both jurisdictions now grant an R rating to the film.

Differences between the film and the novel
Kubrick's film is relatively faithful to the Burgess novel, omitting only the final, positive chapter, in which Alex matures and outgrows sociopathy. While the film ends with Alex being offered an open-ended government job, implying he remains a sociopath at heart, the novel ends with Alex's positive change in character. This plot discrepancy occurred because Kubrick based his screenplay on the novel's American edition, in which the final chapter had been deleted on the insistence of its American publisher. He claimed not to have read the complete, original version of the novel until he had almost finished writing the screenplay, and that he never considered using it. The introduction to the 1996 edition of A Clockwork Orange says that Kubrick found the end of the original edition too blandly optimistic and unrealistic. One example of this would be differences in the portrayal of P. R. Deltoid, Alex's "post-corrective advisor". In the novel, P. R. Deltoid appears to have some moral authority (although not enough to prevent Alex from lying to him or engaging in crime, despite his protests). In the film, Deltoid is slightly sadistic and seems to have a sexual interest in Alex, interviewing him in his parents' bedroom and smacking him in the crotch.
 * In the novel, Alex's last name was never revealed, while in the film, his surname is 'DeLarge', due to Alex's calling himself "Alexander the Large" in the novel.
 * At the beginning of the novel, Alex is a 15-year-old juvenile delinquent. In the film, to lessen the controversy, Alex is portrayed as somewhat older, around 17 or 18.
 * Critic Randy Rasmussen has argued that the government in the film is in a shambolic state of desperation, whereas the government in the novel is quite strong and self-confident. The former reflects Kubrick's preoccupation with the theme of acts of self-interest masked as simply following procedure.
 * In the film, Alex has a pet snake. There is no mention of this in the novel.
 * In the novel, F. Alexander recognises Alex through a number of careless references to the previous attack (e.g., his wife then claiming they did not have a telephone). In the film, Alex is recognised when singing the song 'Singing in the Rain' in the bath, which he had hauntingly done while attacking F. Alexander's wife. The song does not appear at all in the book, as it was an improvisation by actor Malcolm McDowell when Kubrick complained that the rape scene was too "stiff".
 * In the novel, Alex is offered up for treatment after killing a fellow inmate who was sexually harassing him. In the film, this scene was cut out and, instead of Alex practically volunteering for the procedure, he was simply selected by the Interior Minister for speaking up during a ministerial inspection of the prison.
 * Alex's prison number in the novel is 6655321. His prison number in the film is 655321.
 * In the novel, Alex drugs and rapes two 10-year-old girls. In the film, the girls are young adults who seem to have consensual, playful sex with him, with no suggestion of using any drugs and without any violence.
 * In the novel, the writer was working on a manuscript called A Clockwork Orange when Alex and his gang are breaking into his house. In the movie, the title of the manuscript is not visible, leaving no literal reference to the title of the movie. Some explanations of the title are offered in the Analysis section of the novel.
 * Early in the film, Alex and his droogs brutally attack a drunk, homeless man. Later, when Alex is returned to society, he is recognised by the same man. The homeless man gathers several other homeless men to beat Alex, who is unable to defend himself. These scenes do not appear in the book, but there is a similar scene in which an elderly man heading home from the library is beaten and his books destroyed by the droogs. After Alex is returned to society, he decides he wants to kill himself and goes to a library to find a book on how to do it. There, he is recognised by the man he had beaten and is attacked by him and a gang of other old library patrons.
 * Alex is beaten nearly to death by the police after his rehabilitation. In the film, the policemen are two of his former droogs, Dim and Georgie. In the book, instead of Georgie, who was said to have been killed, the second officer is Billyboy, the leader of the opposing gang whom Alex and his droogs fought earlier, both in the film and the book.
 * The film concludes with Alex recovering from his suicide attempt in hospital. In the novel, Alex leaves the hospital and forms a new band of droogs, but is unsatisfied by the violent activities which once entertained him. He encounters Peter (one of his former droogs) in a café, and is fascinated by the seemingly nonviolent life he now leads. The story closes with Alex suggesting that he might try to pursue a similar, peaceful lifestyle.
 * In the novel, Alex is accidentally conditioned against all music, but in the film he is only conditioned against Beethoven's 9th Symphony.

Home media
In 2000, the film was released on VHS and DVD, both individually and as part of The Stanley Kubrick Collection DVD set. Due to negative comments from fans, Warner Bros re-released the film, its image digitally restored and its soundtrack remastered. A limited-edition collector's set with a soundtrack disc, film poster, booklet and film strip followed, but later was discontinued. In 2005, a British re-release, packaged as an "Iconic Film" in a limited-edition slipcase was published, identical to the remastered DVD set, except for different package cover art. In 2006, Warner Bros announced the September publication of a two-disc special edition featuring a Malcolm McDowell commentary, and the releases of other two-disc sets of Stanley Kubrick films. Several British retailers had set the release date as 6 November 2006; the release was delayed and re-announced for 2007 Holiday Season.

An HD DVD, Blu-ray, and DVD re-release version of the film was released on 23 October 2007. The release accompanies four other Kubrick classics. 1080p video transfers and remixed Dolby TrueHD 5.1 (for HD DVD) and uncompressed 5.1 PCM (for Blu-ray) audio tracks are on both the Blu-ray and HD DVD editions. Unlike the previous version, the DVD re-release edition is anamorphically enhanced. The Blu-ray was reissued for the 40th anniversary of the film's release, identical to the previously released Blu-ray, apart from adding a Digibook and the Stanley Kubrick: A Life in Pictures documentary as a bonus feature.

Along with Bonnie and Clyde (1967), Night of the Living Dead (1968), The Wild Bunch (1969), Soldier Blue (1970), Dirty Harry (1971), and Straw Dogs (1971), the film is considered a landmark in the relaxation of control on violence in the cinema.

A Clockwork Orange remains an influential work in cinema and other media. The film is frequently referenced in popular culture, which Adam Chandler of The Atlantic attributes to Kubrick's "genre-less" directing techniques that brought novel innovation in filming, music, and production that had not been seen at the time of the film's original release.

A Clockwork Orange appears several times on the American Film Institute's (AFI) top movie lists. The film was listed at #46 in the 1998 AFI's 100 Years... 100 Movies, at #70 in the 2007 second listing. "Alex DeLarge" is listed 12th in the villains section of the AFI's 100 Years... 100 Heroes and Villains. In 2008, the AFI's 10 Top 10 rated A Clockwork Orange as the 4th greatest science-fiction movie to date. The film was also placed 21st in the AFI's 100 Years... 100 Thrills

In the British Film Institute's 2012 Sight & Sound polls of the world's greatest films, A Clockwork Orange was ranked 75th in the directors' poll and 235th in the critics' poll. In 2010, Time magazine placed it 9th on their list of the Top 10 Ridiculously Violent Movies. In 2008, Empire ranked it 37th on their list of "The 500 Greatest Movies of All Time", and in 2013, Empire ranked it 11th on their list of "The 100 Best British Films Ever". The Spanish director Luis Buñuel praised the film highly. He once said: "A Clockwork Orange is my current favourite. I was predisposed against the film. After seeing it, I realised it is only a movie about what the modern world really means".
