THX 1138

The film's title-card

In the future, sexual intercourse and reproduction are prohibited, whereas use of mind-altering drugs is mandatory to enforce compliance among the citizens and to ensure their ability to conduct dangerous and demanding tasks. Emotions and the concept of family are taboo. Workers are clad in identical white uniforms and have shaven heads to emphasize uniformity, likewise with police androids who wear black and monks who are robed. Instead of names, people have designations with three arbitrary letters (referred to as the "prefix") and four digits, shown on an identity badge worn at all times.

At their jobs in central video control centers, SEN 5241 and LUH 3417 keep surveillance on the city. LUH has a male roommate, THX 1138, who works in a factory producing android police officers. At the beginning of the story, THX finishes his shift while the loudspeakers urge the workers to "increase safety"—and congratulate them for only losing 195 workers in the last period—to the competing factory's 242.

On the way home, he stops at a confession booth in a row of many, and relates his concerns and mumbles prayers about "party" and "masses", under the Jesus Christ-esque portrait of "OMM 0000". A soothing voice greets THX, and OMM ends the confession with a parting salutation: "You are a true believer, blessings of the State, blessings of the masses. Work hard, increase production, prevent accidents and be happy."

At home, THX takes his drugs and watches holobroadcasts while engaging with a masturbatory device. LUH secretly substitutes pills in her possession for THX's medications, causing him to develop nausea, anxiety, and sexual desires. LUH and THX become involved romantically and have sex. THX later is confronted by SEN, who attempts to arrange that THX become his new roommate, but THX files a complaint against SEN for the illegal shift pattern change.

Without drugs in his system, THX falters during a critical and hazardous phase of his job, and a control center engages a "mind lock" on THX which raises the level of danger. After the release of the mind lock, THX makes the necessary correction to that work phase. THX and LUH are arrested and THX undergoes drug therapy, and one of his kidneys is removed for donation purposes. He enjoys a brief reunion with LUH, disrupted shortly after she reveals her pregnancy.

At THX's trial, it is stated that THX was clinically born. It is decided that it would be inefficient to terminate THX, so THX is sentenced to prison, alongside SEN. The prison appears to be an all white space with no walls. One of the prisoners is a "shell dweller", later called a "Wookiee". The other prisoners seem uninterested in escape. THX and SEN walk to search for an exit. They walk and walk, with only a white space to be seen all around them. Eventually they are joined by hologram actor SRT 5752, who starred in the holobroadcasts. SRT 5752 shows them the exit and suggests to them that they may have been going in circles. During the escape, THX and SRT are separated from SEN. Chased by the police robots, THX and SRT are trapped in a control center, from which THX learns that LUH has been "consumed", and her name has been reassigned to her fetus, numbered 66691, in a growth chamber. SEN eventually escapes to an area reserved for the monks of OMM, where a monk notices that SEN has no identification badge. SEN attacks him and later wanders into a child-rearing area, strikes up a conversation with children and sits aimlessly until police androids apprehend him. THX and SRT steal two cars. SRT struggles with figuring out how to drive the car. When SRT finally gets the car to move, SRT immediately crashes his car into a concrete pillar.

Pursued by two police androids on motorcycles, THX flees to the limits of the city and escapes into a ventilation shaft. The police androids pursue him on motorcycles along the shaft to an escape ladder, but are ordered by Central Command to cease pursuit, on the grounds that the expense of his capture exceeds their allocated budget for THX. The guards inform THX that the surface is uninhabitable in a last-ditch attempt to convince him to surrender, but he is undeterred and continues up the ventilation shaft. The city is then revealed to be entirely underground, and THX has escaped onto the surface, where he then witnesses the Sun setting.

Hans Memling's Christ Giving His Blessing (1478) is used as the visual representation of the state-sanctioned deity OMM 0000.

THX 1138 was the first film made in a planned seven-picture slate commissioned by Warner Bros. from the 1969 incarnation of American Zoetrope.[5][6] Lucas wrote the initial script draft based on his earlier short film, but Coppola and Lucas agreed it was unsatisfactory. Murch assisted Lucas in writing an improved final draft.[2][3] For some of SEN's dialogue in the film, the script included excerpts from speeches by Richard Nixon.[7]

The script required almost the entire cast to shave their heads, either completely bald or with a buzz cut. As a publicity stunt, several actors were filmed having their first haircuts/shaves at unusual venues, with the results used in a promotional featurette titled Bald: The Making of THX 1138. Many of the shaven-headed extras seen in the film were recruited from the nearby Synanon, an addiction recovery program which became a violent cult.[8]

Filming began on September 22, 1969.[9] The schedule was between 35 and 40 days, completing in November 1969. Lucas filmed THX 1138 in Techniscope.[2][10]

Most locations for filming were in the San Francisco area,[11] including the unfinished tunnels of the Bay Area Rapid Transit subway system,[2][11][12] the Lawrence Livermore National Laboratory,[2] the Marin County Civic Center in San Rafael designed by Frank Lloyd Wright,[12] the Lawrence Hall of Science in Berkeley,[12] the San Francisco International Airport,[12] and at a remote manipulator for a hot cell. Several scenes show a large IBM System/360 multi-computer installation.[13] Studio sequences were shot at stages in Los Angeles, including a white stage 100 by 150 feet (30 by 46 m) for the "white limbo" sequences.[2] Lucas used entirely natural light.[12]

Modified Lola T70s were used in the film.

The chase scene featured two Lola T70 Mk III race cars[14] being chased by Yamaha TA125/250cc two-stroke, race-replica motorcycles through two San Francisco Bay Area automotive tunnels: the Caldecott Tunnel between Oakland and Orinda; and the underwater Posey Tube between Oakland and Alameda.[2] According to Caleb Deschanel, cars drove at speeds of 140 miles per hour (230 km/h) while filming the chase.[2] Other cars appearing in several scenes of the movie include the custom-built Ferrari Thomassima cars; one of them is on display in the Ferrari museum in Modena, Italy.[15]

The chase featured a motorcycle stunt. Stuntman Ronald "Duffy" Hambleton (credited as Duffy Hamilton) rode his police motorcycle full speed into a fallen paint stand, with a ramp built to Hambleton's specification. He flew over the handlebars, was hit by the airborne motorcycle, landed in the street on his back, and slammed into the crashed car in which Duvall's character had escaped.[2] According to Lucas, it turned out Hambleton was perfectly fine, apart from being angry with the people who had run into the shot to check on him. He was worried that they might have ruined the amazing stunt he had just performed by walking into frame.

The then-uncompleted Transbay Tube served as the tunnel through which THX escapes.

THX's final climb out to the daylight was filmed (with the camera rotated 90°) in the incomplete (and decidedly horizontal) Bay Area Rapid Transit Transbay Tube before installation of the track supports, with the actors using exposed reinforcing bars on the floor of the tunnel as a "ladder".[2] The end scene, of THX standing before the sunset, was shot at Port Hueneme, California, by a second unit of (additional uncredited photographer) Caleb Deschanel and Matthew Robbins, who played THX in this long shot.[2]

After completion of photography, Coppola scheduled a year for Lucas to complete postproduction.[16] Lucas edited the film on a German-made K-E-M flatbed editor in his Mill Valley house by day, with Walter Murch editing sound at night; the two compared notes when they changed over.[2][16] Murch compiled and synchronized the sound montage, which includes all the "overhead" voices heard throughout the film, radio chatter, announcements, etc. The bulk of the editing was finished by mid-1970.

On completion of editing of the film, producer Coppola took it to Warner Bros., the financiers. Studio executives there disliked the film, and insisted that Coppola turn over the negative to an in-house Warner editor, who cut about four minutes of the film prior to release.[17]

The soundtrack to the THX 1138, conducted by Lalo Schifrin, was released in 1970. Recording took place on October 15 and 16, 1970, at The Burbank Studios in Burbank, California, U.S.[18]

Critic Roger Ebert praised the film's visuals.

THX 1138 was released to theaters on March 11, 1971 and was a commercial flop, earning back $945,000 in rentals for Warner Bros. but still leaving the studio in the red.[17] A contemporary survey found seven favorable, three mixed, and five negative reviews.[19]

Roger Ebert of the Chicago Sun-Times gave the film three stars out of four and wrote, "THX 1138 suffers somewhat from its simple storyline, but as a work of visual imagination it's special, and as haunting as parts of 2001: A Space Odyssey, Silent Running and The Andromeda Strain."[20] Gene Siskel of the Chicago Tribune awarded two stars out of four and stated, "The principal problem with this film is that it lacks imagination, the essential component of a science fiction film. Some persons might claim that the world of THX 1138 is here right now. A more reasonable opinion would hold that we are facing the problems of that world right now. Time has passed the film by."[21]

Vincent Canby of The New York Times wrote, "It is not, however, as either chase drama, or social drama, that THX 1138 is most interesting. Rather it's as a stunning montage of light, color and sound effects that create their own emotional impact ... Lucas's achievement in his first feature is all the more extraordinary when you realize that he is 25 years old, and that he shot most of the film in San Francisco, on a budget that probably would not cover the cost of half of one of the space ships in Stanley Kubrick's 2001."[22]

Arthur D. Murphy of Variety observed, "Likely not to be an artistic or commercial success in its own time, the American Zoetrope (Francis Ford Coppola group) production just might in time become a classic of stylistic, abstract cinema."[23] Charles Champlin of the Los Angeles Times praised the film as "a stunning deployment of the aural and visual resources of the screen to suggest a fearful new world of tyranny by technology," adding that "Lucas is obviously a master of cinematic effects with a special remarkable gift for discovering the look of the future in mundane places like parking structures and office corridors." Champlin stressed that the "real excitement of THX 1138 is not really the message but the medium—the use of film not to tell a story so much as to convey an experience, a credible impression of a fantastic and scary dictatorship of tomorrow."[24]

Kenneth Turan wrote in The Washington Post, "Fortunately, the film comes over not at all trite but rather as enormously affecting. Lucas obviously believed strongly in this futuristic vision, and the film draws its vitality and unity from his belief, and from the fact that it was not bottled up to meet arbitrary conditions but allowed the free rein necessary to reach completeness."[25] Penelope Houston of The Monthly Film Bulletin commented, "Details of the future society—control panels, monitor screens, soothing TV commercial voices, unshakeably calm robot policemen, the human animal turned automaton in appearance and function, but breaking out into a doomed love affair—are all tolerably persuasive, but in sum total rather a pile-up of predictability. On the Orwellian level of ideas, Lucas' passive new world is too indeterminate to carry enough conviction and, consequently, enough of a menacing charge."[26]

The film has continued to earn critical acclaim and holds an approval rating of 86% on Rotten Tomatoes based on 63 reviews, with an average score of 6.85/10. The consensus reads: "George Lucas' feature debut presents a spare, bleak, dystopian future, and features evocatively minimal set design and creepy sound effects."[27] On Metacritic it has a weighted average score of 75 out of 100 based on 8 reviews, indicating "generally favorable reviews".[28]

The film's title was reused as the name for Lucas's sound company, THX.

The significance of the name THX 1138 has been the subject of much speculation. In an interview for the DVD compilation Reel Talent, which included Lucas's original 4EB short, Lucas stated that he chose the letters and numbers for their aesthetic qualities, especially their symmetry.[38] According to the book Cinema by the Bay, published by LucasBooks, Lucas named the film after his telephone number while in college: 849-1138—the letters THX correspond to the numbers 8, 4, and 9 on the keypad.[39] However, Walter Murch states in the DVD's audio commentary that he always believed Lucas intended THX to be "sex", LUH to be "love", and SEN to be "sin".[7] John Lithgow, in "The Film School Generation" segment of the DVD series American Cinema, described the title THX 1138 as "reading like a license plate number."[40]

Numerous references to "1138" or "THX 1138" appear throughout the Star Wars films,[41] as well as other films by George Lucas. For example, THX 138 is the license plate number of John Milner's hot rod in American Graffiti. Lucas also founded THX Ltd., developer of the "THX" audio/visual reproduction standards.
