Johnny Mnemonic is a 1995 cyberpunk action film directed by Robert Longo in his feature directorial debut, adapted by William Gibson from his 1981 short story. It stars Keanu Reeves, Dolph Lundgren, Takeshi Kitano, Ice-T and Dina Meyer, and features Denis Akiyama, Udo Kier, Henry Rollins, and Barbara Sukowa in supporting roles.

The film, set in 2021, portrays a dystopian future racked by a tech-induced plague, awash with conspiracies, and dominated by megacorporations and organized crime. The story follows Johnny (Reeves), a data courier with an overloaded brain implant designed to securely store confidential information. The head of a yakuza-affiliated megacorporation (Kitano) attempts to suppress the data.

The film was a Canadian and American co-production, filmed in Toronto and Montreal. The project was difficult for Gibson and Longo. After they struggled for years to finance a low-budget adaptation of Gibson's story, Sony greenlit Johnny Mnemonic with a $26 million budget. When Reeves' previous film, Speed, unexpectedly became a major hit, Sony attempted to retool Johnny Mnemonic as a blockbuster. Longo experienced extensive creative differences with the studio, who forced casting choices and script rewrites on him. The film was ultimately recut without Longo's involvement, resulting in a version that he felt did not reflect his artistic vision. Described by Longo and Gibson as originally full of irony, it was edited into a mainstream action film and received negative reviews from critics. Nonetheless, it has developed a cult following.

A longer version (103 mins) of the film premiered in Japan on April 15, 1995, featuring an alternate musical score and more scenes involving Kitano. The film was released in the United States on May 26, 1995. In 2022, a black-and-white edition of the film, titled Johnny Mnemonic: In Black and White was released, which Longo characterized as closer to his original vision.

Plot In 2021, society is driven by a virtual Internet, which has created a degenerative effect called "nerve attenuation syndrome" or NAS. Megacorporations control much of the world, intensifying the class hostility already created by NAS.

Johnny is a "mnemonic courier" who discreetly transports sensitive data for corporations in a storage device implanted in his brain at the cost of his childhood memories. His current job is for a group of scientists in Beijing. Johnny initially balks when he learns the data exceeds his memory capacity even with compression, but he agrees given the large fee will cover the cost of the operation to remove the device. Johnny keeps it secret that he is overloaded; he must have the data extracted within a few days or suffer fatal brain damage and corrupt the data. The scientists encrypt the data with three random images from a television feed. As they transmit these images to the receiver in Newark, New Jersey, they are attacked and killed by yakuza led by Shinji, who wields a laser whip. Johnny battles the yakuza, grabs a fragment of the encryption key images, and escapes. Shinji reports his failure to his superior, Takahashi. Their conversation reveals the yakuza are working on behalf of Pharmakom, a megacorporation. Johnny witnesses brief projections of a female artificial intelligence who attempts to aid him, but he dismisses her. The AI is later identified as Anna Kalmann, Pharmakom's former CEO and founder who became an AI upon her death.

In Newark, Johnny meets with his handler Ralfi, who betrays him. Johnny is rescued from the yakuza by Jane, a cybernetically-enhanced bodyguard; members of the LoTeks, an anti-establishment group; and the LoTeks' leader, J-Bone. Ralfi is sliced into pieces when he gets in Shinji's way. Jane takes Johnny to Spider, the doctor who installed Jane's implants. At a clinic, Spider reveals his medical charity was intended to receive the Beijing scientists' data, which is a stolen cure for NAS. Spider claims Pharmakom refuses to release the cure because they are profiting off mitigation treatments. The portion of the encryption images Johnny took plus the piece Spider received are insufficient to decrypt Johnny's mind, so Spider suggests they see Jones at the LoTeks' base. Suddenly, an assassin hired by Takahashi known as "The Street Preacher" attacks them, killing Spider as Johnny and Jane escape.

The two reach the LoTek base and learn from J-Bone that Jones is a dolphin once used by the Navy that can help decrypt Johnny's payload. As they start the procedure, Shinji and the yakuza attack the base. Takahashi appears and confronts Johnny, holding him at gunpoint. At the same time, Anna appears and confirms that Pharmakom already had a cure for NAS before Takahashi's young daughter died from the condition eight months prior; Anna is helping out of disgust with her company's actions. Shinji, in a surprise betrayal, shoots Takahashi. Johnny and Shinji fight, culminating with Johnny killing Shinji. Before he dies, Takahashi has a change of heart and turns over a portion of the encryption key to Johnny. This still is not enough to fully decrypt the data. J-Bone tells Johnny that he will need to hack his own mind with Jones' help. Johnny, Jane, J-Bone and the LoTeks defeat the remaining forces sent after them. The Street Preacher arrives, and, after a fight, is electrocuted to death by Johnny and Jane.

The second attempt starts, and aided by Anna, Johnny decrypts the data and simultaneously recovers his childhood memories which reveals that Anna is his mother. As J-Bone transmits the NAS cure information across the internet via pirate broadcasts, Johnny and Jane watch from afar as the Pharmakom headquarters goes up in flames. In celebration, J-Bone disposes of the Street Preacher's burnt corpse by tossing it into the waters of Newark.

Cast

Development In the 1980s, director Robert Longo was known primarily for his artwork, including "Men in the Cities", a series of images meant to be viewed sequentially. After having been influenced by film, he transitioned to directing music videos and, when he tired of that, became interested in adapting William Gibson's Johnny Mnemonic. Longo and Gibson first started work on a screenplay in 1989. Longo's first attempt to finance the film was through Warner Bros. in 1990. Bob Krasnow liked Longo's short film, Arena Brains, and offered to finance a feature film. Before pre-production could begin, Warner Bros. merged with Time Inc., and the film was put on hold. Recognizing the film was unlikely to be produced, Krasnow let Longo out of his contract. Longo nearly gave up on getting Johnny Mnemonic made but continued to make contacts in Hollywood.

Longo and Gibson sought to sell Johnny Mnemonic as an art film on a small budget but failed to get financing from the studios. Gibson said they wanted to avoid flashy, MTV-inspired visuals and "plunge the audience into a very strange but consistent universe". Longo commented that the project "started out as an arty 1½-million-dollar movie, and it became a 30-million-dollar movie because we couldn't get a million and a half." Longo's lawyer suggested that their problem was that they were not asking for enough money and that studios would not be interested in such a small project. Studios were also concerned that Longo's artistic background would impact his ability to make a commercially viable film.

The unbounded spread of the Internet in the early 1990s and the consequent rapid growth of high technology culture had made the cyberpunk genre increasingly relevant, and this was a primary motivation for Sony Pictures's decision to fund the project in the tens of millions. Val Kilmer was originally cast in the title role, and Keanu Reeves replaced him when Kilmer dropped out. Gibson approved of this casting and said Reeves understood the character well. Reeves' Canadian nationality opened up further financial options, such as Canadian tax incentives. In Canada, Longo discovered he had to maintain Canadian crew quotas. Michael Chapman had agreed to shoot the film, but Longo had to hire a Canadian cinematographer instead.

Production

Pre-production When Reeves' previous film, Speed, turned into a major hit in 1994, expectations were raised for Johnny Mnemonic, and Sony saw the film as a potential blockbuster hit. Gibson said Sony executives began pressing them about whether their film had busses or explosions, critical elements of Speed.

Longo's experiences with the financiers were poor, believing that their demands compromised his artistic vision. Many of the casting decisions, such as Lundgren, were forced upon Longo to increase the film's appeal outside of the United States. Longo and Gibson, who had no idea what to do with Lundgren, created a new character for him. Lundgren had previously starred in several action films that emphasized his physique. He intended the role of the street preacher to be a showcase for further range as an actor, but his character's monologue was cut during editing. Gibson said that the monologue, a sermon about transhumanism that Lundgren delivered naked, was cut due to fears of offending religious groups. Kitano was cast to appeal to the Japanese market. Rollins, who is uninterested in science fiction, joined the cast because he liked the film's focus on an upcoming disadvantaged underclass.

The film significantly deviates from the short story, such as turning Johnny, not his bodyguard, into the primary action figure. Molly Millions is replaced with Jane, as the film rights to Molly had already been sold. Gibson did not want Molly in the film, though, and thought it would be best to reserve her for a different franchise. Nerve attenuation syndrome (NAS) is a fictional disease that is not present in the short story. NAS, also called "the black shakes", is caused by an overexposure to electromagnetic radiation from omnipresent technological devices and is presented as a raging epidemic. In the film, one pharmaceutical corporation has found a cure but chooses to withhold it from the public in favor of a more lucrative treatment program. References to Jones the dolphin's heroin addiction was one of many plot elements cut during editing.

Design and visual effects The film is noted for its use of computer-generated imagery to realize its virtual reality sequences. Three different visual effects teams were employed to create the film's effects. The climatic sequence was designed by illustrator Rick Berry, who had previously designed book covers for Gibson."Featured Art by Rick Berry". DarkEcho (darkecho.com). Other effects were created by Sony Pictures Imageworks, Fantasy II Film Effects, and C.O.R.E. Digital Pictures.

Concept artist Syd Mead designed Jones' cybernetic implants.

Filming Shooting took place in Toronto, where Longo temporarily moved his family, and Montreal. Shooting locations included Casa Loma, The Opera House, Spadina House, Union Station, and the Jacques Cartier Bridge.
