The Matrix is a 1999 science fiction-martial arts-action film written and directed by Larry and Andy Wachowski and starring Keanu Reeves, Laurence Fishburne, Carrie-Anne Moss, Joe Pantoliano, and Hugo Weaving. It was first released in the USA on March 31, 1999, and is the first entry in The Matrix series of films, comics, video games, and animation.

The film describes a future in which reality perceived by humans is actually the Matrix, a simulated reality created by sentient machines in order to pacify and subdue the human population while their bodies’ heat and electrical activity are used as an energy source. Upon learning this, computer programmer “Neo” is drawn into a rebellion against the machines. The film contains many references to the cyberpunk and hacker subcultures; philosophical and religious ideas; and homages to Alice’s Adventures in Wonderland, Hong Kong action cinema, Spaghetti Westerns, and Japanese animation.

Casting

Actor Will Smith turned down the role of Neo to make Wild Wild West. He later stated that, if given the role at that time, he “would have messed it up”. Nicolas Cage turned down the role because of “family obligations”. Janet Jackson turned down a role in the film because of previous obligations to go on tour.

Production design

In the film, the code that comprises the Matrix itself is frequently represented as downward-flowing green characters. This code includes mirror images of half-width kana characters and Western Latin letters and numerals. In one scene, the pattern of trickling rain on a window being cleaned resembles this code. More generally, the film’s production design placed a bias towards its distinctive green color for scenes set within the Matrix, whereas there is an emphasis on the color blue during the scenes set in the real world. In addition, grid-patterns were incorporated into the sets for scenes inside the Matrix, intended to convey the cold, logical, artificial nature of that environment.

The “digital rain” is strongly reminiscent of similar computer code in the film Ghost in the Shell, an acknowledged influence on the Matrix series. The linking of the color green to computers may have been intended to evoke the green tint of the older monochrome computer monitors.

Visual effects

The film is known for developing and popularizing the use of a visual effect known as “bullet time”, which allows the viewer to explore a moment progressing in slow-motion as the camera appears to orbit around the scene at normal speed.

One proposed technique for creating these effects involved propelling a high speed camera along a fixed track with a rocket to capture the action as it occurred. However, this was discarded as unfeasible, because not only was the destruction of the camera in the attempt all but inevitable, but the camera would also be almost impossible to control at such speeds. Instead, the method used was a technically expanded version of an old art photography technique known as time-slice photography, in which a large number of cameras are placed around an object and triggered nearly simultaneously. Each camera is a still-picture camera, and not a motion picture camera, and it contributes just one frame to the video sequence. When the sequence of shots is viewed as in a movie, the viewer sees what are in effect two-dimensional “slices” of a three-dimensional moment. Watching such a “time slice” movie is akin to the real-life experience of walking around a statue to see how it looks from different angles. The positioning of the still cameras can be varied along any desired smooth curve to produce a smooth looking camera motion in the finished clip, and the timing of each camera’s firing may be delayed slightly, so that a motion scene can be executed (albeit over a very short period of movie time).

Some scenes in The Matrix feature the “time-slice” effect with completely frozen characters and objects. Film interpolation techniques improved the fluidity of the apparent “camera motion”. The effect was further expanded upon by the Wachowski brothers and the visual effects supervisor John Gaeta so as to create “bullet time”, which incorporates temporal motion, so that rather than being totally frozen the scene progresses in slow and variable motion. Engineers at Manex Visual Effects pioneered 3-D visualization planning methods to move beyond mechanically fixed views towards more complicated camera paths and flexibly moving interest points. There is also an improved fluidity through the use of non-linear interpolation, digital compositing, and the introduction of computer generated “virtual” scenery.

The objective of the bullet time shots in The Matrix was to creatively illustrate “mind over matter” type events as captured by a “virtual camera”. However, the original technical approach was physically bound to pre-determined perspectives, and the resulting effect only suggests the capabilities of a true virtual camera.

The evolution of photogrametric and image-based computer-generated background approaches in The Matrix’s bullet time shots set the stage for later innovations unveiled in the sequels The Matrix Reloaded and The Matrix Revolutions. Virtual Cinematography (CGI-rendered characters, locations, and events) and the high-definition “Universal Capture” process completely replaced the use of still camera arrays, thus more closely realizing the “virtual camera”.

This film overcame the release of Star Wars Episode I: The Phantom Menace by winning the Academy Award for Visual Effects.

Music

The film’s score was composed by Don Davis. He noted that mirrors appear frequently in the movie: reflections of the blue and red pills are seen in Morpheus’s glasses; Neo’s capture by Agents is viewed through the rear-view mirror of Trinity’s motorcycle; Neo observes a broken mirror mending itself; reflections warp as a spoon is bent; the reflection of a helicopter is visible as it approaches a skyscraper. (The film also frequently references the book Alice’s Adventures in Wonderland, which has a sequel entitled Through the Looking-Glass.) Davis focused on this theme of reflections when creating his score, alternating between sections of the orchestra and attempting to incorporate contrapuntal ideas.

In addition to Davis’ score, The Matrix soundtrack also features music from acts such as Rammstein, Rob Dougan, Rage Against the Machine, Propellerheads, Ministry, Deftones, The Prodigy, Rob Zombie, Meat Beat Manifesto, and Marilyn Manson. Other pieces from artists such as Duke Ellington, Django Reinhardt, and Massive Attack are included in the film, but not featured on the soundtrack.
