The Matrix is a 1999 science fiction action film written and directed by the Wachowskis.[a] It is the first installment in the Matrix film series, starring Keanu Reeves, Laurence Fishburne, Carrie-Anne Moss, Hugo Weaving and Joe Pantoliano, and depicts a dystopian future in which humanity is unknowingly trapped inside the Matrix, a simulated reality that intelligent machines have created to distract humans while using their bodies as an energy source. When computer programmer Thomas Anderson, under the hacker alias “Neo”, uncovers the truth, he joins a rebellion against the machines along with other people who have been freed from the Matrix.

The Matrix is an example of the cyberpunk subgenre of science fiction. The Wachowskis’ approach to action scenes was influenced by anime and martial arts films (particularly fight choreographers and wire fu techniques from Hong Kong action cinema); other influences include Plato’s cave and 1990s Telnet hacker communities. The film popularized terms such as the red pill, and introduced a visual effect known as “bullet time”, in which the heightened perception of certain characters is represented by allowing the action within a shot to progress in slow motion while the camera appears to move through the scene at normal speed, allowing the sped-up movements of certain characters to be perceived normally.

At an abandoned hotel, a police squad corners Trinity, who overpowers them with superhuman abilities. She flees, pursued by the police and a group of suited Agents capable of similar superhuman feats. She answers a ringing public telephone and vanishes.

Computer programmer Thomas Anderson, known by his hacking alias “Neo”, is puzzled by repeated online encounters with the phrase “the Matrix”. Trinity contacts him and tells him a man named Morpheus has the answers Neo seeks. A team of Agents and police, led by Agent Smith, arrives at Neo’s workplace in search of him. Though Morpheus attempts to guide Neo to safety, Neo surrenders rather than risk a dangerous escape. The Agents offer to erase Neo’s criminal record in exchange for his help with locating Morpheus, who they claim is a terrorist. When Neo refuses to cooperate, they fuse his mouth shut, pin him down, and implant a robotic “bug” in his abdomen. Neo wakes up from what he believes to be a nightmare. Soon after, Neo is taken by Trinity to meet Morpheus, and she removes the bug from Neo.

Morpheus offers Neo a choice between two pills: red to reveal the truth about the Matrix, or blue to make Neo forget everything and return to his former life. Neo takes the red pill, and his reality begins to distort until he awakens in a liquid-filled pod among countless other pods, containing other humans. He is then brought aboard Morpheus’s flying ship, the Nebuchadnezzar. As Neo recuperates from a lifetime of physical inactivity in the pod, Morpheus explains the history: in the early 21st century, humanity had developed intelligent machines before war broke out between the two sides. After humans blocked the machines’ access to solar energy, the machines responded by enslaving humankind and harvesting their bioelectric power while keeping their minds pacified in the Matrix, a shared simulated reality modeled on the world as it was in 1999. In the years following, the remaining free humans took refuge in the underground city of Zion.
