Tron

Tron is a 1982 American science fiction action adventure film written and directed by Steven Lisberger from a story by Lisberger and Bonnie MacBird. The film stars Jeff Bridges as Kevin Flynn, a computer programmer and video game developer who is transported inside the software world of a mainframe computer where he interacts with anthropomorphic programs in his attempt to escape. It also stars Bruce Boxleitner (in the titular role), David Warner, Cindy Morgan, and Barnard Hughes. Tron was one of cinema's earliest films to use extensive computer-generated imagery (CGI).

The inspiration for Tron dates back to 1976, when Lisberger became intrigued with video games after seeing Pong. He and producer Donald Kushner set up an animation studio to develop Tron with the intention of making it an animated film. To promote the studio itself, Lisberger and his team created a 30-second animation featuring the first appearance of the title character. Eventually, Lisberger decided to include live-action elements with both backlit and computer animation for the actual feature-length film. Various studios had rejected the storyboards for the film before Walt Disney Productions agreed to finance and distribute Tron. There, backlit animation was finally combined with the 2D computer animation and the live-action footage.

Tron was released on July 9, 1982. The film was a moderate success at the box office, and received mixed reviews from critics, who praised its groundbreaking visuals and acting but criticized its storyline as being incoherent. Tron received nominations for Best Costume Design and Best Sound at the 55th Academy Awards. It was however disqualified from the Best Visual Effects category because at the time the Academy of Motion Picture Arts and Sciences felt that using computer animation was "cheating". Tron spawned multiple video games (including an arcade tie-in released shortly after the film) and, as it became a cult film, a multimedia franchise including comic books. A sequel titled Tron: Legacy, directed by Joseph Kosinski, was released in 2010, with Bridges and Boxleitner reprising their roles and Lisberger acting as producer. A commercial success, it was followed by the Disney XD animated series Tron: Uprising in 2012, set between the two films. A third installment, Tron: Ares, was released on October 10, 2025, and also featured the continued involvement of Bridges and Lisberger.

Kevin Flynn is a leading software engineer, formerly employed by large technology corporation ENCOM. He now runs a video game arcade, and attempts to hack into ENCOM's system with a program called CLU. However, ENCOM's Master Control Program (MCP) halts his progress and CLU is deleted. Within ENCOM, programmer Alan Bradley and his girlfriend, engineer Lora Baines, discover that the MCP has closed off their access to projects. When Alan confronts the senior executive vice president, Ed Dillinger, he asserts the security measures are an effort to stop the hacking attempts. However, when Dillinger privately questions the MCP through his computerized desk, he realizes the MCP has expanded into a powerful virtual intelligence and has been illegally appropriating personal, business, and government programs to increase its own capabilities. As Dillinger rose to the top of ENCOM by presenting Flynn's games as his own, the MCP blackmails Dillinger by threatening to expose his plagiarism if he does not comply with its directives.

Lora deduces that Flynn is the hacker, and she and Alan go to his arcade to warn him. Flynn reveals that he has been trying to locate evidence proving Dillinger's plagiarism. Together, the three form a plan to break into ENCOM and unlock Alan's "Tron" program, a self-governing security measure designed to protect the system and counter the functions of the MCP. Once inside ENCOM, the three split up, and Flynn comes into direct conflict with the MCP through a laboratory terminal. Before Flynn can get the information he needs, the MCP uses an experimental laser to digitize and upload him into the ENCOM gaming grid. There, computer programs are living entities appearing in the likeness of the human "Users" (programmers) who created them. The space is ruled by the MCP and its second-in-command, Sark, who coerce programs to renounce their belief in the Users and force those who resist to compete in deadly games.

Flynn is put into the games and plays well; between matches, he befriends two other captured programs, Ram and Tron. The three escape into the system during a round of Light Cycle (an arcade game Flynn created and is skilled at), but Flynn and Ram become separated from Tron by an MCP pursuit party. While attempting to help a badly injured Ram, Flynn learns that he can manipulate portions of the system by accessing his programmer knowledge. Just before Ram "derezzes" (dies), he recognizes Flynn as a User, and encourages him to find Tron and free the system. Using his newfound ability, Flynn rebuilds a broken vehicle and disguises himself as one of Sark's soldiers.

Tron enlists help from Yori, a sympathetic program, and at an I/O tower receives information from Alan necessary to destroy the MCP. Flynn rejoins them, and the three board a hijacked solar sailer to reach the MCP's core. However, Sark's command ship destroys the sailer, capturing Flynn and Yori and presumably killing Tron. Sark leaves the command ship and orders its deresolution, but Flynn keeps it intact by manipulating the system again.

Sark reaches the MCP's core on a shuttle carrying captured programs deemed powerful or useful. While the MCP attempts to absorb these programs, Tron, who is still alive, confronts Sark and critically injures him, prompting the MCP to give Sark all its functions. Realizing that his ability to manipulate the system might give Tron an opening, Flynn leaps into the beam of the MCP, distracting it. Seeing a break in the MCP's shield, Tron attacks through the gap and destroys the MCP and Sark, ending the MCP's control over the system and allowing the captured programs to communicate with users again.
