WarGames is a 1983 American science fiction techno-thriller film written by Lawrence Lasker and Walter F. Parkes and directed by John Badham. The film, which stars Matthew Broderick, Dabney Coleman, John Wood, and Ally Sheedy, follows David Lightman (Broderick), a young hacker who unwittingly accesses a United States military supercomputer programmed to simulate, predict and execute nuclear war against the Soviet Union. WarGames was a critical and commercial success, grossing $125 million worldwide against a $12 million budget. The film was nominated for three Academy Awards. Plot During a surprise nuclear attack drill, many United States Air Force Strategic Missile Wing controllers prove unwilling to turn the keys required to launch a missile strike. Such refusals convince John McKittrick and other NORAD systems engineers that missile launch control centers must be automated, without human intervention. Control is given to a NORAD supercomputer known as WOPR (War Operation Plan Response, pronounced "whopper"), programmed to continuously run war simulations and learn over time. David Lightman, a bright but unmotivated Seattle high school student and hacker, uses his IMSAI 8080 computer to access the school district's computer system and change his grades. He does the same for his friend and classmate Jennifer Mack. Later, while war dialing numbers in Sunnyvale, California, to find a computer game company, he connects with a system that does not identify itself. Asking for games, he finds a list including chess, checkers, backgammon, and poker, along with titles such as "Theaterwide Biotoxic and Chemical Warfare" and "Global Thermonuclear War", but cannot proceed further. Two hacker friends explain the concept of a backdoor password and suggest tracking down the Falken referenced in "Falken's Maze", the first game listed. David discovers that Stephen Falken was an early artificial-intelligence researcher, and guesses correctly that the name of Falken's deceased son (Joshua) is the password. Unaware that the Sunnyvale phone number connects to WOPR at the Cheyenne Mountain Complex, David initiates a game of Global Thermonuclear War, playing as the Soviet Union while targeting American cities. The computer starts a simulation that briefly convinces NORAD military personnel that actual Soviet nuclear missiles are inbound. While they defuse the situation, WOPR nonetheless continues the simulation to trigger the scenario and win the game, as it does not understand the difference between reality and simulation. It continuously feeds false data such as Soviet bomber incursions and submarine deployments to NORAD, pushing them to increase
