WarGames is a 1983 American Cold War science-fiction film written by Lawrence Lasker and Walter F. Parkes and directed by John Badham. The film stars Matthew Broderick, Dabney Coleman, John Wood, and Ally Sheedy.
The film follows David Lightman (Broderick), a young hacker who unwittingly accesses WOPR, a United States military supercomputer programmed to predict possible outcomes of nuclear war. Lightman gets WOPR to run a nuclear war simulation, originally believing it to be a computer game. The simulation causes a national nuclear missile scare and nearly starts World War III.
