WarGames is a 1983 drama-thriller film written by Lawrence Lasker and Walter F. Parkes and directed by John Badham. The film starred Matthew Broderick in his second major film role, and featured Ally Sheedy, Dabney Coleman, John Wood, and Barry Corbin.

The film follows David Lightman (Broderick), a young hacker who unwittingly hacks into 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.
