WarGames is a 1983 American techno-thriller film directed by John Badham, written by Lawrence Lasker and Walter F. Parkes, and starring Matthew Broderick, Dabney Coleman, John Wood, and Ally Sheedy. Broderick plays David Lightman, a young computer hacker who unwittingly accesses a United States military supercomputer programmed to simulate, predict and execute nuclear war against the Soviet Union, triggering a false alarm that threatens to start World War III.

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.
