The Movie That Started It All

In War Games, the US Department of Defense's supercomputer goes rogue and is about to start launching nuclear weapons at the Soviet Union. At NORAD, buried deep inside Cheyenne Mountain, the entire US nuclear command is trying to figure out how to stop the computer from starting a nuclear war. The world's only hope? David Lightman played by National Treasure Matthew Broderick. And eventually he comes up with a solution that kind of stymies the computer - playing tic-tac-toe.
