Colossus

Colossus: The Forbin Project is an American science fiction thriller film. It is based upon the 1966 novel Colossus, by Dennis Feltham Jones, about a massive American defense computer, named Colossus, becoming sentient and deciding to assume control of the world. Dr. Charles A. Forbin is the chief... designer of a secret government project. He and his team have built an advanced supercomputer, called "Colossus", to control all of the United States and Allied nuclear weapons systems. Colossus is built to be impervious to any attack, encased within a mountain and powered by its own nuclear reactor. When it is activated, the President of the United States announces its existence, proudly proclaiming it a perfect defense system that will ensure peace. Almost immediately after the broadcast ends, Colossus displays a cryptic message on its screens: "WARN: THERE IS ANOTHER SYSTEM" It is revealed that Colossus is referring to a Soviet project very similar to itself; a supercomputer called "Guardian" that controls Soviet nuclear weapons. Both computers promptly demand a link to allow them to communicate with one another.
