The Forbin Project

Colossus: The Forbin Project (also known as The Forbin Project) is a 1970 American science fiction thriller film from Universal Pictures, produced by Stanley Chase, directed by Joseph Sargent, that stars Eric Braeden, Susan Clark, Gordon Pinsent, and William Schallert. It is based upon the 1966 science fiction novel Colossus by Dennis Feltham Jones.[1]

The film is about an advanced American defense system, named Colossus, becoming sentient. After being handed full control, Colossus' draconian logic expands on its original nuclear defense directives to assume total control of the world and end all warfare for the good of humankind, despite its creators' orders to stop.[2]

Dr. Charles A. Forbin is the chief designer of a secret project, "Colossus", an advanced supercomputer built to control the United States and Allied nuclear weapon systems. Located deep within a mountain and powered by its own nuclear reactor, Colossus is impervious to any attack. After Colossus is fully activated, the president of the United States proudly proclaims that Colossus is "the perfect defense system".

Colossus' first action is a message warning: "THERE IS ANOTHER SYSTEM" and giving its coordinates. CIA Director Grauber is asked why the CIA did not know this, but Grauber responds that they had seen indications of a large Soviet
defense project but did not know what it was. Forbin is asked how
Colossus deduced the other system's existence, to which Forbin answers
"Colossus may be built better than we thought." Shortly thereafter, the
Soviets announce that their "Guardian" system is now operational.

Colossus requests to be linked to Guardian. The President allows
this, hoping to determine the Soviet machine's capability. The Soviets
also agree to the experiment. Surprising everyone, Colossus and Guardian
begin to slowly communicate using arithmetic. Even more surprising, the
two systems' communications quickly evolve to complex mathematics far
beyond human comprehension
