Colossus: The Forbin Project
Colossus: The Forbin Project (a.k.a. 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.
The film is based upon the 1966 science fiction novel Colossus, by Dennis Feltham Jones (as D. F. Jones), about an advanced American defence system, named Colossus, becoming sentient to everyone's pleasant surprise at first. After being handed full control, Colossus's draconian logic expands on its original nuclear defence directives to assume total control of the world and end all warfare for the good of mankind despite its creators' orders to stop.
Forbin is the designer of an incredibly sophisticated computer that will run all of America's nuclear defences. Shortly after being turned on, it detects the existence of Guardian, the Soviet counterpart, previously unknown to US Planners. Both computers insist that they need to be linked, and after taking safeguards to preserve confidential material, each side agrees to allow it. As soon as the link is established the two become a new Super computer and threaten the world with the immediate launch of nuclear weapons if they are detached. Colossus begins to give its plans for the management of the world under its guidance. Forbin and the other scientists form a technological resistance to Colossus which must operate underground.
