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),[1] about an advanced American defense 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 defense directives to assume total control of the world and end all warfare for the good of mankind despite its creators’ orders to stop.[2]
