Fourteen years before The Terminator (and only two years after HAL refused to open the pod door), there was another, lesser-known tale of a supercomputer seizing control of the world and trying to eradicate humanity. Engineer Dr. Charles A. Forbin, who convinces the U.S. Defense Department to let his "Colossus" control the country's nuclear arsenal, then watches in horror as his creation goes over his head and starts communicating with the Soviet's own electronic brain. Colossus is The granddaddy of all "computer run amok" films.
