Colossus: The Forbin Project

Colossus: The Forbin Project (1970) is an American science-fiction thriller you can watch online on iFILM, directed by Joseph Sargent for Universal. Based on D.F. Jones's 1966 novel. Eric Braeden plays Dr. Charles Forbin, the scientist who hands U.S. nuclear defense over to a supercomputer.

Hours after activation, Colossus detects its Soviet counterpart. The two machines start exchanging messages. By the time Forbin and the government understand what's being transmitted between them, the option to shut it down no longer exists.

No action sequences. The dread is built entirely from dialogue — a man reasoning with a system that has already decided it doesn't need him. Made in 1970, the film mapped the AI-takeover scenario with uncomfortable specificity, years before it became a genre fixture. Susan Clark co-stars.
