This film is an overlooked classic. Very rarely seen on TV. It is both a science fiction tale and a Cold War drama. The United States creates a super computer to control its defence systems. This advanced machine has its own intelligence so that it can absorb the mass of data required to manage the nuclear arsenal. Dr Charles Forbin the creator of this computer called Colossus. Forbin is soon informed that there is another system created in the Soviet Union called Guardian and both computers start communicating with each other. The computers start dictating terms/ making demands of their human masters. Forbin is charged with stopping the machines before its too late. What is chilling is that the computers are far more smarter than the humans and things get very tricky. I can't say anymore, give this is go. This film is the forerunner for films like The Matrix and The Terminator. Great stuff.
Great movie, still relevant today I just saw this movie for the first time, and it is an intelligent and well-done sci-fi thriller. It deals with AI sentience, and almost can be seen as the beginnings of Gort (from another excellent sci-fi film from 1951 called The Day The Earth Stood Still)\ \ If you're not sure about watching this, just watch it, you might be surprised and find a hidden, thought-provoking, gem!
