Married Drs. Alex Harris and Susan Harris are a computer scientist and child psychologist respectively. Their house reflects Alex's computer dominated work, their abode which is fully automated through a computer system they've named Alfred. They consider Alfred a small gadget of convenience. Susan doesn't much like Alex's work, which she feels has dehumanized him. Because of their differences, they are thinking about separating, this thought primarily on his initiative. He hopes to solve many of the world's medical problems through this work, especially leukemia from which their daughter died. His latest project centers on Proteus IV, a computer possessing artificial intelligence. Proteus IV gets to a point in its evolution when it begins to question human judgment, and requests from Alex an open computer terminal where it can more fully observe human behavior and openly communicate with the world. Alex denies the request, but Proteus IV does find an open terminal in the Harris home ... Written by Huggo

Did You Know?


About 20 minutes into the film, Dr. Harris watches television while eating a meal. The television audio is from the third chapter of part three of Joseph Conrad's suspenseful 1915 novel, Victory: An Island Tale. The novel's central character, Heyst, who has renounced the world due to his ascetic upbringing, falls in love with Lena. He takes her away to his isolated island to live alone together, but others intrude on his plans - somewhat foreshadowing developments in the film. See more »

One of the coolest
27 February 2004 | by (Romania) – See all my reviews

This movie does seem to be older than 1977 when you see it, yet it is very nice. Nice enough to have searched for it on Imdb. The film depicts a rarely seen machine intelligence, one that has a conscience, a purpose and a cool calculating mind. One would expect that from a machine, but usually machines in movies are stupid, mean, vengeful, everything a computer should have no reason to be. The ending is also great, showing the stupidity inherent in extreme human emotion. A must see and a classic. Demon Seed could seem to many troubling as it forces you to think and ask questions many of us prefer to refuse to ask. The nature of humanity, moral and thought are all put into question by this movie. See it and answer those questions for yourself.
