Storyline

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

Though-provoking all the way to its great ending.
14 February 2002 | by See all my reviews

This visionary and scary sci-fi thriller was somewhat coldly directed, but the extremely thought-provoking (and provocative) script ("what if...this could happen one day"), some unusually intelligent dialogue ("eternity does exist, but the price of admission, death, is too high for me to pay") and Julie Christie's tense performance make this film worth watching. Plus, the voice of the computer (Robert Vaughn) is suitably both calm and menacing. (***)
