Demon Seed tells of the impregnation of a female by a master computer system which seeks to perpetuate itself in human form. Julie Christie stars as the electronic Eve, along with Fritz Weaver as her scientist husband.
Excellent performances and direction (Donald Cammell), from a most credible and literate screenplay [from a novel by Dean R. Koontz], make production an intriguing achievement in story-telling.
Christie and Weaver live adjacent to an advanced computer center. Their marriage is crumbling because of his commitment to a new machine, Proteus IV, designed to do almost everything but think.
The burden of the story falls on Christie and she does indeed make the film come off.
