Fritz Weaver is a brilliant scientist named Alex Harris who develops an organic super computer he calls Proteus 4. Over time the computer starts to develop a mind of it's own.
It refuses to do certain things and also has a growing interest in humans. it takes a bizarre liking to Harris' wife Susan (Julie Christie).
Susan and Alex have a failing marriage and Alex moves out. Their home is completely computer controlled, which is bizarre in and of itself. This allows the Proteus 4 to completely take over the home and keep Susan as a prisoner.
Susan soon learns that the Proteus 4 wants to impregnate her and live forever thru the offspring. Life is turned into a living hell for Susan who is brainwashed by the computer, tied to a bed and Proteus does his thing.
The ending is a bizarre and somewhat twisted one that you really have to see to believe. I first saw this on VHS many, many years ago a recalled liking it very much.
The Blu-ray from Warner Archive is beautiful and a pleasant surprise. I found the movie to be just as good as I remember. Weaver is always good in anything he does and Christie looks as beautiful as ever.
There are several shocking scenes in this film and I highly recommend this thriller. The rest of the cast is rounded out by Gerrit Graham, Berry Kroeger and Lisa Lu.
A big thanks to Warner Archive for bringing this to Blu-ray.
