In the far future, a research station on Saturn 3 is home to Adam and Alex, two lovers working on a way to feed the teeming masses of Earth . Their life together is interrupted by Captain James and his helper robot, Hector, who arrive just before Saturn 3 goes into eclipse. With all communications to the outside cut off for the next 23 days, it is lucky that the captain is in no way insane and his robot has been programmed to resist the urge to go on a murderous rampage.
This movie has an awful reputation, but its actually not that bad, given the synopsis in the previous paragraph. The plot contains some interesting ideas and the characters are surprisingly well drawn. Farrah Fawcett is not much of an actor. but Alex is a stronger character than might be expected in a film where she is the main source of rivalry between the two males. The script is a bit of a mixed bag, but the story is strong enough to smooth over some of the more ropey dialog. The real star of the show is the production design, the sets in particular look fantastic, and the robot is suitably sinister even if some of the special effects are a little non-special.
Recommend if you like this sort of thing. IMDB
