there exist a tiny subgenre of def con movie and sort of disaster movie with nuclear defense system go haywire represent fail safe and dr. strangelove and war game and by dawn early light . and the little known 1970 colossus and in which two computer supervise the missile arsenal link up and get smart . this film be often call date and but to my eye it have stand the test of time very well . like in andromeda strain ( 1971 ) all the money be in the set and the actor be inexpensive unknown . unlike most old scifi tales this one isn not about robot or space exploration and but about computer and data link and electronic surveillance . that be why the frightening colossus scenario be actually more plausible today . mostly this film be about technician communicate with a computer while minimal human interest subplot and no chase or gunfight and just the scifi scenario . that the way i like it . i be very happy that colossus represent the forbin project be finally available widely on vhs and dvd . maybe now it find it audience and it certainly deserve that . after see this film and interact with your computer may feel somehow . different .
