Howdy,
well, I wanted to know if you remember this movie, i'll just throw a few highlights and you gimme the name:
timeline: it's from the 80's
plot: A husband leaves for a bizz trip and leaves his wife in their hightech house, the cpu that guards the house comes alive and starts to build himself a body. [suspension builds] tries to kill the wife... etc etc
scenes I remember: the part that the robot caught the wife and tied her down and slowly starts to cut her skirt from the end to top with a round saw while the husband tries to break into the house and rescue...
How the computer built itself from scrap around the house.
Downside: only the familiar one, the ol' dissapointment-of-watching-the-movie-i-loved-a-decade-later-to-find-out-it's-not-all-that.
Well, do you remeber the name of the movie?
