I want to test your memory.
Back in the middle 1960's I saw the scariest movie on TV that I ever saw. It was B&W and probably a B movie. The name I remember which is obviously wrong was Fahrenheit 454. I think it was B&W but it could have been a B&W TV I was watching, but I think they all were back then?
Now the only clue to the movie I can provide with any accuracy is: people ran into an old farm house chased by aliens or robots that looked like inverted aluminum funnels, large at the bottom and small at the top. These funnels shot fire out of there tops at the people and I seem to remember that the only way they escaped was the floor could not hold the weight of the robots and they fell through the floor into the basement and the people ran away.
Now I only saw it once. It scared the heck out of me. And I have been trying to find it on and off ever since with no luck.
Does anyone have any ideas?
