Please, anybody, help with the title for a sc-fi!
Quite a few years ago I watched a TV program devoted to horror / sci-fi movies dealing with aliens. There a number of extracts were shown from all manner of such films (including "Xtro"). One of them showed a man in a very large white room (perhaps it was inside a UFO). The man was attacked by some ball of steel that was flying in the air - as it flew towards the man, a kind of blade sprung from it, and as this ball was passing the man's head, the blade sliced a piece of man's ear off. Then it changed its direction and again flew towards the man, attacking with another blade. What freaky horror / sci-fi movie has these scenes? Does anybody know? I keep wondering for quite a while.
Thanks in advance.
