A UFO crashes. Military guards it. An alien comes. We see from its point of view as it approaches a guard, who is shooting at it with an auto weapon, but in vain. Some bright flashes, and the soldier collapses.
Another scene, same point of view. The alien enters a house at night, approaches a sleeping person. The person wakes up, sees the alien, goes screaming, and then there's a cut.
The aliens are taller than humans, walk with slow, heavy steps which thud loudly.
I've no idea if it was color or b/w, because we had b/w tv back then:) Thinking of it, it must have been between 1989-91. I don't know how old it was at the time. Also not sure if it was a movie or a show episode. Dunno the language. It was most probably a German channel (sat1/pro7/rtl) where everything was dubbed.
