For me it was "Communion". There is a scene where Christopher Walken is lying is bed and he's looking at his bedroom door. Evereyone else in asleep and he just stares at the door. Then he says "I can see you", the camera shifts slightly and you see a stereotypical gray alien peeking round the door. Scared the hell out of me when I was in my easrly teens. Not least because it is based on the supposedly real life experiences of Whitley Streiber. The idea that you'd wake up in the middle of the night, find everyone else asleep/paralysed and the aliens come to kidnap you from your bed...! *shiver*
Oh, another one. In "Wolfen" (coincidentally based on a novel by Whitley Streiber), which is a film about a detective hunting what are essentially werewolves in some big American city, there is a scene with the hero (Albert Finney) sitting in his car in the rain. He comes to realise that on a wall a liitle in front of him is one of the creatures. He very slowly reaches out to turn on his windscreen wipers/headlights for a better look and the instant he does it, the animal vanishes. Very effective at suggesting the animals are very clever and alert...and extraordinarily fast and powerful. Enough to wig me out as a kid.
