I have asked about this before several years ago without luck so here goes again. I remember seeing an old (1930s?) horror movie on british TV which used the same device repeatedly throughout whereby just before an awful murder / unpleasantness, the characters would turn to each other and say stuff like "What did you say?", "what's that?", "Eh?", "Hmm?" - you know, give the impression that the other character with them had said something even though they hadn't made a sound. It was an incredibly creepy and unnerving way of announcing that something bad was about to happen. There are no noises, so not like a corny Abbott and Costello - the fact that there was no noise prior to the characters asking each other was what made it so creepy. I would dearly love to identify this movie. Many thanks
