I just found a huge article on the use of the Telephone in Slasher Movies. Not something I would have ever even thought about before, but after reading this story, it all makes sense now. check out an excerpt below and links to the full article….
The telephone’s influence is so pervasive that only when things go wrong with the technology – for example, a thunderstorm renders it inoperative – do our problem of isolation becomes apparent. Suddenly we cannot call the police or the ambulance for help, and friends who might otherwise provide companionship and advice become unreachable. Isolated, we find ourselves at our most vulnerable – and if it’s the killer who has cut the line, then we also feel a sense of threat.
