I met Kevin Williamson years ago and he told me that he got the idea to write the opening scene of "Scream" when he was house sitting one night, the weather was bad and somebody started calling on the phone and hanging up. Years before that incident in 1979, the great Carol Kane played a babysitter that was being harassed on the telephone by a stranger and the beginning of the film produced one of the scariest twists ever to populate a scary movie.
