Wes Craven's first commercial feature was a grisly horror film about some young girls who were raped and dismembered within 100-feet of their home. Shortly after the movie's release, Craven attended a dinner party. He found himself seated beside another guest whom he had never met and was introduced as a budding film director "who has just made a movie." Which movie, he was asked. "Last House on the Left," he reluctantly replied -- whereupon the other guest silently rose from the table and moved to another seat.
[This sort of thing, Craven confessed, was a regular occurance.]
