Scientists horrify us by reminding us of how zillions of mites crawl around our bodies and homes, however clean we try to keep things. We are just thankful that we can't see them. Movies are the same. There are pretty big mites crawling around on screen, but it is only our blissful ignorance that separates a horror movie from a war movie.
