From the back cover:
What mysterious power has drawn countless millions to see the impossible put on the screen? From the moment The Exorcist opened, a great debate has raged over the most successful movie ever made. Critics, clergy. And the public all have been split in their views. Now, for the first time, a book reveals the strange story of the writing of the novel and the making of the movie. It is the story of weird, almost inexplainable “coincidences” …of people doing things they had never dreamed of doing before …of levitation. A girl’s head rotation 180 degrees with the appropriate cracking sound, vomit hurled in people’s faces, demonic transformation, flying objects, apparitions, demon voices, superhuman feats of strength, not to mention the exorcism itself …of what happened to all those involved during the shooting of the movie …of how it changed their lives. It is a story even more fascinating …and thought-provoking …than The Exorcist itself.
