This horror movie, The Exorcist, at the time was unheard of because it was so intense. Every horror movie fan couldn\"t help but see this horror film and fear it. I love the film like so many other fans of the genre and thought it needed to be on the site. Check out the trailer as this movie needs very little introduction.
