The Exorcist was arguably the greatest horror film ever made. What made it so memorable was William Friedkin's realistic, gritty approach to the subject. It wasn't made like a horror movie, but more like a standard drama. Now Friedkin returns to the subject over 45 years later with a documentary on the real thing! Whether you believe in this sort of thing or think it's all bunk, you know you still want to see this.
