The Exorcist begins with a character you won’t even see again until near the end of the film. The film starts with Father Lankester Merrin (Max von Sydow) on an archeological dig in Iraq. In a scene that involves more sights and sounds than words, you see Merrin uncover an amulet which resembles a demon Merrin defeated in an exorcism years ago. The exorcism lasted several days and nearly killed Merrin. The demon he exorcised was called Pazuzu.
As this story progresses, we simultaneously meet Father Damien Karras. Karras is a priest and a psychiatrist. He is a firm believer in modern science and he disbelieves things like exorcism. In his story, Karras's mother dies without Karras being able to help her and that causes him to lose his faith in God.
What Made This Film So Special
The Exorcist is perhaps the best example of how 1970’s films were different than today because there are so many films we can compare to it. Indeed, you can’t really find a modern exorcism movie which isn’t essentially a direct copy of The Exorcist. Yet, all of them fail to live up to the original. And the reason all the imitators fail, despite having so many advantages, such as having a success to study and the benefit of being able to go further in terms of effects and scares with modern audience, is exactly what makes The Exorcist the great film it is.
This film worked because it was a story about several people who endure horrific choices and incredible suffering. It was not a film about two priests fighting a demon. That is what makes this film so unforgettable, so re-watchable, and why none of the copies have ever approached its quality.
