When official trailers were released, the International Association of Exorcists branded The Pope’s Exorcist: “unreliable … splatter cinema”.
The film’s protagonist, Father Gabriele Amorth (Russell Crowe), is based on a real Catholic exorcist who was a founding member of the very organisation condemning the movie as inaccurate. So cinema-goers had fair warning that it would be far from uncontentious.
