An entertaining (if you can label a supernatural horror film that) directed by Julius Avery from a screenplay by Michael Petroni and Evan Spiliotopoulos, based on the 1990 book An Exorcist Tells His Story and the 1992 book An Exorcist: More Stories by Father Gabriele Amorth.
About Father Amorth
Gabriele Amorth S.S.P. (Italian: [ɡabriˈɛːle ˈaːmort]; May 1, 1925 – September 16, 2016) was an Italian Catholic priest of the Paulines and an exorcist for the Diocese of Rome. Amorth and five other priests founded the International Association of Exorcists.
His work in demonology and exorcism gained him international recognition. Father Amorth claimed to have performed tens of thousands of exorcisms, at least 60,000 throughout his career. He became one of the most prominent and controversial figures in the Catholic Church in the modern era.
Amorth was born in Modena, Emilia-Romagna, Italy, on May 1, 1925. He was ordained a Roman Catholic priest in 1954 and was appointed an exorcist of the Diocese of Rome in June 1986 under the tutelage of Candido Amantini. He was a member of the Society of St. Paul, the congregation founded by Giacomo Alberione in 1914. In 1990, he founded the International Association of Exorcists and was president until his retirement in 2000.
Both Father Amorth’s father and grandfather were lawyers. His contributions during World War II as a courageous fighter for the Italian resistance movement were followed by his pursuit of legal studies. Additionally, Father Amorth served as a deputy to Giulio Andreotti, a prominent figure in Italian politics who would later become Prime Minister within the influential political organization of the Young Christian Democrats.
Amorth died at the age of 91 on September 16, 2016, a short time after he was hospitalized for pulmonary complications.
