L'esorcista - La genesi

Morgan Creek Productions fired Paul Schrader after he had submitted a completed movie, saying that he had given them "footage without any of the bloody violence the backers had wanted". He had already made it clear in interviews that he was making more of a psychological drama than an all-out gore-fest. He was fired and Renny Harlin was hired to re-shoot the movie. Almost 90% of the movie was re-shot, re-casting several roles and adding and removing characters. Following the lackluster reception to Harlin's version, though, Schrader's version was finally released as Dominion: Prequel to the Exorcist (2005).

(at around 1h 19 mins) Father Gionetti gives Father Merrin a copy of the Rituale Romanum (Roman Ritual). (The administration of exorcism is in Title X of the Rituale Romanum.) The title of the book embossed on its leather cover is "Roman Ritual", in English. Later in the film (at around 1h 35 mins), Father Merrin asks Joseph to help him by reading passages of the book, and we are shown a couple of printed pages, the text of which is also in English. The Rituale Romanum would have been printed in Latin in 1949, when the film is set, because vulgar translations of liturgical texts were not authorized until the promulgation of the Sacrosanctum Concilium (Constitution on the Sacred Liturgy) by Pope Paul VI on 4 December 1963, as part of the Second Vatican Council.
