The Rite is a 2011 supernatural horror film directed by Mikael Håfström and written by Michael Petroni. It is loosely based on Matt Baglio's book The Rite: The Making of a Modern Exorcist, which itself is based on actual events as witnessed and recounted by American then-exorcist-in-training Father Gary Thomas and his experiences of being sent to Rome to be trained and work daily with veteran clergy of the practice.
