Since the 1973 movie, The Exorcist, there has been one exorcist movie after the next. There are six installments in the Exorcist franchise. The latest is The Exorcist: Believer in 2023. One exorcist movie, The Exorcism of Emily Rose, produced by a Biola University graduate is based on the true exorcist tragedy of 24-year-old Anneliese Michel. Two Catholic priests performed 67 exorcism sessions, one or two each week, lasting up to four hours, over ten months in 1975–1976. Anneliese Michel died the next year and her parents and the two priests were found guilty of negligent homicide.
