Claim: The House of Exorcism was produced by Alfredo Leone.
Evidence: Alfredo Leone After the popularity of the film The Exorcist, scenes were added by producer Alfredo Leone and Lamberto Bava which gave the film an exorcism theme and re-released it as The House of Exorcism (Italian: La casa dell'esorcismo) in the United States; this recasts the film as a clone of The Exorcist, with the main character possessed and recounting to the priest who is seeking to save her the story of how she became possessed.
