However, The Conjuring chose a different case to adapt: the haunting of the Perron family in Harrisville, Rhode Island, in 1971.

While these spin-offs vary wildly in quality (from the masterful Annabelle: Creation to the disappointing The Nun ), they all owe their existence to the slow-burn dread of the original. Furthermore, The Conjuring 2 (2016) successfully moved the scares to London’s Enfield Poltergeist case, proving the formula was repeatable, while The Conjuring: The Devil Made Me Do It (2021) pivoted to a courtroom drama, showing the franchise's versatility.

In the pantheon of modern horror, few franchises have cast a shadow as long—or as profitable—as The Conjuring . What began as a singular film in 2013 has spiraled into a multi-billion dollar universe, spinning off demons, nuns, and crooked men into their own blockbusters. Yet, at the heart of the screaming audiences and jump scares lies a surprisingly simple, character-driven core: the true story of Ed and Lorraine Warren.
