If you’re a horror fan, you know The Conjuring series, including its sequel and its spinoff franchise, Annabelle. But did you know that before its release, The Conjuring was almost titled The Warren Files? It’s true; director James Wan liked the name because of its reference to the film’s heroes, paranormal investigators Ed and Lorraine Warren. Eventually the title was changed, however, to The Conjuring. That’s just one of the frightening facts featured in the latest installment of You Think You Know Movies!

Ed and Lorraine Warren are real-life ghost hunters; another one of their cases inspired the film The Amityville Horror. Development of The Conjuring took many years; for a long time writers tried making the film primarily from the perspective of the Perrons, the family that lived in the movie’s haunted house. It was only after a new set of writers decided to shift focus to the Warrens that the project took off, inspiring a bidding war among numerous studios before the film ultimately landed at New Line Cinema.
