In The Conjuring, we were introduced to paranormal investigators Ed and Lorraine Warren. One of their real-life cases served as the basis for James Wan's terrifying drama, set in 1971. Since then, we've experienced a series of scary stories in Annabelle, The Conjuring 2 and Annabelle: Creation, going back and forth in time as more real-life cases have been dramatized.

The next installment in the series, The Nun, will soon arrive in theaters. In our exclusive video, James Wan explains how it fits into The Conjuring universe.
