A few months after The Conjuring became a box office hit in the summer of 2013, New Line Cinema went ahead with the horror spinoff Annabelle, which offered an origin story for the creepy doll featured in the first movie. Now that The Conjuring 2 opened big with $40.3 million at the box office, the studio is developing yet another spinoff, entitled The Nun. Ironically, this Nun character was actually a last-minute addition to The Conjuring 2. If you haven't seen The Conjuring 2 yet, there will be SPOILERS below, so read on at your own risk.

The Hollywood Reporter reveals that this demon nun character was added into the film just months before the movie opened, during reshoots. James Wan had a cut of the movie where the villain was simply a demon with large horns, who Ed (Patrick Wilson) and Lorraine Warren (Vera Farmiga) encounter. The studio was ready to release this version, but then the director had a last-minute vision that this character was actually a demonic nun. He convinced the studio to undergo reshoots in March, three months before the movie opened on June 10.

While some of the changes that needed to be made were minor, with the art piece Ed Warren is painting being changed from a demon to a nun, others were much more extensive. One scene that was added involved Lorraine Warren watching the nun's shadow crawl across a wall to line up with the painting. Bonnie Aarons portrayed the nun in The Conjuring 2, but we'll have to wait and see if she comes back. The Nun was also featured in an epic prank video that surfaced just before the sequel's release in Brazil.

David Leslie Johnson, who wrote The Conjuring 2, has come aboard to write this spinoff, with James Wan and Peter Safran coming back to produce. No director is in place yet, but it seems unlikely that James Wan will return to the helm, since he will take on Warner Bros.' Aquaman, which is set for release in the summer of 2018. New Line hasn't set a release date for The Nun quite yet, and it isn't known if the studio will also move forward with The Conjuring 3 or not. James Wan recently teased that the sequel could be about werewolves, but nothing is set in stone quite yet.

The Conjuring 2 has already grossed over $100 million worldwide from a $40 million budget over its opening weekend. The sequel's predecessor, The Conjuring, opened with $41.8 million, en route to $137.4 million domestic and $318 million worldwide, from a $20 million budget. The 2014 spinoff, Annabelle was also a hit with audiences, earning $84.2 million domestic and $256.8 million worldwide, from just a $6.5 million budget.
