Man of Steel came out a little over a month ago and has earned $620 million across the globe. We still don't know for sure if it's getting a sequel. The Conjuring hasn't hit theaters yet, hasn't earned a single dime, and the sequel is already in active development. Funny how quickly some films become franchises. (And yes, obviously the massive cost of making a Superman movie has something to do with it.)
Directed by James Wan and written by Chad and Carey Hayes, The Conjuring tells the story of real-life ghost hunters Lorraine and Ed Warren (played by Patrick Wilson and Vera Farmiga) as they attempt to get to the bottom of what's going on in a house the Perron family just moved in to. However, any sequels to the film will then abandon the Perron family's abode and follow the further investigations of the Warrens. And that's a great idea. Most horror franchises stick with one location or one killer; sticking with the Warrens frees up any sequels to go to all kinds of different places and explore different hauntings, which hopefully means they'll stay fresher past the point a lot of franchises go stale.
The real Warrens checked out countless hauntings in their time as professional ghostbusters, including the stories behind The Amityville Horror and The Haunting in Connecticut. One of those will most likely serve as the setting for The Conjuring 2, as it is directly referenced in Wan's movie, though we won't say which one considering the movie isn't even in theaters yet. As for Wan, he's unlikely to return to direct the sequel (he's already moved on to Fast & Furious 7), though the Hayes brothers are returning and have apparently already "interviewed Lorraine Warren extensively as part of developing the script."
As for The Conjuring, sequel or not, we do implore horror fans to check it out this weekend. Having already seen it, we feel very, very safe in saying it's one of the most solid haunted-house movies to come out of Hollywood in quite some time.
