We finally have some firm plot details for The Conjuring 3. Even though James Wan, who directed the first two installments of the franchise, won't be at the helm this time around, he's still heavily involved as a producer. Official details have been a bit scarce on the third installment, but Wan has been making the rounds promoting Aquaman, his latest directorial effort, and during a recent interview, he revealed that, once again, this movie will be based on the real-life case of files of Ed and Lorraine Warren. Here's what he had to say about it.

"It's not necessarily based on an artifact but it's based on one of the Warrens' case files. All the Conjuring films are based on the case files, so they're more based on the true story aspect of the real life Warrens. I think that's important. It's important that the mothership stays true to the inspiration of the real people. The spinoffs are where we get to have more fun and do weird and wonderful crazy things. The mothership of it being the Conjuring films, we want it to come back to the real stuff."

Over the last several years, the spin-offs within The Conjuring universe, such as the Annabelle franchise or this year's The Nun, have become quite successful. But they, unlike the "mothership" franchise, as James Wan Calls it, are not necessarily based on the Warrens' paranormal encounters. The Conjuring 3, as had been rumored previously, will specifically be dealing with a very strange murder case involving a man who claimed to be possessed at the time of the crime.

"It's this guy who was on trial for committing a murder. I think it's the first time in America's history where the defendant used possessions as a reason, as an excuse."

Undoubtedly, that's going to be quite a bit unlike what came before, as both previous Conjuring movies focused on more traditional tales of possession. As mentioned, James Wan won't be directing this time around. Instead, he's passing the baton to Michael Chaves, who worked with Wan on next year's The Curse of La Llorona. Wan also says that Chaves impressed him, which is what landed him the gig.

"I feel like he's this young up and coming filmmaker in this world. He's a guy that understands how these films work. He's really great working with actors and I feel like that's something I want and need to work with, someone that people like Patrick and Vera would feel comfortable with."

Both Patrick Wilson and Vera Farmiga will return as Ed and Lorraine Warren in The Conjuring 3. But first, they're going to appear in Annabelle 3, which recently wrapped production and is set to be released next summer. The Conjuring 3 does not yet have a release date, but it's expected that Warner Bros. is going to get the ball rolling so that it can arrive in 2020. We'll be sure to keep you posted as any further details on the project are made available. This news was first reported by Bloody Disgusting.
