Eventually, Ed and Lorraine Warren had to stop investigating supernatural activity. And, in the first trailer for The Conjuring: Last Ritesthe basic premise is that this case was so, so bad, it was the reason they stopped.
Now, how true that specifically is, we aren’t quite sure. But the trailer for the fourth and final Conjuring film starring Vera Farmiga and Patrick Wilson as the married investigators sure makes a compelling case. The plot isn’t quite on fully display but, from the casting, it sure seems as if the evil demons the Warrens fight on a daily basis have finally come for their own family.
In addition to Farmiga and Wilson, The Conjuring: Last Rites stars Mia Tomlinson as Ed and Lorraine’s daughter Judy Warren and Ben Hardy as her boyfriend, Tony Spera. And if the demons are coming after Ed and Lorraine’s kid, they are surely mighty pissed off about all the good they’ve been doing for humanity.
There are terrors throughout the trailer, but the scariest thing might be that this is being sold as the final Conjuring film centering on the Warrens. Because let’s not forget, it was the first two films in this series, The Conjuring and The Conjuring 2that set the series up to be the most successful horror franchise in a modern history. The Conjuring films also gave us Annabelle and The Nunboth of which had their own sequels and continue to be lasting brands on their own. And while the third Conjuring film, The Devil Made Me Do It, wasn’t quite as good as previous installments, you have to imagine everyone involved is going to go out with a bang this time around.
The Conjuring: Last Rites is directed by Michael Chaves, who did Conjuring 3 and Nun 2and once again produced by franchise architects James Wan and Peter Safran. It opens September 5. Here’s the poster.
