Very mild spoilers ahead from The Curse of La Llorona.
The Curse of La Llorona recently screened at South by Southwest, confirming how the movie connects to the Conjuring universe. The movie is set in Los Angeles in 1973, and has the connective tissue of Father Perez (Tony Amendola), who returns to the story from Annabelle. In this film, Father Perez talks to Anna Garcia (Linda Cardellini) about his evil doll case, and the doll is flashed on screen to further drive home the connection (per Bloody Disgusting).
The 2014 Annabelle movie was also set in Southern California, with the story in 1967. The Conjuring, which came out in 2013, was set in 1971. The Conjuring 2 was set in 1976 and 1977. So The Curse of La Llorona appears to fit into the timeline between between the first two Conjuring movies, just a few years after Father Perez's experience in Annabelle.
Since The Curse of La Llorona just screened, critics and fans have been sharing their early thoughts online. CinemaBlend's own Sean O'Connell felt the film compared poorly to previous Conjuring movies, although he had fond words for Linda Cardellini:
Perri Nemiroff of Collider also had some measured praise, calling it a solid start for future Conjuring 3 director Michael Chaves:
Erik Davis of Fandango had a much simpler warning about the movie -- it may leave you afraid to visit your own attic:
The Curse of La Llorona was produced by James Wan, who directed the first two Conjuring films before passing the reins to Michael Chaves for the upcoming third movie. This is the sixth film in The Conjuring Universe after The Conjuring, Annabelle, The Conjuring 2, Annabelle: Creation, and The Nun. It precedes Annabelle 3, aka Annabelle Comes Home, which just announced its title and June 28, 2019 release date. The Conjuring 3 is reportedly scheduled for September 11, 2020. The Crooked Man should be following them at some point, but there's no set date right now.
The Curse of La Llorona opens in theaters on April 19, yep one week before Avengers: Endgame. Pray for it. The horror movie is just one of the many films releasing in theaters in 2019.
