Actors Patrick Wilson and Vera Farmiga will reprise their roles as Ed and Lorraine Warren in The Conjuring spin-off, the untitled third Annabelle movie.

Wilson and Farmiga starred as the real-life paranormal investigators in 2013's The Conjuring which set the franchise in motion, and in The Conjuring 2.

The third instalment in the Annabelle series is also the sixth film in the Conjuring Universe.

The Nun, the most recent release, became the highest-grossing film in the franchise and it focused on the demon nun that came to life in The Conjuring 2 from a painting by Ed Warren and later attacked Lorraine Warren. Annabelle was introduced in The Conjuring as a demon doll in their artefacts room.

The story in the upcoming Annabelle film revolves on the doll awakening the room's evil, which sets its sights on a new target -- the Warrens' 10-year-old daughter, Judy, to be portrayed by Mckenna Grace. Madison Iseman has also been cast.

Gary Dauberman, who also wrote the script, will be making his directorial debut, and James Wan and Peter Safran will be bankrolling the film which will be released on July 3, 2019.
