Bonnie Aarons joins 'Conjuring' spin-off as the demon sister

Actress Bonnie Aarons is set to reprise her role as the demonic sister for the "Conjuring 2" spin-off titled "The Nun".
Demian Bichir and Taissa Farmiga are starring in the movie to be directed by Corin Hardy, reported Variety.
Bechir will portray a priest and Farmiga will play the titular nun.
The studio started developing "The Nun" last June, shortly after the release of "The Conjuring 2".
The project will be produced by James Wan, who directed the two "Conjuring" movies and produced the sequel, and Peter Safran, who produced both movies.
Written by Gary Dauberman and Wan, "The Nun" centers on Bichir's character travelling to Rome to investigate the killing of a nun.

The demon nun, a manifestation of the evil spirit Valak, became part of the story in "The Conjuring 2".
