Developed by Chad and Carey Hayes (The Conjuring) and overseen by that film's producer, Peter Safran, The Crucifixion has its roots in the true story of a priest who was convicted of murdering a nun after he performed an exorcism on her. Cookson will be playing a journalist investigating the case, trying to dig up the truth of whether he murdered an innocent, mentally unstable woman or if she was truly possessed by a demon. All involved will be hoping the new movie is as successful as The Conjuring, itself based on real events, which was a huge hit and spawned the prequel Annabelle (2014).
Cookson, who played Roxy in Kingsman, has already finished work on period adventure thriller Emperor alongside Adrien Brody (The Pianist) and Bill Skarsgård (Hemlock Grove). She is also attached to horror outing Hush, about a group of college students running a phony ghostbusting service who come up against some very real phantoms.
