Hope will play Sister Victoria, a nun haunted by a demonic presence.

Corin Hardy is directing the project, which was written by Gary Dauberman and Wan. Wan and Peter Safran are producing.

Production begins this week in Romania with a planned release date of July 13, 2018.

The Nun is the second title to spin off from the Conjuring universe, with Annabelle being the first. A sequel to the latter, Annabelle: Creation, is set to open Aug. 11.

Hope played Myranda, the sadistic servant and lover of Ramsey Bolton, over the course of several seasons of Game of Thrones. She also appeared in the British biographical romantic drama A United Kingdom and the Brad Pitt thriller Allied. The actress will next be seen in The Three Christs of Ypsilanti opposite Richard Gere.

Hope is repped by CAA and Mosaic in the U.S. and The Artists Partnership in the U.K.
