Game of Thrones star Emilia Clarke is starring in the upcoming horror film from director James Ashcroft, When Darkness Loves Us. Bleecker Street has acquired the project from The Rule of Jenny Pen‘s filmmaker and has set a 2027 cinema release date.

Also starring in the pic are Marlon Williams (Sweet Tooth), Victoria Pedretti (You, The Haunting of Hill House), and Natascha McElhone (The Truman Show).

When Darkness Loves Us follows a young woman (Clarke) who, after surviving fifteen years trapped in an underground cave system, returns to the surface to reclaim the family she believes to be hers, no matter the cost.

The script is co-written by Ashcroft, Hayley Sproull, and Eli Kent, and is based on Elizabeth Engstrom’s 1985 horror novella of the same name.

“My passion for Elizabeth Engstrom’s story remains boundless; what an absolute gift it has been bringing this work to the screen,” said Ashcroft. “With When Darkness Loves Us, Liz never lets us forget that the actions of her characters are by turns both tragic and monstrous — no matter how sympathetic they may be. But it’s their indelible humanity that can’t be so easily shaken off afterwards, and that’s when we find ourselves at home in the darkness with them.”

“The term ‘world-building’ is wildly overused, but the degree to which James and team have built a subterranean universe cannot be understated,” said Bleecker CEO Kent Sanderson. “This film is a true journey into the darkness, literally and figuratively, and we can’t wait to shock audiences worldwide with James’ singular vision.”
