Siblings Andy and Barbara Muschietti, director and producer of Guillermo del Toro’s Mama, will produce the next project of Alex and David Pastor, supernatural thriller In Shadows, reports Variety.

Spanish writers-directors, the Pastors, also siblings, were behind both The Last Days and Carriers, pictured above.

The Pastors’ In Shadows turns on Jason, a man who comes out of prison after serving 20 years for an unspeakable crime, and is forced to confront the terrible events of his past that sent him there.

“In Shadows is a twisted coming-of-age story, a dark tale where supernatural horror is a manifestation of the most mundane horror the characters face in their daily lives. Unfolding along two different timelines, the movie explores how the horrors of the past can haunt us all our lives and define us as adults,” David Pastor explained to the site.

“In a similar way to features such as Near Dark or Let the Right One In that gave the genre a spin, a twist, In Shadows will do the same,” said Andy Muschietti.

“We wrote the kind of genre movie that as audience members we long to see: a character-driven horror film that is as scary as it is emotional, a supernatural tale that uses its fantastical elements to explore the darkest impulses of its characters,” Alex Pastor added.

The screenplay has been penned by Alex and David Pastor.

It is scheduled to go into principal production in the first quarter of 2016.
