Jacob Elordi (Saltburn) and Lily-Rose Depp (Nosferatu) are set to star in “dark fairytale” Outer Dark, a film based on Cormac McCarthy’s 1968 novel.

It is set in Appalachia during the Great Depression and tells of a young woman who bears her brother’s baby. The brother leaves the nameless infant in the woods to die but tells his sister that the newborn died of natural causes and had to be buried. The sister discovers this lie and sets out to find the baby for herself. But as both brother and sister separately move through the countryside, three terrifying strangers are on their tails, wreaking death and destruction wherever they appear.

Laszlo Nemes (Son Of Saul) directs from a script Nemes wrote with Clara Royer.

Mike Goodridge of London-based Good Chaos is producing alongside Nemes; executive producers are Ilene Feldman, Ori Eisen of Original Films and Nicolas Gonda. Good Chaos and Nemes have the book-to-screen rights.

Deadline first reported on the development.
