Phil Hay and Matt Manfredi, frequent collaborators of filmmaker Karyn Kusama (Aeon Flux, Destroyer), are writing the script.

The project posits the question: What if the horrors imagined by H.P. Lovecraft, the troubled author of At the Mountains of Madness and the short story The Call of Cthulhu, were not imaginary but real? The script is set in the 1920s, and get ready for tentacled monsters.

Lovecraft was a Vertigo graphic novel whose rights were optioned by Warners around three years ago. The project has been quietly gestating since then. Rodionoff is a comics and television writer who now works at Adam F. Goldberg Productions.

Benioff and Weiss are currently seeing the cast of their acclaimed HBO show Game of Thrones receive acting nominations from SAG and other organizations during the current awards season. The pair were also working on a Star Wars trilogy, which recently got shelved.
