Transforming George R.R. Martin's "A Song of Ice and Fire" fantasy novels into one of HBO's biggest and most successful shows should have set David Benioff and D.B. Weiss up for life, and I suppose it has in a way, but given the reaction to the final season, I'd imagine that many will be approaching the pair's future projects with caution.
Deadline has reported that David Benioff and D.B. Weiss are developing an untitled H.P. Lovecraft thriller at Warner Bros. which has been inspired by the graphic novel by Hans Rodionoff, Todd Klein, and Enrique Breccia. There doesn't seem to be many details about the project just yet, but Deadline has heard that the film revolves around the horrifying question: "What is H.P. Lovecraft wasn't making it up? What if the monsters he created are real?" It's also been said that the film will take place in 1029 within the Cthulhu mythos. The script is set to be penned by Phil Hay & Matt Manfredi, the team behind Karyn Kusama's THE INVITATION and DESTROYER, who is also onboard as an executive producer. Deadline added that Benioff and Weiss have been eyeing this project for several years, but were too involved in Game of Thrones to do anything about it at the time.
A synopsis of "Lovecraft" via Amazon:
A fascinating but disturbing study of one of America's greatest horror writers, the intense LOVECRAFT examines the bizarre life of author and recluse, Howard Phillips Lovecraft. Since his early childhood in the late 1800's Lovecraft was haunted with dark visions of demons and death. Trapped in a world of macabre creatures and grotesque thoughts, the writer found escape only by weaving his living nightmares into fictional blood curling horror stories. An uncensored tour into a troubled mind, this beautifully painted hardcover edition traces the toils of a man considered both mentally ill and genius as he stumbles across the fine line between reality and insanity.
David Benioff and D.B. Weiss are still able to move forward with the H.P. Lovecraft project at Warner Bros. as the discussions for the project predate their megadeal with Netflix.
