What if the monsters of H.P. Lovecraft’s tales were real? That’s the premise behind an untitled film that’s set up at Warner Bros., Deadline reports this week.

Inspired by Hans Rodionoff’s graphic novel Lovecraft, the project comes from “Game of Thrones” creators David Benioff and D.B. Weiss.

The site details, “I’m told the movie asks a horrifying question: what if H.P. Lovecraft wasn’t making it up? What if the monsters he created are real? Also, the movie will be set in 1920 within the Cthulhu mythos.”

Phil Hay and Matt Manfredi (The Invitation) are writing the script, with Karyn Kusama (Jennifer’s Body, The Invitation) executive producing.
