Natalie Dormer has landed another starring role!

The 32-year-old British actress, best known for his portrayal of Margaery Tyrell on the hit HBO fantasy drama series "Game of Thrones," is set to headline the supernatural thriller "The Forest."

Based on an original idea by David S. Goyer, the film is set in Aokigahara (also known as Suicide Forest) in Japan that lies at the northwest base of Mount Fuji where people go to end their lives. It follows a story of a young American woman named Sara (Dormer) who comes in search of her twin sister who has mysteriously disappeared, only to be confronted by the angry souls of the dead who prey on those who wander the forest, reported.

Jason Zada is set to direct the film from a script being re-written by Nick Antosca and Sarah Cornwell, according to Deadline.

During the Cannes Film Festival in May, Focus Features obtained the North American rights for the film and announced its plans to release it on Jan. 8, 2016. Good Universe has partnered with David Linde's Lava Bear to handle international sales on the film, Variety reported.

Goyer, Linde and Phantom Four's Nellie Reed are producing the flick.

Aside from "Game of Thrones," Dormer is also part of the cast of "The Hunger Games" franchise, in which she plays Cressida. "The Hunger Games: Mockingjay - Part 1" is due on Nov. 21, while the Part 2 is slated for a Nov. 20, 2015 release.

Just last month, it was announced that Dormer will also headline the upcoming Screen Gems action thriller film "Patient Zero," which will be directed by Stefan Ruzowitzky from a script written by Mike Le, reported.

"Patient Zero" centers on a worldwide pandemic that causes the evolution of a new species, according to Deadline. An aggressive form of rabies makes the infected humans into predators who are addicted to violence. But a miracle survivor with the unique ability to speak with the cannibalistic mutants using their language exploits his one of a kind gift to look for a cure to the plague.
