Watch Natalie Dormer Leave Westeros Behind In First Trailer For ‘The Forest’

As Margaery Tyrell on Game of Thrones, Natalie Dormer is no stranger to the horrors that lurk around the darkest of corners. But not even the two-headed monster of King Joffrey and Cersei could prepare Dormer for the ghosts and ghouls that await her in The Forest. In the upcoming supernatural thriller, Dormer plays a woman whose search for her missing twin sister takes her to Aokigahara, the real-life Japanese forest notorious for its frequent suicides. It's also said to be haunted, and if the first trailer for The Forest is any indication, it definitely, definitely is. The Forest hits theaters January 8, 2016.
