Natalie Dormer has handled the twisted politics on Game of Thrones [1] and the life-or-death battles in Yes, this is a real thing [2].) In her new horror movie, The Forest, Dormer plays a woman whose twin sister disappears into the woods. Naturally, she goes after her — with the help of a strapping young guide (Taylor Kinney). The movie looks terrifying, and the fact that it was actually shot in the Aokigahara Forest makes it all the more chilling. It's out in theaters Jan. 8.
