Watch: Game of Thrones' Natalie Dormer has a scary shower scene in The Forest trailer

Natalie Dormer loves taking on a juicy action-filled role. From the twisted family politics of Game of Thrones to the harrowing battles of The Hunger Games: Mockingjay, she's no stranger to life or death situations…but this is definitely her scariest role yet.

The trailer, which launched on MTV, finds Margaery Tyrell a long way from Kings Landing and in the forests of Japan, searching for her lost twin sister. In one chilling scene, she takes a shower and we can't help but think of Psycho – watch above!

Joined by Lady Gaga's fiancé Taylor Kinney, she must navigate the treacherous Aokigahara Forest, a real-life suicide hotspot associated with demons in Japanese mythology.
