Yesterday, we got a very frightened Emma Watson on the first Regression poster. Today, TWC-Dimension has released the pulse-pounding trailer for this taut thriller on Emma Watson's Facebook, which will push you over the edge. Director Alejandro Amenábar, best known for classic shockers The Others and The Sea Inside, returns for yet another spooky tale. And genre favorite Ethan Hawke is coming along for the ride.

Set in Minnesota in 1990, Regression follows detective Bruce Kenner (Ethan Hawke). He's sent to investigate the case of young Angela ( Emma Watson), who accuses her father, John Gray (David Dencik), of an unspeakable crime. When John unexpectedly and without recollection admits guilt, renowned psychologist Dr. Raines (David Thewlis) is brought in to help him relive his memories and what they discover unmasks a horrifying nationwide mystery.

Regression also features Aaron Ashmore, Devon Bostick, Dale Dickey and Lothaire Bluteau. The creative team includes production designer Carol Spier, director of photography Daniel Aranyó, costume designer Sonia Grande, casting directors Jina Jay and VFX supervisor Felix Bergés. Based on Alejandro Amenábar's original screenplay, Regression will be released in theaters on August 28.
