One of the first promotional trailers for “Regression” was released earlier today. The new thriller, starring Ethan Hawke and Emma Watson, will release later this summer but you can get an early look at the film thanks to the trailer below.

In the film a father is accused of a gruesome crime, which he has no memory of committing. While investigating the crime, and the surrounding players, a detective uncovers more than he could have possibly imagined.

The film reunites Emma Watson and David Thewlis, who many Harry Potter fans will remember played the role of lovable Professor Lupin in the franchise. “Regression” was directed and written by Alejandro Amenábar, who also directed Nicole Kidman, Christopher Eccleston and Fionnula Flanagan in the horror-thriller “The Others”.

Horror-fans won’t have to wait too long before “Regression” hits their local theater, the film is scheduled to premiere on August 28, 2015.
