The new film from EXORCISM OF EMILY ROSE director Scott Derrickson sees star Ethan Hawke investigate the dark past of his new house, and these first looks have him in the throes of observation. 

SINISTER sees "a true crime novelist (Hawke) struggling to find his next big story, moves his family into a house where the horrific murder of an entire family took place. But after finding a box of home videos in which other families are also brutally murdered, his investigation leads him to a supernatural entity that may be placing his own family in harm’s way."

SINISTER is out August 24 from Summit.
