Downton Abbey star Dan Stevens plays muderous war veteran in horror-thriller The Guest

Picturehouse has revealed the official U.S. trailer for the hybrid horror/thriller The Guest, top lined by Downton Abbey Star Dan Stevens. Adam Wingard, the director of You’re Next, helms The Guest, which features what’s being described as a standout, badass performance from Downton Abbey’s Dan Stevens. The tense, action-packed and unpredictable film is like everything and nothing you’ve ever seen before.

Downton Abbey’s Dan Stevens plays a soldier who introduces himself to the Peterson family, claiming to be a friend of their son who died in action. After the young man is welcomed into their home, a series of accidental deaths seem to be connected to his presence.

The film was written by Simon Barrett and also stars Maika Monroe, Leland Orser, Sheila Kelley, Brendan Meyer and Lance Reddick.

The Guest visits movie theaters starting on September 17, 2014. Check out the new trailer from Picturehouse, below.
