Fox Searchlight has released a new trailer for Sound of My Voice director Zal Batmanglij’s upcoming thriller The East.  The film stars Brit Marling as an undercover operative for an elite private intelligence firm who infiltrates a domestic terrorist organization in order to protect her corporate clientele.  Once she starts living as part of the anarchist collective, though, she finds that her loyalties aren’t as solid as she believed them to be.  I caught the film at Sundance and it’s a very solid thriller.  Batmanglij and star/co-writer Marling prove that they can skillfully craft a commercially pleasing film that still manages to be smart and thought provoking, and Marling turns in a riveting performance as the film's protagonist.  This trailer delves quite a bit deeper into the pic's plot than the first teaser trailer, and it gives you a good idea of the pic’s intensity level and story beats.
