The second collaboration between writer-director Zal Batmanglij and actress and co-writer Brit Marling is called The East, which happens to be the name of the movie's anti-corporate terrorist cult. Marling plays Sarah, an agent who infiltrates the group. She doesn't work for the FBI. Her employer is a private security and intelligence firm run by the sleek, profit-oriented Sharon, played by Patricia Clarkson. Its clients are Big Pharma, Big Oil, or Big Rich Any Corporation that, according to the group The East, poisons the world and everyone in it.
