Director Martin McDonagh discusses his new film, Three Billboards Outside Ebbing, Missouri, with fellow Director Niki Caro. The film stars Frances McDormand as Mildred Hayes, a woman frustrated by the fact that months after her daughter's violent murder, no progress has been made in the case. Infuriated by the lackluster effort by the local police, she commissions three billboards leading into her town with messages aimed at Ebbing's revered chief of police thereby setting off a battle of wills with the police force and the local community.
