The director said when Garrett Hedlund dropped out three weeks before shooting began, he was given a list of six actors he could potentially choose from, three he dropped immediately. He went on to choose Alexander Skarsgård because of a YouTube video he saw of him drunk at a football match, in which he's trying to whip the rest of the crowd in a frenzy as he thought they were being too quiet. He thought this made him perfect for the role of Terry.
The quotation, "All oppression creates a state of war," is by Simone de Beauvoir, from The Second Sex (1949), her most famous work.
Filmed in Albuquerque, New Mexico.
When Terry is looking through Jackie's photos of ex-boyfriends, the first picture is that of Martin McDonagh, the brother of the film's director John Michael McDonagh.
