This volume closely examines the near-ubiquitous images of state security walls, domes, and other such defense enclosures flashing across movie screens since 2006, the year of the ratification of George W. Bush's Secure Fence Act. This study shows that many of the films of this era enable us to imaginatively test the effects of these security mechanisms on citizens, immigrants, refugees, and other sovereign states, challenging our commitment to constructing them, maintaining them, staffing them, and subsidizing their enormous overheads. With case studies ranging from Atomic Blonde and Ready Player One to Black Panther and Elysium; Walls without Cinema serves as a timely counterpoint to the xenophobic rhetoric and abusive, carceral security conditions that characterize the Trump administration's management of the Mexico-U.S. border situation.
