a subversive film that critiques 1960s American society, international Cold War politics, and domestic racism. Elliot Stein of The Village Voice saw the film as an ardent critique of American involvement in the Vietnam War, arguing that it "was not set in Transylvania, but Pennsylvania – this was Middle America at war, and the zombie carnage seemed a grotesque echo of the conflict then raging in Vietnam." Film historian Sumiko Higashi concurs, arguing that Night of the Living Dead was a film about the horrors of the Vietnam era. While she admits that "there are no Vietnamese in Night of the Living Dead, ... they constitute an absent presence whose significance can be understood if narrative is construed". She points to aspects of the Vietnam War paralleled in the film: grainy black-and-white newsreels, search and destroy operations, helicopters, and graphic carnage. In the 2009 documentary film Nightmares in Red, White and Blue, the zombies in the film are compared to the "silent majority" of the U.S. in the late 1960s. While George Romero denied he considered race when casting Duane Jones, reviewer Mark Deming notes that "the grim fate of Duane Jones, the sole heroic figure and only African-American, had added resonance with the assassinations of Martin Luther King Jr. and Malcolm X fresh in the minds of most Americans". Stein adds, "In this first-ever subversive horror movie, the resourceful black hero survives the zombies only to be surprised by a redneck posse". The deaths of Ben, Barbra, and the supporting cast offered audiences an uncomfortable, nihilistic glimpse unusual for the genre. Other prevalent themes included "the flaws inherent in the media, local and federal government agencies, and the entire mechanism of civil defense". Film historian Linda Badley explains that the film was so horrifying because the monsters were not creatures from outer space or some exotic environment, "They're us." Romero confessed that the film was designed to reflect the tensions of the time: "It was 1968, man. Everybody had a 'message'. The anger and attitude and all that's there is just because it was the Sixties. We lived at the farmhouse, so we were always into raps about the implication and the meaning, so some of that crept in."
