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.
