What's it about? A group of strangers find themselves holed up in a farmhouse after the dead begin to come back to life and attack the living. We all know the drill by now - as the zombies (refered to in Night of the Living Dead as "ghouls") increase in numbers the survivors become increasingly desperate and start turning on one another in their desperation to come out on top.What makes it groundbreaking? Zombies had featured in movies before but never had they been depicted as the lumbering, rotting monsters featured in George Romero's Night of the Living Dead. Romero pushed on-screen gore in entirely new directions, shocking audiences more than any previous horror B-movie had ever hoped to, while the undercurrent of political commentary and observations about racism in America retain their potency today.
