Max Brooks’ two recent, brilliantly conveyed novels (The Zombie Survival Guide, World War Z: An Oral History of the Zombie War) have intellectualized the debate surrounding zombie mythology to a staggering degree. My friend Eddie is a man bearing a strong allegiance to the stoic credibility of Brooks, a zombie purist, if you will, and he balked when he saw the zombies toting machine guns in Umberto Lenzi’s Nightmare City. It seemed as obnoxiously antithetical as the image of a cow sitting in a chaise lounge, sipping a martini. Zombies don’t carry guns. That’s just silly.
