To me, the zombies have always just been zombies. They've always been a cigar. When I first made Night of the Living Dead, it got analyzed and overanalyzed way out of proportion. The zombies were written about as if they represented Nixon’s Silent Majority or whatever. But I never thought about it that way. My stories are about humans and how they react, or fail to react, or react stupidly. I’m pointing the finger at us, not at the zombies. I try to respect and sympathize with the zombies as much as possible.
