Remember; no matter how desperate the situation seems, time spent thinking clearly is never time wasted.

There comes a point where emotions must give way to objective facts.

Gu was a worrier, a neurotic curmudgeon. If he had a headache, it was a brain tumor; if it looked like rain, this year's harvest was ruined. This was his way of controlling the situation, his lifelong strategy for always coming out ahead. Now, when reality looked more dire than any of his fatalisitic predictions, he had no choice but to turn tail and charge in the opposite direction.

When I started writing, there was nothing about zombies. It was all teen movies, which to me are scarier than zombies, but that's another story.

I think the general anxiety of the 1960s - '70s spawned our interest in the living dead. When people worry about the end of their world, they need a safe vessel for all their fears. Zombies provide that vessel because they're 'safe.

Secrecy is a vacuum and nothing fills a vacuum like paranoid speculation.

If I thought there was any hope of turning 'World War Z' into a movie, I wouldn't have written it as a giant, epic, global story, because that requires a giant, epic, global budget.
