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

They say great times make great men. I don't buy it. I saw a lot of weakness, a lot of filth. People who should have risen to the challenge and either couldn't or wouldn't. Greed, fear, stupidity and hate. I saw it before the war, I see it today. [...] I don't know if great times make great men, but I know they can kill them.

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.

During the Qin Dynasty, all books not relating to practical concerns such as agriculture or construction were ordered burned by the emperor to guard against "dangerous thought." Whether accounts of zombie attacks perished in the flames will never be known. This obscure section of a medical manuscript, preserved in the wall of an executed Chinese scholar, might be proof of such attacks.

Zombies let us explore notions of the apocalypse - no water, food, medical care, the government imploding - while letting us sleep at night.

I think 'G.I. Joe' is a perfect example of how I'm the world's worst businessman. If I were smart, I'd be writing 'World War Z Part 12', but I have to go where the muse leads, and I've always been a huge 'G.I. Joe' fan. I always wanted to know more about these characters, these little plastic figures I played with as a kid.

If I knew anything about what people wanted and was popular, I'd still be writing for 'Saturday Night Live'. I can only write what I want, and hopefully people will like it.
