America is especially sensitive to war weariness, and nothing brings backlash like the perception of defeat. I say “perception” because America is a very all-or-nothing society… We like to know, and for everyone else to know, that our victory wasn’t uncontested, it was positively devastating.

Lies are neither bad nor good. Like a fire they can either keep you warm or burn you to death, depending on how they're used.

That's the thing about zombies. They don't adapt and they don't think. Literally, you could have a zombie on one side of a chain link fence and you could be on the other side and they could be trying to get to you and six feet down could be an open door and they will not go through that door in the fence. That's why they're so scary.

They didn't break me. I broke myself.

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 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.
