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 your Soviet neighbor is trying to set fire to your house, you can't be worrying about the Arab down the block. If suddenly it's the Arab in your backyard , you can't be worrying about the People's Republic of China and if one day the ChiComs show up at your front door with an eviction notice in one hand and a Molotov cocktail in the other, then the last thing you're going do is look over his shoulder for a walking corpse.

We relinquished our freedom that day, and we were more than happy to see it go. From that moment on we lived in true freedom, the freedom to point to someone else and say “They told me to do it! It’s their fault, not mine.” The freedom, God help us, to say “I was only following orders.”-World War Z

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

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.

The dead walk among us.

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.
