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.

Zombie books were going to be my passion projects, but certainly not pay the bills. I thought I was going to have to get a real job on a sitcom or something, and have my zombie books to remind myself I was still a writer at heart. I never thought I could actually pay my bills and write what I wanted.

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.

The bottom line is I'm a slow zombie guy - I'm always a slow zombie guy but I also know I'm in the minority.

You can watch 'Dawn of the Dead' and still sleep at night. Try that with 'The Day After'.

I think that most people would rather face the light of a real enemy than the darkness of their imagined fears.

After all we'd been through, we still couldn't take our heads from out of our asses or our hands from around each other's throats.
