Robert Kirkman has also given a small update on the show.

"They start filming episode four in a few days," said Kirkman. "So they’re trucking along and all I can really say is that everyone has been a dream to work with. Frank [Darabont] is doing amazing work, Gale [Anne Hurd] is just awesome at what she does and AMC has been a real treat to work with. This show is something unlike anything that’s ever been on television before. I think people are just going to flip out when they see what we’ve done here.

"It was a pretty cool experience, I got the chance to work in an actual writer’s room with series writers Chic Eglee, Jack LoGiudice and Adam Fierro and it’s been a real treat getting to learn the process and see how it all works. I also got direct guidance from Frank Darabont himself, which is really just priceless. He’s such a talented screenwriter, his advice should be written on stone tablets and have religions based on it."

"AMC is such an amazing network," continued Kirkman. "They’ve had two major successes in 'Mad Men' and 'Breaking Bad' and they’ve expanded at a very slow, deliberate rate . . . it’s pretty unusual. I was thrilled they were interested in 'The Walking Dead,' and now that I know a lot of the other things they’re developing for other new shows, I think the network is just going to continue to get better and better. I couldn’t be happier to be a part of their network."
