While based on the novel, Straczynski’s script stands alone as a classic in the zombie genre. Indeed, with the right cast and direction, World War Z could stand as one of the strongest dramas in the last decade. In a way, JMS added a new element to Max Brooks’ initial vision of a global zombie war. With The Zombie Survival Guide, World War Z, and the Straczynski script; Max Brooks’ tale is finally complete.
Personally, I'd shoot this as a sort of Citizen Kane of zombies, with a narrator essentially going around and setting up a series of flashbacks that tell the story of the horrible events of the Z-War, and it looks like Straczynski's doing exactly that. Personally, after Children of Men, I'm pushing for Alfonso Cuaron to direct this, but I'm certainly open to seeing any talented director's take on the material.
