Count me in with the people who are skeptical about this translating to the silver screen. What, show the narrator beginning interviews and then go to a SNL “Diddly-doo” and wavy lines, then show the chapter? Focus on one story (probably the grunt in every battle from Yonkers to the end)? You’d miss so much of the impact and sense of global devastation.
I actually suspect that there will be a sequel of some kind. Max Brooks clearly has too much fun writing about zombies to quit now. There are a few things that could be filled in (Iceland, Israel, Australia, more of the sieges, Hawaii, most of Africa) but he’ll need to come up with more interesting bits to think about, like underwater zombies, cleanup of frozen zombies, quislings, and political secession. There’s a lot of room for other sieges to discuss, at least in my mind (what, like VMI and The Citadel are going to go without a fight?) but beyond that, he’s going to have to come up with more of the thought-provoking bits to have any success.
Brooks has a real fixation on Japanese martial arts prowess, too. One story, sure, but two? I enjoyed them but I also rolled my eyes a little.
As to zombie longevity mechanics- it’s not unbelievable that the body could consume itself for a long time, eating up unnecessary bits like a spleen, kidneys (they do say that zombie flesh tends to be toxic) and eventually excess muscle mass, but years? Nah. Days? Absolutely. Weeks? Probably. Months? Maybe. If they gained some kind of strength from eating, then sure. And we know that they eat any animals that they catch and flesh they can scavenge. But we also know that partial zombies that are missing their digestive tracts live for years. And while the body could consume itself for a while in theory, it would still need a circulatory system to get the raw materials it cannibalizes from itself to the muscles that need it. And of course, none of that could work underwater, because muscles need oxygen to move, which they couldn’t get. So basically, to my (limited) medical understanding, a zombie could consume itself for a long time, though probably not as long as Brooks assumes or under as unfriendly conditions.
They also talk about “draggers”, zombies that have lost their legs and drag themselves along with their hands. Sure, that would work for a while, but it would quickly grind the zombie to pieces, especially when on concrete or other rough surfaces.
