Are people that died before the outbreak able to reanimate? Or do you have to be living to catch the disease that everyone has? I'm just wondering what might be going down at the cemeteries.
We have no onscreen evidence that the already dead reanimate. But I always thought it was unlikely in the zombie flicks that portray the fact that they do that the zombie could crawl out of a coffin and up 6 feet of dirt. Besides they seem to be motivated on a need to feed and nothing in a coffin would agitate them.
