On a smaller scale, "World War Z" also appeals to the world of preppers – people who prepare for mass chaos brought on by the breakdown of social institutions. (A Washington D.C. press screening of the "World War Z" even featured a panel of preppers to answer questions before the film). As Gerry rushes around a war zone of a grocery store grabbing all the food, supplies and medicine he could, the viewer can't help but to think, Maybe I should pick up some extra batteries on the way home – or an AR-15.
"I think this is mind candy for preppers" Bourne says, adding that preppers usually have more realistic situations in mind, like natural disasters. "If you can prepare for a zombie apocalypse you, are prepared for everything else," he says.
While people write off preppers, it's hard to deny how under-prepared our institutions are to deal with a zombie takeover, or even a lesser crisis.
"One of the things I was thinking as I was watching 'World War Z' is just how easy something like that would totally break down our society. People would be in chaos," Weiner says. "The most enduring stories use the zombie to highlight us in the foreground."
