Something tells me that by the time World War Z opens in June, all of the stories last year about the colossal production problems and rancor on the set will be, if not forgotten, then at least rendered moot: Who wants to think about inside baseball stuff when fast-moving zombies are laying waste to the world’s capitols?

And I did say “fast moving.” These zombies race so fast, it’s hard to believe they have time to eat anyone. When the first trailer for World War Z came out, I wasn’t sure what I was watching – the zombies swoosh across the screen like a tidal wave of death.

Now the movie has a new trailer (you can watch the trailer below). Brad Pitt, playing a U.N. official, leaves his wife and children behind to race around the globe in search of a cure. We’ve seen some of the footage before, but this trailer lays the situation out a little differently. And it ends with something I don’t think I’ve seen before, or even thought about: How do you battle zombies on a plane?

I haven’t read Max Brook’s book, on which the movie is based, but watching this trailer I am struck by how little World War Z seems to resemble traditional horror movies. These don’t seem so much like monsters that you fight but a faceless phenomenon that you flee, a condition that you try like hell to protect yourself from or an epidemic that you try to find the cause of so that you can stamp it out.

I suspect we’ll see real-life parallels in the plot – Hurricane Katrina, the AIDS epidemic perhaps…maybe even geopolitical conflicts – though it remains to be seen how hard the movie will bear down on this. After all, this was to be an awards-season release, with reports circulating that Pitt (who also is a producer) viewed the film as the first of a trilogy that would use the zombie genre to examine geopolitical issues. But that was before Damon Lindelof, best known as the writer behind TV’s Lost, was brought in to retool the film, and the movie was pushed back.

Now World War Z is a summer movie. And there are zombies on that plane.

Where is Samuel L. Jackson when you need him?
