We see the release of a new trailer for this summer’s epic zombie film based on the equally epic novel of the same name by Max Brooks.

World War Z is already the most expensive zombie film ever made with a budget rumored to be between 125-200 million dollars. Some of this has been due to the delays in filming and most of it seems to stem from a massive rewrite of the third act. Damon Lindelof was first hired to rewrite but due to prior commitments the job went to Drew Goddard. Such a rewrite also meant reshoots had to be done which took another seven weeks of shooting.

All in all, World War Z is one troubled film before it even gets to the general public.

Yet, it is also one of the more anticipated films for this summer. Some from fans of the genre who just can’t get enough of zombie films. Some from people wanting to see just what sort of zombie film ends up with a budget around 200 million dollars. From the trailer we’ve seen some of that money seem to have gone on some massive special effects sequences which includes swarming zombies of the Rage-infected kind. Then again we don’t really see the zombies close-up which tend to make them look like swarming ants from afar. Maybe the look of the zombies themselves have been saved for the release of the film.

This latest trailer actually gives a bit more of the plot of the film which puts Brad Pitt’s UN employee character to travel the world in search for the cause of the worldwide zombie pandemic. The speed by which things happen seems to have compressed all the events in the novel into a film of two hours. This, I’m sure will be a major contention with fans of the novel, but it looks like a decision by filmmaker to try and create a single narrative from a novel that was mostly single-hand accounts of the zombie war from survivors who have no connection with each other whatsoever.

We’ll find out in just under 3 months if this film will be a major flop or succeed despite all the stumbling blocks and problems throughout its production.

World War Z is set for a June 21, 2013 release date.
