Though I've never read the book on which the film is based, I am familiar with its unique format (a compilation of individual
accounts comprised a decade after the
war), and while it may not please fans of the source material, the decision to streamline all the
action through Gerry makes the story flow better.
The works of Max Brooks, who wrote 2003's satirical and subversively political, «The Zombie Survival Guide», and 2006's, «World
War Z: An Oral History of the Zombie
War», provided the kernels of inspiration for this mega-budgeted horror -
action - thriller that mostly makes up its own narrative, independent of much of the book content (jettisoning the first - person
account style and most of the events), to make it fit more with the ranks of current, eye - candy loaded popcorn movies than a thoughtful adaptation of the best - seller.
