WORLD WAR Z - Is this our first look at the zombies?

Could this be our first look at what the zombies will look like in Marc Forster's World War Z.  Some photos have arrived online that show what looks to be zombies were taken on the set in Philadelphia. 

For those of you hoping to see a movie that is the same as the book, you may not be too happy. The synopsis of the film will have Brad Pitt trying to stop the zombie pandemic instead of researching the oral history of the survivors.

Synopsis:

“The story revolves around United Nations employee Gerry Lane (Pitt), who traverses the world in a race against time to stop the Zombie pandemic that is toppling armies and governments and threatening to decimate humanity itself.  Enos plays Gerry’s wife Karen Lane; Kertesz is his comrade in arms, Segen.”

Head on over to AICN to see some other photos from the set. World War Z is set for release on December 21, 2012.
