World War Z Trailer Now Officially Online

It's finally here. After teaser trailers, teaser posters, and teaser images, the World War Z full trailer has been officially released online via Apple iTunes Movie Trailers. World War Z is based on a book written by Max Brooks. It features Brad Pitt taking on what looks to be an army of zombies.  Unlike The Walking Dead where the zombies move slow allowing for plenty of time to load a crossbow and shoot them with an arrow, the World War Z zombies move fast. These zombies are like a force of nature, attacking in huge waves. World War Z was originally scheduled to be released later this year, but the release date was pushed back. World War Z is now officially slated to be released in theaters on June 21, 2013, even though the World War Z teaser poster only says 2013.
