It's Brad Pitt against a world full of zombies in director Marc Forster's thriller World War Z, which will be available for purchase on Digital Download September 10 before debuting on Blu-ray, Blu-ray 3D and DVD September 17. We have an exclusive featurette that explores the hive mentality of these zombies. Visual effects supervisor Scott Farrar and science writer Carl Zimmer explain how this aspect is taken from certain animals in nature, such as ants or termites, who work together to scale walls in a similar way that the undead manage to breach a wall in this action-thriller. Go behind-the-scenes to see early renderings of these pivotal sequences, and check out the special features details below.

Starring international superstar Brad Pitt and based on the best-selling and wildly popular novel, World War Z took audiences by storm and was hailed by critics as "thrilling, epic and spectacular" (Owen Gleiberman, Entertainment Weekly) and the "most gratifying action spectacle in years!" (David Denby, The New Yorker). The tense and thrilling film follows a former United Nations investigator (Pitt) as he helps stop the chaotic pandemic that has gripped populations around the world. World War Z features stunning visual effects and edge-of-your-seat action and suspense that take the Zombie apocalypse phenomenon to a more extreme and electrifying level.
