VIDEO – ‘World War Z’ Official Movie Trailer WOW! Zombies, like we’ve never seen before! Cannot wait!When I first heard about World War Z I knew it was going to be something myself and my family would need to see. Now that the official movie trailer has been released, it’s confirmed. We LOVE zombie movies/shows, but this is like one we’ve never seen before.Entertainment Weekly interviewed visual effects supervisor John Nelson and here’s how he described this new batch of zombies:“They are like predatory animals that can’t control themselves. I worked with tigers [while shooting Gladiator], and if you watch them when a horse goes by they go batty, even if they know they can’t reach it. When Zs see humans they do same thing, they activate. They launch themselves. Everyone has seen everything in this genre. So of course we looked to try to find something new. And we have some.”He also revealed that the design teams used real-life predators for conceiving their new version of the pop culture zombie:“[Our zombies] move like birds or school of fish, too, in reactive formations, and it’s not because they have a higher level of [shared] thinking or communication – it’s about their nature and the fact that their instinct to infect is so basic, efficient, and overpowering. They will go through anything. If they lose both legs, they will walk on their hands. They lock in and they’re like salmon going upstream or sperm swimming to be the first to egg.”Check out the movie trailer for World War Z. The film, which stars Brad Pitt and is based on the Max Brooks book of the same title, is set to be released June 13, 2013.
