8. World War Z
http://youtu.be/HcwTxRuq-uk I often find that the most intriguing trailers are the ones that dont even try to tell you whats going on. Is it a natural disaster? An alien invasion? This trailer pulled me right in from the start and I wanted to find out more. What the hell is causing so much chaos? The answer, of course, is zombies, but the trailer seems to go out of its way to avoid that word. What we see instead is basically a world gone to hell. These zombies arent localized, theyre not just after a small band of heroes, and they are millions of them. Which is what makes them so terrifying; sheer numbers is their main advantage. The final image of the zombies just piling up on one another to climb that wall pretty much says it all, and isnt one youll soon forget.
