I found this video online completely by accident. It's some raw footage of a scene in what seems to be NY from the "upcoming" World War Z. It appears that the zombies are coming and soldiers are rushing into action as civilians flee. This footage is from 2011 so there's not guarantee that it will even be in the final movie. What is interesting is that no zombies are in the scenes. Let's hope that doesn't mean excessive use of CGI. Check it out below:
