As the poster tells you this is the cinematic version World War Z starring Brad Pitt. First off, this would have been better off have been named something else since the novel it’s borrowing its name from is a collections of individual accounts about the cataclysmic event.
This, along with some shoddy looking CGI, looks like a run of the mill Hollywood production with Pitt out to save the world against super fast extra climby zombie ant people.
