Though the film might not be the greatest horror film of all time nor the best example of a legendary Brad Pitt performance (though it is a horror film better than it has any right to be and Pitt never phones it in), “World War Z” is still a film that gets brought up every so often as a lost opportunity. You see, for years now, a sequel to the film has been in development with none other than David Fincher attached to direct and Pitt returning.
