It should be common knowledge which aspects are important for the zombie subgenre and most of the zombie films are celebrating these with pleasure.
Getting such an excellent box office result was of course only possible because of the PG-13 rating in movie theaters which was considered a banana skin by some people. That’s a large number, so it’s not surprising that a sequel is being discussed.
He came up with a completely different ending. The studio decided to spend 20 more million on the movie and hire Prometheus writer Damon Lindelof. It’s all very sinister and not so typical for a big budget Hollywood production. He’s taking down walkers with the Russian army in a huge battle scene. Here, we see Pitt’s character a few months later after previous events. Especially the third act (after the Jerusalem sequence) taking place in Moscow was troubling them. But when the people in charge at the studio saw the first rough cut, they got scared. The shooting of the movie with production costs of 190 million USD under supervision of German director Marc Forster ( James Bond – Quantum of Solace) was finished pretty fast. And people had even more concern about the Brad Pitt zombie flick World War Z. Didn’t hurt the movie, though, and critics were basically satisfied, as well. Lots of rumors about alterations and reshoots were caused by it. The prognosis for Men in Black 3 became worse and worse when the fact that the shooting had begun before the screenplay was actually finished was made public. It looks like especially blockbusters are under heavy surveillance. But sometimes, a reshoot causes fear regarding the quality of the movie. Sometimes, it’s the director, sometimes the studio. After shooting the actual movie, a reshoot is often required because scenes are missing or because they’re not entirely satisfying.
That a movie production doesn’t always go smoothly is daily routine for the industry.
