The troubles behind World War Z have never been secret, but they’ve definitely been tackled lightly by mainstream press. That ends today as Vulture is reporting that star Brad Pitt and director Marc Forster have broken up.

“The horde of zombies in Paramount Pictures’ World War Z aren’t the only ones ravenous for brains: So is the troubled blockbuster’s star and producer, Brad Pitt, who Vulture hears exclusively from multiple production sources has become so frustrated with the film’s director, Marc Forster, that he stopped speaking to him altogether as the production heads into at least three weeks of reshoots,” says the website. “Things got so bad that when Forster had notes on a scene for Pitt, they had to be relayed through an intermediary — and vice versa.”

They also note the irony of the situation adding that “Pitt, whose company, Plan B, is producing World War Z, originally fought for Forster to be given the director’s chair on World War Z. The studio was wary, because his only other big-budget action film was Quantum of Solace, the 2008 James Bond film that proved a notoriously difficult shoot.”

And while previous reports hit that both Damon Lindelof and Drew Goddard have reworked the finale, the site claims that Paramount is still trying to decide whether to just try to fix what they have or get writers to completely re-envision the film’s final. The shocker (I guess?) is that whatever happens with the script, additional — and possibly outside — directing help is likely to be sought for the action sequences that will need to be reshot.

The adaptation revolves around United Nations employee Gerry Lane (Pitt), who traverses the world in a race against time to stop the Zombie pandemic that is toppling armies and governments and threatening to decimate humanity itself.
