Brad Pitt 'not speaking to World War Z director Marc Forster'

Brad Pitt is allegedly not speaking to his World War Z director Marc Forster.

The Moneyball actor is so "frustrated" with Forster that he has stopped talking to the director altogether as the film heads into three weeks of reshoots, reports Vulture.

Paramount's production president Marc Evans and film group head Adam Goodman along with Dede Gardner, who runs Pitt's production company Plan B, are apparently acting as intermediaries, relaying messages between Pitt and Forster, such as director notes.

According to the report, the film was working under a tight deadline and without a finalised script when it started shooting last summer.

The release date had to be pushed back until June 2013 after Paramount executives and Pitt were not happy with some of the big action set pieces, especially the film's ending.

World War Z was planned for! a Chris tmas 2012 release.

A source told Vulture: "The studio is cultivating multiple options. One is to try scrapping [the ending] and trying something different: They want to construct an entirely new ending to the movie.

"The other is to try salvaging it, because decent action can be elevated, and even s**tty action can be saved. This is not an unmitigated disaster; it is salvageable."

Back in June, the studio hired Prometheus writer Damon Lindelof to make rewrites on parts of World War Z.

However, the World War Z script "needed months of work" and "changes were needed throughout the film, not just at the end", another source claimed to Vulture.

Pitt, whose company is producing the movie, has final approval over the new pages written by the writers.

World War Z is based on Max Brooks's book of the same name, starring Pitt as a UN employee who travels around the world to stop the outbreak of a Zombie pandemic.
