World War Z is a 2013 American disaster zombie film directed by Marc Forster. The screenplay by Matthew Michael Carnahan, Drew Goddard, and Damon Lindelof is from a screen story by Carnahan and J. Michael Straczynski, based on the 2006 novel of the same name by Max Brooks. The film stars Brad Pitt as Gerry Lane, a former United Nations investigator who must travel the world to find a way to stop a zombie pandemic.

Pitt's Plan B Entertainment secured the film rights in 2007, and Forster was approached to direct. In 2009, Carnahan was hired to rewrite the script. Filming began in July 2011 in Malta, on an estimated $125 million budget, before moving to Glasgow in August 2011 and Budapest in October 2011. Originally set for a December 2012 release, the production suffered some setbacks. In June 2012, the film's release date was pushed back, and the crew returned to Budapest for seven weeks of additional shooting. Damon Lindelof was hired to rewrite the third act, but did not have time to finish the script, and Drew Goddard was hired to rewrite it. The reshoots took place between September and October 2012.

World War Z premiered in London on June 2, 2013 and was chosen to open the 35th Moscow International Film Festival. The film was released on June 21, 2013, in the United States, in 2D and RealD 3D. The film received positive reviews and was a commercial success, grossing over $540 million against a production budget of $190 million. A sequel was announced shortly after the film's release.
