Even before those infamous extensive reshoots, the production of "World War Z" was plagued by constant problems. Case in point: In October 2011, during filming, a warehouse holding weapons for the film was raided by a SWAT team. The weapons were largely assault rifles, with the issue here being that these were actually functional objects rather than the non-functional entities that paperwork suggested they were. Given that transportation of functional weapons like these was illegal, swift action involving law enforcement was taken, resulting in the SWAT team cracking down on a warehouse full of guns that were once planned for usage in "World War Z."
Despite such a massive show made out of securing the weapons, no legal processing would come about this matter. In February 2012, it was revealed that Hungarian authorities had failed to figure out who was responsible for all those guns. Unable to pin down a guilty party, charges over the matter were dropped. The whole thing generated some headlines for a few months thanks to a Brad Pitt movie getting embroiled in foreign legal trouble, but it mostly proved to be much ado about nothing. In hindsight, though, this entire event is just one of many instances where "World War Z" kept on generating the kinds of news headlines that studio executives have nightmares about.
