(CBS) The set of Brad Pitt's upcoming film "World War Z" was raided on Monday - but not by eager fans or paparazzi.
A SWAT team raided a Budapest warehouse holding weapons being used while filming the zombie movie, Us Weekly reports.
According to the magazine, officials seized 85 fully-functional weapons, the majority of which were automatic, military-style assault rifles.
The issue, reportedly, was that the accompanying paperwork for the weapons claimed they didn't work, which isn't the case.
Hajdu Janos and Zsolt Bodnar, the director and deputy director of Hungary's Anti-Terrorism Unit, told Us Weekly: "Guns like these are highly illegal to transport even if they were to used as stage guns, which hopefully they weren't."
Pitt, 47, is reportedly not pleased with the mix-up.
"The film is already over budget and over schedule," a source told the magazine. "Brad is furious."
Before filming in Budapest, "World War Z" was shooting in Glasgow, Scotland. The movie is scheduled to hit theaters in December 2012.
