World War Z, the forthcoming zombie apocalypse movie starring Brad Pitt has experienced a brief hitch in production after a Swat team raided the movie's warehouse in Budapest, Hungary. Authorities seized 85 fully-functional weapons, including military-assault rifles, reports US Weekly Magazine.

Hadju Janos and Zsolt Bodnar, the director and deputy director of Hungary's Anti-Terrorism Unit, confirmed the raid, saying the weapons were brought into the country under the pretence they were non-functional. A statement read, "This morning a private plane brought guns wrapped in a parcel from a company to an individual in Budapest.Guns like these are highly illegal to transport even if they were to used as stage guns, which hopefully they weren't". The seizing of the weapons is yet another obstacle for a high profile movie already over budget and behind schedule. Pitt, who plays U.N journalist Gerry Lane, is said to be "furious" with the Swat team. An investigation seeking to determine how the weapons were allowed into the country is now underway, with director Janos noting, "We are interrogating witnesses now, getting closer to solving the firearms story".

World War Z, based on Max Brooks novel 'World War Z: An Oral History of the Zombie War' is slated to hit cinemas on 21st December 2012. Filming has already taken place in Malta, Cornwall and Glasgow.
