Authorities in Hungary raided the set of Brad Pitt’s zombie movie World War Z today and seized a cache of weapons, People reports. The police took possession of 85 weapons that were being stored in a Budapest warehouse, including AK-47s and sniper rifles that authorities say were equipped with live ammunition and had not been rendered fully inoperable, creating what they maintained was a potentially deadly safety hazard. A publicist for the film, which is slated to hit theaters next year, said that the production was working with the police to resolve the matter.
