Hungarian police Monday raided a warehouse of weapons to discover the guns were nothing more than props for a movie.

The mock weapons are realistic-looking machine guns, hand guns and rifles. They arrived at the Budapest airport aboard a private plane.

The prop guns are to be used in the upcoming horror film “World War Z,” directed by actor Brad Pitt.

But Hungarian authorities are not laughing. An anti-terrorism official says even transporting fake weapons is highly illegal in Hungary.
