The labyrinth of limestone caves seen in the film stretch some twenty-three miles underneath a brewery in Buda, Hungary. They were originally excavated as quarries in the 1700s, and later re-purposed for beer storage. At various times they have been used as emergency shelters and even hidden hangars for Nazi aircraft. When the film was being shot, while the temperature above ground was mild, at the subterranean depth of the caves, breath condenses in the air, and crew-members donned winter hats and jackets for this reason.
