 The Zamberlan article also refers to the inappropriate use of galvanized metric hexagonal bolts, and poor quality workmanship.In the 1979 James Bond film "Moonraker", Bond battles a bad guy in Venice and ends up throwing him through the face of the clock, which is made of glass in the film, and down into a piano in St Mark's square below, disrupting an opera performance.The real clock was not used, and in fact its face consists of revolving metal disks and its mechanism is quite different from that seen behind it in the movie.
