ups of a Roman  galley, a Chinese junk, etc. Bond would rouse the allies into action  with a spoof of Lord Nelsons famous cry, "Las Vegas expects every  man to do his duty." Alas, Maibaum was misinformed; there were no  Roman galleys or Chinese junks in Las Vegas, and the idea was too  expensive to replicate, so it was dropped. Maibaum may have thought  the eventual oil rig finale a poor substitute, but it was originally  intended to be much more spectacular. Armed frogmen would jump from  the helicopters into the sea and attach limpet mines to the rigs  legs (this explains why frogmen appear on the movies poster).  Blofeld would have escaped in his BathoSub and Bond would have  pursued him hanging from a weather balloon. The chase would have  then continued across a salt mine with the two mortal enemies  scrambling over the pure white hills of salt before Blofeld would  fall to his death in a salt granulator. Permission was not granted  by the owners of the salt mine, and it also made the sequence too  long. Further problems followed when the explosives set up for the  finale were set off too early; fortunately, a handful of cameras  were ready and able to capture the footage.
