During the work in Japan, hundreds of reporters appeared on the set and started firing away with their cameras so much that the noise was distracting, so the producers hired 30 private security guards to drive them away. On the second day, the guards themselves started taking pictures for the reporters. Some of them shot star Sean Connery while sitting on a toilet and the picture was published in a Tokyo newspaper.
Reportedly, the noise made during the shooting of the film's grand finale on the volcano set scared Blofeld's white cat and it ran away. It took several days to find the cat and it was eventually discovered hiding in some of the set's rafters. The cat is not seen with Blofeld in many scenes because of this, but footage of the scared cat wound up in the finished movie very briefly when Blofeld's security shutters are enforced.
The movie had a number of firsts: First time the screenplay was not based on the original Ian Flemming novel. Only the Tokyo setting from the book matched what was on the screen. First time Bond is seen in his Navy uniform. First time Bond actually meets Blofeld. (From Encore channel's weekend with Bond, February 2009.)
