Other mistake: When James Bond is in Tanaka's underground train enjoying the sake wine. One servant enters saying that the photograph is ready for viewing. This servant then walks to the door, which is on the left-hand side of the carriage. After going through the door, we can see the servant taking a left turn, but where to? Outside the moving train?
Other mistake: When Bond arrives on the island with the fake volcano, Kissy tells him that nothing unusual has happened there, except the death of a diving girl when she ventured into a cave. Even if the construction of the launch facility in the volcano had been kept secret it would have been impossible to launch the large rocket twice without anybody noticing.
Other mistake: Early in the movie, in the shot of the police vehicle screeching to a halt in front of the hotel Bond is staying at you can see a crowd of people huddled together on the sidewalk with a policeman making sure they stay put. (The producers had to order the area in front of the hotel closed off to civilians as a precaution as so no one would get hurt or get in the way of the filming).
Other mistake: The first few ninjas enter the volcano on ropes thrown down when 007 partially opens the crater roof. After the roof is closed, all their ropes should be collected to the right side of the screen after the roof is shut. But the ropes are not gathered to the right side. Similarly, ninjas next enter the crater through the hole blown in the crater roof. But in scenes following the crater explosion, you see ninjas descending into the crater on ropes tided to the under pinning of the crater roof instead of ropes coming through the blown out roof hole. Also, the blown out crater roof hole s not visible in the subsequent scenes.
