Continuity mistake: In the scene where Bond is trapped in the light airplane flown by Osata's female pilot, she sets the airplane on fire and bails out. As she's exiting the plane, its landing gear is down. Once Bond frees himself and tries to recover the airplane, the landing gear is back up.
Deliberate mistake: When 11 is dropped into the water and eaten by the piranhas, although the ravenous fish probably ate most of her and what was on her, there should at least be pieces of clothing that would rise to the surface in the flurry of activity. Not to mention that even though the water is a murky green all the blood from her body should have created a temporary, but very noticeable darkening of the water.Tobin OReilly
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: 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.
