Revealing mistake: When the ninjas enter the volcano one of them slices a SPECTRE man in the back with a sword, however there is no mark.
Other mistake: During the shooting scene in the false volcano: We see a man on a bridge being shot and he falls on the rail and down. About a minute later, they show the same shot.
Continuity mistake: Two of the helicopter pilots who are killed by Bond in the "Little Nellie" aerial dogfight are the same ones, only without sunglasses, who later in the film are patrolling the coastline near the volcano and who try to kill Kissy Suzuki.
Revealing mistake: When Blofeld destroys the volcano lair, as the camera is showing a view of the volcano, you can see the pressure waves move the bodies on the floor and tell that they are obviously dummies.
Continuity mistake: When Bond first stands on top of the volcano, when it opens, it is dark outside. The camera then shows it opening from inside the volcano, outside it is daylight.
Revealing mistake: When the rocket lands in the Volcano lair, you can see the thread used to lower it; a crane hook is even visible at the top of the screen.
Continuity mistake: In the scene where Bond is being made to look Japanese, prior to posing as a local fisherman his chest is being prepared for shaving - 'couldn't you just dye the bits that show?' he quips. In the last scene his chest is back to its full, furry glory.
Continuity mistake: When Bond is flying Little Nellie during the attack by the SPECTRE helicopters, he uses all of his armaments. Afterward, however, when Bond is told to proceed to a certain position, the Nellie is seen pulling away fully armed.
Revealing mistake: While Bond is taking his "civilized" bath with his Japanese counterpart and four ladies, there are two shots where you can see James wearing skin-colored swim trunks.
Revealing mistake: The gunman sitting in the back of the black sedan who shot at Bond coming out of the Osato building is not the same guy sitting when the sedan is picked up by the helicopter Tanaka sent to help Bond and Aki.
Continuity mistake: When Bird 1 is about to intercept the first space craft it slows down without firing any brake rockets.
Continuity 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.
Audio problem: During the scene where Bond has to make his way back into the control room, he asks Tiger Tanaka to cover for him. Tiger does so with an MP-40 submachine gun. It's the loudest gun on screen when Tiger is firing it and has the MP-40's distinctive clatter. So far, so good. However, watch the gun's muzzle flashes (the MP-38, MP-38/40, and MP-40 as well as the MP-41 all have cyclic rates slow enough to distinguish between individual shots). When Tiger fires the first burst out of the gun, it corresponds perfectly well with the muzzle flashes. However, after cutting to Bond and then back again to Tiger, something went wrong. The muzzle flashes don't correspond at all to the firing noises from this point onward. In fact, when Tanaka takes his finger off the trigger momentarily to presumably prevent muzzle climb or let the barrel cool for an instant, the firing noises keep going.
Continuity mistake: As the SPECTRE helicopters begin to attack little Nellie, Bond's helmet microphone switches from his right side to his left and back again.
Factual error: The picture of Ning-Po taken by the American tourist is nowhere near sharp enough - or high enough resolution - for it to be enlarged sufficiently for the ship's name to be legible.
Continuity mistake: When Bond is trapped in the light airplane flown by Osato'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.
Other mistake: During the Little Nellie helicopter battle scene, the same footage of enemy copters being destroyed is used three times.
Continuity mistake: The first time we see the fake lake retracting in the volcano it is moving very fast, and before the cut it is almost totally retracted. But in the next clip when seen from below the opening is only half of the crater and the roof is retracting much slower.
Plot hole: The American spacecraft is said to be scheduled for launch at midnight Japanese time. But from the place in the movie where it is shown it is late afternoon or early evening.
