Revealing mistake: When the submarine surfaces with the life raft on the casing at the end of the film, the water movement looks a bit odd because the scene was actually shot with the sub diving and floating the raft off, the film then being played backwards.
Plot hole: The ferocious battle in the crater ends instantly when Bond blows up the space ship. Why? Aren't Blofeld's men still going to try to defend themselves? How do they know Bond has succeeded in his mission? They can't see the control room, let alone the television sets.
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.
Continuity mistake: In the scene at the end where Bond is trying to make Blofeld's spaceship blow up, you can see the timer showing the time till interception. On the 1st shot the timer shows 25 seconds. On the second shot it says 13 seconds. Then there is another shot and the timer shows 24 seconds.
Plot hole: At the end, we see pictures of the space shuttle several times on a TV screen. Where is the camera to film that?
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.
Continuity mistake: When Aki drives James to see Tiger and when she collects him from Osato Chemicals, her car changes from left hand to right hand drive as the camera follows them along.
Factual error: In the scene where the ninjas are attacking the volcano, they are armed with rocket guns. While the rocket guns, MBA Gyrojet Rocket Carbines, are real, their 13mm rocket cartridges could barely beat out a .45 ACP pistol cartridge in stopping power, not to mention they couldn't cause huge explosions like they did in the movie.
Continuity mistake: When Bond and Kissy jump into the ocean to avoid the poison gas in the cave, you can see Bond's skin through his shirt. When they come ashore on Blofeld's volcano island, Bond takes off his shirt to reveal a grey ninja outfit underneath, complete with huge rubber suction cups for his hands and knees. Where did he hide all that?
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.
Factual error: Two rocket lift-offs are shown. For the American lift-off, they show an Atlas-Agena (American) rocket booster but for the Soviet lift-off, they show a Gemini-Titan (also American) rocket booster.
Continuity mistake: While Bond prepares "Little Nellie" for flight, a Japanese technician removes the red rotor tether from the front of the Autogyro. In the next shot, while Bond is putting his flying helmet on, the tether is still attached to the rotor.
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 pick up by the helicopter Tanaka sent to help Bond and Aki.
Plot hole: Right after Bond escapes Blofeld and joins Tanaka and Kissy, they say they need to get to the Control Room (that Bond just left from), they look at the "front door" to the Control Room and Tanaka says "Impossible! It's too well defended!". Why did they not go back the way Bond just came from, through Blofeld's "apartment"? Instead, they fight their way across the entire launching complex and go through another entrance, which ALSO leads through Blofeld's "apartment".
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?
Continuity mistake: When Blofeld is just about to shoot Bond with a Webley & Scott Mk. IV revolver in .455 Webley caliber, Blofeld's hand is hit with a ninja throwing star. However, the gun he drops isn't the Webley, but a Smith & Wesson .38 Special.
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.
Plot hole: In the volcano base, Bond finds and frees three captured astronauts - two Russians and an American. But when they enter the SPECTRE astronauts' room, there are only two of them with Bond (and there is no indication that the third one was seriously hurt in the previous struggle with the guards); and after Bond is dressed in the spacesuit, they disappear from the story altogether.
