Revealing mistake: When Bond notices the safe while looking at the mirror inside the liquor closet he turns around to look at the actual safe and the same shot seen in the mirror is used for Bond's point of view.
Factual error: When 007 is briefed inside the submarine, there would be no space available to have spacious offices, wooden desks, and book shelves. Most of the space within a sub would be taken up by the equipment necessary for it to function. In addition, such features (desks, chairs, etc.) would add a considerable amount of weight and be difficult to get inside in the sub in the first place.
Continuity mistake: The girl drives away from the wrestling arena sitting in the right seat, but when she drives up to the hotel she's sitting in the left seat. Either a flipped shot or a different vehicle.
Revealing mistake: When Bond stabs an assassin, we can see the spear going under his side.
Revealing mistake: When Bond exits the room after his meeting with M aboard the submarine, he slams the door, causing the whole wall to move.
Revealing mistake: When Helga traps Bond with a smoke-bomb and wooden restraint in the plane before jumping out to safety, you can see the wooden restraint has a pre-made crack down the centre when Bond eventually breaks loose.
Factual error: The room where Bond cracks the safe to steal some documents, there is a solid automatic door to enter the room. However right next to it, the wall is thin as paper (Japanese Shoji paper). It makes no sense to put a safe in a room like this or secure it with such a solid door when burglars just can walk through the walls. It's not armored milk glass or similar - during Bond's fight with the Japanese driver he already smashed one of these "walls" inside the room.
Revealing mistake: Every time Blofeld's rocket is shown approaching the American capsule near the end of the movie look closely at the screen. When we see the rocket on the closed-circuit screens you can tell it's a badly superimposed image because you can see the stars passing by behind it.
Other mistake: At the beginning of the movie James Bond is on a submarine underwater in Hong Kong harbor. Then, he is launched from a torpedo tube and is in Tokyo shortly afterwards. It's 1,800 miles from Hong Kong to Tokyo.
Suggested correction: Bond is on a submarine that has the capability of traveling from Hong Kong to Tokyo. Bond's meeting with M is even interrupted with an announcement that they're about to get underway. There's also a cut from Bond leaving M's office to Bond in a wetsuit preparing to exit the sub through the torpedo tube, a cut that could encompass the time period the sub took Bond into Japanese waters.
It takes several days for any submarine to travel one thousand eight hundred miles. There is no way, no how that submarine could have traveled 1,800 miles in a few hours. Not even the Disco Volante hydrofoil from Thunderball could have traveled 1,800 miles in a few hours, let alone a submarine traveling underwater.
Revealing mistake: When Bond back-drops Hans back into the water during their fight in Blofeld's quarters, you can see that Bond is not Sean Connery but his stunt double.
