Corrected entry: In the scene with the Portuguese gunsmith, the gunsmith says that the rifle is designed for the pressure of three fingers, and that's why Bond hits an inch too low. Well, maybe at the distance to the target disc, but not on all distances. Right at the nozzle you wouldn't hit an inch too low, and at further distances you'd hit lower. So when Bond shoots at the gunsmith's groin, he wouldn't hit an inch too low, since the guy is standing much closer than the target at the firing range.
Corrected entry: At the beginning of the film the gangster screws a silencer on his gun, but when he fires the sound effect is for an unsilenced gun. (00:03:00)
Corrected entry: During the car chase Bond makes a wrong turn and ends up at the wrong side of the river. He corrects his mistake by using a collapsed bridge to jump across the river. A few shots later you see that three police cars following Bond made the same mistake. However, they arrive only a few seconds after Bond at the place where Scaramanga is changing his car into an airplane. It's very unlikely that they all jumped across the river.
Corrected entry: Near the beginning of the film, the "gangster" character is shown entering Scaramanga's lounge to wait for him. He racks the slide on his pistol, and then turns out the lights. When Scaramanga enters the darkened room a few moments later, the gangster racks the slide again, alerting Scaramanga to his presence (and presumably ejecting the first cartridge he had already chambered - a ridiculous waste of ammo).
Corrected entry: When Bond is taken to the karate class, one of the "students" is performing a kata, which is a sort of a "karate dance". In a kata one starts and finishes at the exact same place, but the one in the film starts the kata at the center of the platform, and finishes it the the right end of it. (00:52:05)
Corrected entry: When Bond and Lt. Hip are in the car, and find out the Goodnight has the car keys, they try to quickly acquire another car; leading to Bond stealing one from the AMC Dealership show room floor. Are we to believe that a highly trained and resourceful secret agent like James Bond can not do a simple thing like "jump starting" the first car's ignition?
Corrected entry: In the scene where Scaramanga invites Bond for lunch, at the dinner table Scaramanga tells Bond he would like to with duel with him, Bond asks Scaramanga "My six shots to your one?" referring to his own Walther PPK and Scaramanga's Golden Gun. The Walther PPK can hold up to fifteen rounds per magazine, plus one in the breech, and he has not used any rounds before that shot in the same scene, so there should be fifteen/sixteen rounds in the magazine.
Corrected entry: In the shot where J.W. Pepper and his wife get off their tour boat, the wife wants to buy one of the carved miniature elephants. J.W. says "Those are damn Democrats". In actuality, the elephant represents the Republicans; the donkey is the Democrat.
