Continuity mistake: When Major Derval steps up to the co-pilots seat and sits down you can see him wearing an orange life preserver and strapping on the white four-point safety harness. However, when he removes the gamma gas from his pocket the safety harness is missing but is back in place in the next scene.
Continuity mistake: Near the end of the film as James Bond swims towards Palmeras, he gets out of the water to go up a flight of steps, and you see that he is wearing red shorts that are wet as he gets to the top. You then see a shot of Largo's henchmen getting into the back of a truck, as Bond goes down the next flight of steps the shorts are no longer wet, and they are now much lighter in colour.
Continuity mistake: After Bond had been dancing with Domino, Largo takes her to his jet boat to return to the Disco Volante for the night. Just when Largo asks her, "What was he saying just then?", in the background one can see Felix Leiter taking his sunglasses off and approaching Bond. Bond even turns his head towards him. The scene continues with Domino and Largo leaving in the jet boat. The scene cuts and the next shot shows Bond with Felix Leiter standing some steps behind him again, still wearing his sunglasses. (00:51:55)
Continuity mistake: James Bond is in the Shrublands clinic. He is snooping in a patients room. The patient (with bandaged face) opens the door. Bond hides behind the door and reaches into his jacket for his gun. A widescreen shot then shows his arm hanging down but in the next shot,his arm is back in the jacket. (00:13:05)
Continuity mistake: During the fight at the beginning of the film, you can see the fire in the fireplace burning brightly but when Bond is throttling his attacker with the poker, you now see that the fire (though partially hidden by the table) has nearly gone out, and does not burn as brightly. (00:03:10)
Continuity mistake: One for the wristwatch enthusiasts: Towards the end when Bond goes into the water he checks the time on his Omega. Later he looks at his watch and he's wearing the Breitling with built-in Geiger counter that Q gave him. Both shots are long and clear, probably because the watchmakers paid for them.
Continuity mistake: One of the gadgets which Q gives to Bond is a mini air tank, "good for about four minutes of air." He's very specific about this number. In the huge climactic underwater battle scene, Bond Against The Hordes, 007 puts on the mini tank and proceeds to fight, vigorously, for a solid ten minutes without borrowing anyone else's tank. He either had gills implanted or can fight while holding his breath for enormously long periods of time.
Continuity mistake: When Bond and Felix go out for the first time to search for the missing plane, Bond's hair has a parting to the left and is wearing watch on his left arm, but at the moment when they are flying over Largo's house, Bond is looking through a pair of binoculars. As he says to Felix "separate pools for sharks, no less" his hair is now parted on the right and his watch is now on his right arm, also watch out for the mouthpiece on Felix's headphones - it changes from left to right.
