Continuity mistake: During the chase scene when several men in boats are chasing Bond in a boat, one of the bad guys steals a black speedboat from the Sheriff's brother-in-law. The bottom of the black speedboat collects white scuff marks as the chase continues, but the scuffs increase and decrease erratically, indicating that the sequences were not shot in the order we see in the film.
Continuity mistake: After Bond is picked up by the taxi at the airport in New York, Whisper in the "white pimpmobile", as Felix Leiter puts it, shoots the taxi driver in the head. The car then swerves from the second-left lane on the road to the very left lane. But in the next shot of Bond's head you can see through the rear window that there is a car on the left side of the taxi, indicating that the car is still in the second-left lane. In the next shot the taxi is back in the very left lane.
Continuity mistake: In the opening, in some shots the snake is straight whilst in others it is curled back in and under itself.
Continuity mistake: After Bond has killed the snake with the aerosol can in his hotel bathroom, he puts down the cigar he is smoking next to the sink. When he hears the door opening, he walks into the bedroom and the cigar is back in his mouth again.
Continuity mistake: When the first British MI6 agent (Dawes) is killed by killer waves sent through his earphones at the United Nations, he has his fingers closed when the waves go through, but the next shot shows him with his fingers wide apart.
Continuity mistake: When Tee Hee is about to bend the barrel of Bond's Walther PPK, he has his index finger on the trigger guard of the gun, but the next shot shows him holding the gun with all his fingers around the handle.
