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.
