Audio problem: When Bond and Honey are on the beach the hoods of Dr No come by boat. On the boat there is a guy shouting through a megaphone. As they sail away again the man waves the megaphone to his comrades and says "full speed ahead". Yet his voice sounds identical to when he was speaking through the megaphone, though he isn't holding it to his mouth anymore. (01:04:00)
Audio problem: When the powerboat shoots at the island, afterward, when the guy with the speakerphone tells them that he would be back later on, he then turns to the driver and tells him to move on, but when he says that, it sounds as though he's still talking in the microphone even thought the microphone is at his side.
Audio problem: When Bond goes in to see M, you can see Bond speaking just after he sits down. His lips move quite a lot, but there is no sound. (00:10:45)
Audio problem: When the radio controller in London says "Hello, W6N. Report my signals", his lips don't move.
