Continuity mistake: One of Bond's traps in his room is his briefcase; he puts talcum powder on it. When he is done he sets the case down on the right side of the table. To the left is a mirror and by the mirror is an assortment of perfume bottles and a shaving bag. When he returns, the contents on the table are reversed exactly, and the perfume bottles are replaced by a magazine. (00:24:25 - 00:40:20)
Continuity mistake: When Bond leaves the hotel to go to Governor's House he has no pocket square. At Governor's House he has his pocket square. Then in the next scene at professor Dent's, the pocket square is gone again. (00:25:30)
Continuity mistake: When Bond goes to see a fisherman, to ask him about a man's death, the fisherman walks away, saying he knows nothing, and walks into a bar on the beach. He is talking to the barman and the bar has nothing on it, until a second later, when, suddenly, there is an open bottle of beer, a glass half-filled with beer and an ashtray. (00:28:00)
Continuity mistake: When we first see Bond and Quarell talking in the bar, Quarell asks if Bond likes good eating, to which Bond replies he does. Camera cuts and his entire facial expression has changed from smiling and laughing to a deadpan serious one. (00:28:30)
Continuity mistake: During the evening meeting in the bar, we can see the band and a singer, but the movement of his lips (despite the fact that they were trying to hide them behind a big microphone) doesn't match what is sung. (00:30:15)
Continuity mistake: When the freelance photographer is sitting down with Bond, the strap is around her neck, after the cut to a close up of her, the strap is gone. Then they show Bond take the strap off her neck. (00:31:35)
Continuity mistake: When Quarrel gets cut by the broken flash bulb, he has a lot of blood on his face and the rag. The next scene he's fine with no blood. (00:32:45)
Continuity mistake: When Dent walks into the room to be questioned by Dr. No we don't see the table with the spider cage in the first side shot but Dent only walks a few feet from the chair, and suddenly there's a table. (00:38:00)
Continuity mistake: When the spider crawls up Bond's arm, and we see the spider in close-up, they are using a stand-in with much more muscular arms than Sean Connery. (00:42:00)
Continuity mistake: When Bond gets directions to Miss Taro's house, her instructions to Bond conclude with "Follow the road up the hill, down the other side, and two miles further on, on the left Magenta Drive, 2391," but when Bond is in her house later on, while calling for a taxi, the house number changes and he gives it as "2171 Magenta Drive". Miss Taro even nods to confirm it. (00:47:30 - 00:51:20)
Continuity mistake: During the car chase, on the way to Miss Taro's house, we can see the same shot of the cars at the turn three times. (00:48:15)
Continuity mistake: During the car scene, the black car rams into Bond. Then the camera cuts and the black car is about 5 feet behind Bond without any time to have slowed down. (00:48:45)
Continuity mistake: The hearse that was involved in Strangways' death and later chases Bond is a 1937 or 1938 LaSalle, with the pod-style headlights mounted on stalks on either side of the radiator. The car that drives off the cliff and explodes is a later model car, with the headlights mounted flush into the fenders. It is very easy to spot while the burning car is rolling down the side of the cliff. (00:48:50)
Continuity mistake: When Bond goes to Miss Taro's house, as he enters, one of the blinds is turned on the door, but they were all straight before. (00:49:50)
Continuity mistake: Bond sits down by a table, puts some cards down and pulls his gun out. He's wearing a tie, but when we see a close-up of him screwing on the silencer, his tie disappears. (00:54:40)

Continuity mistake: When Bond is confronting Professor Dent one of his socks varies in height from clip to clip. (00:55:35)
Continuity mistake: When professor Dent throws the gun down it lands on the edge of the bed cover - almost on the floor, but in the next clip it is in the middle of the bed cover. (00:55:40)
Continuity mistake: When speaking to Dent, Bond pulls out a cigarette case. Once the camera changes however, the case is gone and the cigarette is now in his mouth. (00:55:40)
Continuity mistake: During the 'You've had your six' scene, the cigarette in Bond's mouth disappears after he kills Professor Dent. (00:56:30)
