Factual error: When Professor Dent tries to shoot Bond at Miss Taro's and Bond is waiting for him in the darkened room, the 'Walther PPK' that Bond is busily screwing the silencer onto, at the beginning of the scene, does not have an external hammer, and is therefore not a Walther at all. It's a Browning 1910 .32 calibre. (00:55:10 - 00:56:35)
Suggested correction: Correct to say it's not a PPK, but it's not a Browning either - in a close up one can see the Beretta logo on the grip.
First off, it is certainly not a Beretta. That's not the Beretta logo (3 arrows), but it's the Fabrique Nationale logo (stylized FN). Plus the Beretta has an external hammer and the gun in question does not. It is indeed a Browning 1910 (which is manufactured by Fabrique Nationale. Finally, it is not necessary to submit a correction for mistakes that are accurate but have one or two words wrong (not that this mistake had any words wrong).
Continuity mistake: When Bond enters the office of Universal Imports he throws his hat on the hat rack. After his meeting with M, he retrieves his hat from the hat rack, but it has moved to a different hook. (00:09:25 - 00:14:05)
Revealing mistake: James Bond and his two friends are hiding underwater while Dr. No's thugs search the river with dogs. Bond had very quickly cut three hollow bamboo stalks to use to breathe underwater through the stalks. However, you can see the sections in the bamboo, so the closed stalk sections, separated by the natural divider, would not allow air to pass through. Bond hadn't cleared through the sections with a thin pole, so these would not have been usable as breathing tubes without more work. (01:10:00 - 01:12:00)
Plot hole: When Bond is escaping through the metal ducts, presumably of Dr No's air-conditioning, he is deluged with torrents of water. He then leaves the pipe work through a metal grille into a passageway - why didn't the water leave the same way? (01:33:05)
Plot hole: It's assumed that Dr. No had Professor Dent slip the spider into Bond's hotel room that night but if it were that easy to do that then why not just hide an assassin in the room to begin with. Someone had to be in the room to tamper with Bond's briefcase, the closet, and possibly the bottle of liquor so just hide an assassin instead of waiting for the spider to kill Bond. (00:40:00)
Factual error: Bond is worried that Dr. No has picked up the sails of Honey's boat on his radar, as indeed the good doctor has (in the movie), but radar systems cannot detect cloth or a wooden mast. (01:01:40)
Plot hole: When Bond, Quarrel and Felix sail to Crab Key, Felix says that it's 48 hours to the moonshot. Bond replies that they'll "Be back in 12, if not then it's your beat and you'd better bring your marines with you". We know that Bond was still on the island when the rocket took off (it's when he kills Dr. No) and yet it's only when He and Honey are sailing AWAY from the island that Felix shows up with the marines. Why did he wait the full 48 hours (longer even as the moonshot had already occurred) when it was obvious something was wrong when Bond hadn't come back after the 12 or so hours as agreed? (00:57:45 - 01:43:40)
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: The dashboard of the driver's car that picked Bond up in Jamaica keeps changing colour and brand, from a red 1957 Chevrolet dash to a black 1957 Ford dash. (00:18:25)
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)
Other mistake: After the decontamination chamber scene, Bond and Honey drink a cup of coffee. Honey very quickly passes out due to the tea being laced with some type of sleep inducing drug. However, as Bond throws his cup in anger, Honey flinches very hard. Surprising considering how quickly she passed out after drinking the coffee. (01:20:15)
Continuity mistake: When Bond is firing at the armoured car, trying to shoot the lights out, he begins with an FN Browning Model 1910 but then all of a sudden, it turns into a Colt M1911, a pistol about twice the Browning's size. (01:13:05)
Character mistake: When 007 is interrogating Professor Dent at Miss Taro's house, Dent attempts to shoot him when he asks "who are you working for?" But a minute ago, his gun ran out of ammo when he was shooting at the fake 007 in the bed. So there is no point of picking it up and trying to shoot him. Also, when this happens, 007 says "that's a Smith and Wesson. And you've had your six." This is incorrect, as Dent carried a Colt M1911. However, he did fire six shots before running empty, which is one bullet less than the magazine capacity of an M1911. (00:56:30)
Continuity mistake: At one point Honey is not wearing a bikini top under her wet shirt when they are wading along the creek; the impression of her nipple is briefly visible through the wet fabric. When they are captured she is wearing the bikini top again. (01:06:30)
Audio problem: When Bond awakens on the beach and sees Honey Ryder emerging from the water, Honey is singing "Under the Mango Tree", but when she comes out of the water and shakes her head back, her lips are not moving. (01:00:05)
Continuity mistake: As Bond's driver cuts a hard right turn, the tracks from previous takes are on the road. As the pursuing car draws up to that spot, the dust has quickly settled, and the tracks are suddenly gone. (00:19:05)
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)
Visible crew/equipment: The camera's shadow is visible on the ground as the car goes off the cliff in the car chase when Bond is headed to Miss Taro's house. (00:48:55)
Continuity mistake: Near the end when Dr No attacks Bond up on the gantry we see two shots of the radioactivity meter where the red indicator is very close to maximum. The third time we see it just as they tumble off the gantry, it has moved much closer to the danger level. (01:40:00)
Visible crew/equipment: In the first scene, after the "3 blind men" have killed the man, there is a clear reflection of a spotlight on the black car windows, and at least two men visible - a cameraman and what I believe could be director Terence Young. (00:04:05)
