Continuity mistake: When Professor Dent arrives at Miss Taro's house where Bond is waiting, he shoots at a fake Bond in the bed and eventually runs out of ammo, which causes the slide on the gun to lock back. However, when he is interrogated by Bond and drags his dropped gun to himself with his foot so he can shoot him, the slide is now locked back into normal position.
Continuity mistake: When Dr No, Bond, and Honey are eating dinner, Bond picks up and flexes a table knife. Then there is a wide shot where his hands are under the table. The next tight shot shows him again flexing the knife, then once again goes to the wide angle showing his hands under the table.
Revealing mistake: When Bond fights Quarrel and Pussfeller at the back of restaurant we can see that Pussfeller is replaced by a stunt double.
Continuity mistake: When Honey is with Bond on the beach, she is holding two shells by her chest and lowers them when she is talking to him. But when the camera angle changes to behind Honey in the next shot, she is now holding the shells by her chest again.
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.
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)vtology
Other mistake: In Strangways' house, Bond picks up a framed picture. Just as the other person comes into the shot the image skips.
Revealing mistake: The second car chase is made with the help from a greenscreen. The car's movements as seen on the background doesn't always correspond with Bond's steering and the following car is sometimes too close to the screen.
Audio problem: When the radio controller in London says "Hello, W6N. Report my signals", his lips don't move.
Continuity mistake: When Honey is telling Bond that her shells could be sold for $50 in Miami, not only does the background appear to be the wrong section of the beach (it looks like the area up where her boat is stashed, not down on the sand bar) but at the bottom of the screen, some kind of buoy or flotation device bobs up on the water just behind Ursula Andress. A couple shots later, however, when they're running along the beach, the whole area is completely clear. (01:04:35)Garlonuss
Continuity mistake: When you see Bond in his hotel room for the first time, there are two bottles on the table, a clear one and a green one. When he re-enters the room and checks his traps, the green bottle has disappeared. Bond takes a bottle from a drawer but that also is clear so what happened to the green one?

Continuity mistake: When Dr. No crushes the gold Buddha statue at the dinner table with his hands, it falls off the table onto the floor. However, when a wider camera angle is shown, right before the guard takes Bond to the elevator, the gold statue is back on the table. (01:29:05 - 01:29:50)Matty W
Continuity mistake: At the baccarat table at the ambassador's club, Sylvia Trench has a red dress on. A piece of the dress off of her shoulder. In the first shot, this piece goes to the left about three inches from the broach she is wearing. In the next shot, the piece hangs down, covering half her broach. (00:07:00)Matty W
