Continuity mistake: During dinner at the table, when Dr. No crushes the Buddha with his hand, the grip changes positions between shots. (01:29:50)
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? (00:23:40 - 00:41:00)

Other mistake: In the closing credits, John Kitzmiller's name is misspelt "John Kitzmuller". (01:45:50)
Continuity mistake: When Bond first meet Honey, in the first clip, when she's seen from the front, the sun is to her right (there is a bit of shadow on her left shoulder) but in the next clip, when she's seen from the back, the sun's to her left. (00:59:55)
Revealing mistake: Bond, Honey and Quarrel are hiding under the water when the guards arrive. They are not noticed, but one guard comes later than the others. Bond stabs him in the back and leaves him in the water, but there is no blood. (01:08:45)
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)
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)
Continuity mistake: Following their repast, Dr. No instructs his minions to soften Bond up, which they do with great enthusiasm. When Bond regains consciousness in the cell, his brown Nehru jacket, while a little scuffed, is quite presentable. Shortly after, when he removes it to create protection for his bare hands, his undershirt is ripped severely, and there is a blood stain on it. (01:30:30)
