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)
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)
Revealing mistake: When Bond and Honey are made to take showers to clean them of any remaining radioactivity, they are meant to be naked. When Honey gets out of the shower a man holds a towel up for her, but if you look closely you can see that she is wearing a flesh-colored swim suit. (01:16:45)
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)
Revealing mistake: Every time a shot of the hallway outside of Bond and Honey's room in Dr. No's lair is shown there are several doors on the same side of the hallway that lead too nowhere. Notice when Bond enters the room looking for Honey near the end we don't see the reverse of the doors from the inside of his room.
