Continuity mistake: Bond enters his room and spots Sylvia Trench playing golf. As they talk, she raises the golf club. When the angle changes, she holds it down and raises it again. (00:15:10)
Continuity mistake: In the famous casino scene in the beginning of the film Bond smokes a cigarette, but in the cuts between him and Sylvia Trench he sometimes holds it in his hand and sometimes in his mouth. (00:07:55)
Audio problem: When Bond goes in to see M, you can see Bond speaking just after he sits down. His lips move quite a lot, but there is no sound. (00:10:45)
Continuity mistake: When Bond gets into the car at the airport he is sitting behind the driver (left side of rear seat). In the next shot, he is sitting behind the front passenger seat (right side). In a later shot he is again sitting behind the driver (left side again).
Continuity mistake: During the 'You've had your six' scene, the cigarette in Bond's mouth disappears after he kills Professor Dent.
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: 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)Matty W
Continuity mistake: In the office with Q there is smoke coming from his pipe, when the shot next goes to Bond, there is no smoke at all.
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.
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.
