Continuity mistake: When Colonel Smithers says "That's not quite fair" during the dinner sequence with Bond and M, the position of Smithers' hand/cigar jumps between shots.
Continuity mistake: When Bond is talking to his contact in the bar after the heroin plant explosion, look in the mirror behind him and you can see Bonita the dancer talking to some other men in the middle of the room. But in the next shot Bonita is on her own walking up the stairs, and the men are no longer in sight.
Continuity mistake: When Bond gets in the car outside the hangar in Kentucky, we see Oddjob open his door to get in. In the close up of Bond in the next shot, however, we see the car door is now closed, but we still hear it closing in the shot.
Continuity mistake: When Bond and Oddjob are fighting to the death at Fort Knox, Bond retrieves Oddjob's lethal steel-brimmed derby hat and takes aim, preparing for a backhand throw with his left hand. Camera cuts to a startled Oddjob for a split-second. When the camera cuts back to Bond, he is executing a much more difficult forehand throw with his right hand.
Revealing mistake: When Oddjob throws his hat at the statue and the camera cuts a close up of it, as the hat goes by the head, you can see the seam (in a freeze frame) where the head is propped up by the filler used to disguise the break. Also, the brim of the hat where the blade is, passes about two inches above the break. Therefore, were it possible, the brim doesn't cut the statue.
