Revealing: When Bond throws a Blofeld henchman off a cliff near Piz Gloria in the Alps you can see that it is a dummy as it's arm swings round and wraps around the whole dummy.

Audio problem: In the sequence of a party in Portugal, when Bond runs to Tracy to appologize after saying something umpleasant about her, he grabs her and starts talking with his back to the camera. His face muscles don't move - the scene was later dubbed.

Audio problem: In the opening scene, Bond sees the women in the ocean and drives his Aston Martin on the beach to rescues her. When he stops, we hear screetching tires, but he is driving on sand.

Factual error: Of all the characters, major and minor, who ever speak German in Switzerland, not one speaks Swiss German. The accents are very different (Swiss German can be almost incomprehensible to speakers of High German), and there's also different vocabulary. While some of the characters might just be non-Swiss speakers of German, at least the underlings at Piz Gloria should be speaking Schwyzerduetsch.

Continuity: After Bond saved Tracy from drowning (at the start of the movie), he is fighting with the two men of Blofeld. In the first shot they're standing about 5 feet from the waterline (on the beach), in the next shot they're waist deep in the ocean.

Visible crew/equipment: When Bond is being chased on skis, he flies over a ridge and through some trees, landing very close to the edge of a cliff. A cable is clearly visible tied to his right ankle to keep him from going over the edge.

Continuity: When Blofeld gets thrown from the bob-sleigh and gets his neck caught between the branches of a tree, he is caught under his arms in the long distance shot.

Plot hole: Blofeld is played by Telly Savalas. In a previous film, Blofeld had met James Bond and had ordered him killed, yet in OHMSS, when Blofeld meets James Bond, he doesn't recognise him. It's well established over the course of the Bond movies until the reboot with Casino Royale that they all take place in one timeframe, so they should have recognised each other.

Audio problem: In the scene where Irma Bunt has seen the girls off in the village and starts chasing Bond and Tracy, tire screeching can be heard from her black Mercedes. As it is driving on snow, such a sound is not possible.

Continuity: In the scene where Bond rescues Tracy during her suicide attempt in the sea, a ship can be seen in the sea slightly to the left as Bond goes after Tracy. In the next shot, where he carries her back to he beach, the ship has disappeared.

Continuity: At the start of the scene where Bond is helping with the assault on Piz Gloria, look at Tracy's hand just after the bald guard presses it down on the object to unarm her. You can see blood, but a couple of minutes later when she kills him there is no blood to be seen. (Time)

Continuity: When Bond is preparing his luggage, the objects in his suitcase changes between shots. Submitted by Dr Wilson

Audio problem: In the scene where Bond and Tracy are in the car race on ice, Tracy is heard to say "James, how do we get out?" but her lips don't move at all in the accompanying close-up.

Other: In the scene when the helicopters arrive over the research center, look at the heli in the bottom right - it just fades out, while one on the left materialises, and the one in the middle changes position. Notice that after all the helicopters have changed place, you can see the helicopter that faded out appear on the helipad (Time)

Continuity: In the beach scene where Bond rescues Tracy and fights the goons, cloud cover changes continuously between shots.

Continuity: In the car chase in Switzerland Bond and Tracy are being chased by Blofelds men, and at one point the Mercedes with the bad guys swerves off the road. But in the inside shots of Bond and Tracy's Cougar you still see the Mercedes' headlights, still on the road, in the rear window.

Continuity: In the stock car race scene, when Bond and Tracy first drive onto the track the number 11 red car spins out to avoid a collision and ends up facing against the wrong way. Two seconds later we see the number 11 car backing up so as to face the correct direction. Two seconds after that, in a long shot, we see the number 11 car going forward again. A few seconds later we see the number 11 car facing the wrong direction as it begins backing up again. Several seconds latter, the Mercedes containing Blofeld's henchmen enters the track and once again the number 11 car is stopped facing the wrong direction. Later in the scene the Mercedes collides with the number 11 car causing it to spin out and end up facing the wrong direction, yet a few seconds later we see the number 11 car racing along in the correct direction as Bond and Tracy pass it.

Audio problem: When Bond is talking to Draco at his house, Draco is telling Bond about his daughter Tracy. As he sits down on the sofa next to Bond, brushing cigarette ash off his suit jacket, he is clearly and rather badly dubbed. (Time)

Continuity: When Tracy is battling that balding guard during the climax, she finishes him off by pulling him into a metal patterned wall in a way that ends up with one of the circular sections on his head like a crown. When he falls down the stairs this circular section disappears. (Time)

Continuity: During Draco and Bond's attack on the clinic, a scientist throws a container of acid at Bond and it hits a glass door and eats a hole in it. In the very next shot after Bond has gone through the door, the hole is no longer there.
