Continuity mistake: After Tracy's car passes Bond's, check the stones and constructions on the left side of the curb. Shot changes, we see the car speeding away, and then the shot cuts back to the previous place where the car was.
Continuity mistake: When Bond is finishing up copying the documents in Gumbold's office, with Gumbold about to return via the elevator, a clock tower is shown at 13:59. Without the shot changing, the hands immediately move to 14:00, but some pigeons nesting on a ledge below abruptly change position. (00:42:58)
Revealing mistake: When the white race car with the number 6 is turned over there is a closeup shot of the driver obviously hanging head down in his seat. If you look closer you can see the spectators in the background also upside down. (01:47:20)
Revealing mistake: When Irma Bunt is firing shots from her gun in Blofeld's car towards the end of the movie, Blofeld is a dummy and not Telly Savalas.
Continuity mistake: When Bond started his escape on skis he has laced ski boots. When he throws the guy off the cliff and resumes skiing, he has buckled boots.
Revealing mistake: At the end, when Bond is chasing Blofeld, there is a shot of him hanging onto the edge of a cliff. There is a bit of snow moving up towards him, meaning that this shot is played backwards.
Continuity mistake: In the opening scene Tracy overtakes Bond's car on his left side. However, Bond's mirror shows Tracy passing on his right side.
Audio problem: During the car chase with Tracy, after hooking up in Switzerland, she speaks while driving yet her mouth, while open, doesn't move.
Other mistake: In the bobsleigh chase, when a grenade rolls around Blofeld's feet the rear projection FX suddenly swaps from showing a tunnel to showing a landscape going wildly in circles, as if the bobsleigh had crashed. However, on the following shot the bobsleigh is sliding along the tunnel normally and the rear projection plays the tunnel projection as if nothing had happened.
Continuity mistake: At the casino Bond deals cards to a man on the left. This man's left arm swaps between raised to lowered depending on the shot.
Continuity mistake: After the bobsleigh chase Bond falls on the snow and a dog approaches. The amount of snow on Bond's coat suddenly decreases between shots.
Continuity mistake: During the ski chase it starts off with Blofield and five henchmen, after one gets killed by the snow plough they stop and there are now six henchmen when there should be four. Through out the chase all of the long shots only show six in total.
Other mistake: During the stock car race towards the end, the henchmen sitting in the front right of the Mercedes starts shooting out of the window. He shoots forwards, but Bond is on his left with a white Ford Escort in between them. He somehow manages to hit Bond's car - we see it and hear a ricochet. He shoots several times but always directly in front of him. Bond's car is always on the left, continuous scene.
Continuity mistake: When Bond is fighting the villain on the beach in the pre-credits sequence, the two fight in the sea and Bond's hair gets wet in the process. But when Bond says "This never happened to the other fellow" his hair now appears to be completely dry.
Continuity mistake: When Bond and Che are fighting, Che knocks out one of the white wooden bars behind Bond. However, in the next shot, two bars are missing on the upper half of the wooden structure, one on the bottom half. Seconds later, just before Bond throws Che into it, the bottom half of the structure is complete again, and only one bar is missing on the upper half. (00:14:15)
Other mistake: In the bobsled chase, Blofeld arms a grenade, which drops to the floor of his sled, where it rolls around with every turn. He arms and throws a second grenade onto the track, where it is detonated by Bond's sled. The original armed grenade loose in Blofeld's sled never detonates, even when that sled crashes.
Suggested correction: He never arms a second grenade, he picks up the one he drops and that's the one he throws at Bond. There is only ever one grenade.
Audio problem: When Bond is drowning the attacker on the beach, his head is submerged underwater, yet we can hear him grunting and moaning, as if his head was above water.
Continuity mistake: When Bond is forced to get into the car outside the hotel, the car's roof is down and secured with a buttoned-down cover. However, during the ride the roof suddenly closes automatically although the cover was never taken off. (00:19:40)
Continuity mistake: After Bond has knocked out Che for good, Che's position changes between shots. Especially his legs are in a different position in the wide-angle shots to the shot in which Bond has walked up to him. (00:14:40)
