Continuity mistake: When Bond escapes from the Willard Whyte facility in the desert in the moon buggy, a car that is chasing him goes over a ridge and turns on its side as the buggy speeds by. A wheel rolls back into the shot, all on its own. It doesn't belong to the car, or the three three wheelers also chasing, but looks like it belongs to the buggy, which has its full compliment of wheels all through the scene.
Continuity mistake: After fighting off Bambi and Thumper and dunking the girls in the swimming pool, Bond is dripping wet. A few shots later when Bond and the men walk down the stairs to the door, Bond is bone dry. Then when he walks into the room, he is all wet again.
Continuity mistake: In the opening sequence when Bond runs over and pulls the chain to release mud onto the guy rising up to shoot him, mud clearly splatters all over him as he dives to the floor. When he gets up, his suit is spotless.
Continuity mistake: When the car chase enters a car park there is a blue car in the bottom left corner (from the overhead shot), next to the trailer which Bond makes his escape over. After Bond escapes the car is white (I think) and may also be pointing the opposite direction.

Continuity mistake: When Bond and Tiffany are having their dinner on the cruise liner, Bond makes comments about the wine and you can see behind him there is a liquor bottle on the food cart with a large white label facing the camera. When Bond is being strangled by Mr Wint and reaches for the bottle to smash and throw the contents at Mr Kidd, the bottle is turned and the label is facing away from the camera.
Continuity mistake: In the opening scene Bond smashes the giant light on top of Blofield and he falls across the table, but in the very next scene when Bond fastens the strap, Blofield is lying horizontal to it. This is a continuous scene.
Continuity mistake: At one part Bond is talking on the phone. He is wearing a pink tie that goes to the second button on his shirt. Then in the next scene before he meets up with Thumper, his tie is longer.
Continuity mistake: When Bond releases the red weather balloon from the oil rig and it is spotted by the guys in the helicopter you can see a desert/land background behind the helicopter despite it supposedly flying over the sea close to the oil rig.
Continuity mistake: At the end of the film, when Ms. Case is on Blofeld's oil rig in the control room, her butt crack is seen at the top of her bikini. A shot later, it is hidden.

Continuity mistake: When Mr. Kidd tries to kill James with the flaming shish-kabobs he is wearing gloves, which weren't there immediatly before.
