Continuity mistake: After Bond pulls the chain near the mudbath, the mud falls down as a thin stream. In the next shot, it's much thicker. (00:02:40)
Continuity mistake: In the dentist office the cap on the bottle of pills is loose, a shot later it's closed tight and yet a shot later it's missing. (00:10:20)
Continuity mistake: In the Whyte House casino Q plays with the slot machine with his left hand placed on it. In the close-up his hand is gone. (01:30:30)
Continuity mistake: In the battle scene on the oil rig, Bond takes takes control of the crane attached to Blofeld's bathosub. During this sequence the folding window at the front of the crane cab switches between the raised and lowered position several times. (01:47:53)
Continuity mistake: When Thumper dives into the pool after Bond, she is wearing a gold band on her left arm. After she surfaces, it's mysteriously disappeared. (01:52:00 - 01:53:00)
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-wheelers also chasing, but looks like it belongs to the buggy, which has its full complement 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: During the car chase scene through Las Vegas, you can see the crowds lining the streets to watch the filming, yet in some of the street scenes there are no crowds.
Continuity mistake: When Bond climbs the Whyte House to get to Willard Whyte, he climbs a large overhanging structure, leaning out over the main part of the building. But in the previous day shots of the Whyte House there is no such structure to be seen.
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: Bond shoots the Blofeld-copy with a climbing hook. But when did he reload his gun? (And why? He was done climbing).
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: When Bond shoots a Blofeld look-alike, he falls onto the couch, but in the next shot he's on the floor. He couldn't have rolled off the couch, because he's on his back on both the ouch and the floor, and we don't hear him hit the floor.
Continuity mistake: When the policemen are removing the body of Mrs. Whistler from the chanel in Amsterdam, one of them holds her by the bottom of her coat but the shot later, he holds her higher.
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: The diamonds weigh 50,000 carats - which is 10 kg. Nevertheless the toy dog is several times lifted by different persons by only one hand (for example when it is picked down from the shelf in the Circus). They must have incredibly strong wrists.
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.
Answer: If you mean by hiding - why is he never seen normally - then it's because he is a recluse and doesn't like to be seen in public (like Howard Hughes was). If you mean by hiding - why was he not seen during the movie - then it's because he was being held captive by Blofeld and his minions. Spectre didn't want him out and about ruining their plans.
