Deliberate mistake: The famous car chase ends with Bond's car tipping up on its right wheels to fit through a pedestrian path. However, when it emerges the other side, it's tipped on its left wheels. When the car enters the alley, this was filmed in a studio. When the car exits the alley, this was filmed in Vegas. The first few times the exit was filmed, the car emerged on the correct wheels, but the shots were unusable because of the crowds in the background watching the filming. This shot was temporarily abandoned and eventually re-filmed with a different stunt driver who famously performed the stunt on the wrong wheels. Realising this, the producers filmed a somewhat clunky insert shot featuring a close-up of Sean Connery and Jill St John, which shows the car tip back onto four wheels and then up onto the opposite two wheels, even though the alleyway would be too narrow to manage this.
Continuity mistake: When the cops chase Bond in Las Vegas, they all drive by many cars. However, in a close-up inside the police car, one can see an empty road behind.
Revealing mistake: Before Bond is stopped by the cops in Las Vegas and when he is gunned and drives away, one can see it's not Sean Connery driving but his stuntman.
Continuity mistake: When the cops make a U-turn to chase Bond in Las Vegas, the number of bystanders on both curbs decreases noticeably between the close-up and wide shots.
Continuity mistake: When Bond exits the Las Vegas airport, there is a woman in orange surrounded by cabin crew and a parked taxi next to them. A split second later, it's just her alone and the taxi is away, now driving towards her. (00:52:10)
Continuity mistake: When Bond raises the man in the mud's head, the mud is smooth. From an immediate new angle, it's rugged.
Character mistake: When Bond sprays water at the dead man in the mud, he is noticeably struggling to keep still. He even starts to flinch right before the shot is cut.
Revealing mistake: When the guy in the tub gets covered in mud, his swimming cap to protect his head protrudes around the ears. After Bond sprays him with water, the cap is gone.
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.
Revealing mistake: Bond escapes from the buried pipeline when two technicians open a hatch from the outside. One tech unlocks the hatch by rotating a large wheel, which drives the locking mechanism. But when he finally opens the hatch, there's absolutely no mechanism attached. There's just a bare axle that the wheel turns on.
Deliberate mistake: During the moon buggy chase scene in the desert, one of the Ford LTDs crashes and the front fenders, inner fenders, and doors fall off. Even if the car fell off of a cliff, this couldn't happen unless all the bolts were moved previously.
Visible crew/equipment: When Bond climbs off the elevator and hangs for a few seconds, if you look closely at the ground behind Bond, you can see his shadow on the screen behind him, which has the image of the ground projected onto it.
Revealing mistake: When the killer satellite rocket reaches orbit, you can see it 'bouncing' up and down as the pieces separate.
Factual error: While Bond and Franks are fighting in the lift, you can hear glass breaking. However, when Franks picks up a shard of it to stab Bond, you can see it's really a piece of Plexiglass. When Franks is forced to let go of the shard, his hand shows no cuts or blood, which would have been unavoidable the way he had been holding it.
Revealing mistake: When Bond escapes from the research facility, guards give chase on three-wheeled vehicles. One of the guards goes off an embankment and wipes out. He sets the vehicle up and prepares to drive off. Bond is supposed to run up, kick the guard off and take the vehicle. Connery is so slow in this scene that the stuntman has to sit on the vehicle and wait for him to run up for the kick.
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.
Revealing mistake: When Bond is in the trunk of the car, being taken out of the lower level of the Whyte House, a trap door opens out into the desert. The car, however, does not emerge from the door, which is never seen, but appears to be simply driving along a road. The 'door' is apparently a silhouette cutout raised in front of the passing car.
Revealing mistake: When the Hovercraft pulls away, you can see a passenger look out his window and wave directly at the camera. (00:16:00)
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.
Audio problem: In the scene at Willard Whyte's house where Thumper and Bambi are fighting Bond, Bond gets thrown into 3 cylindrical statues. Just as the shot cuts, you can see the last column beginning to topple but there is no sound as it crashes to the floor in the next shot.
Answer: Bond's answer to Felix at customs is "alimentary, Mr. Leiter". As in the alimentary canal of a human.
