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.
Continuity mistake: When Bond raises the man in the mud's head, the mud is smooth. From an immediate new angle, it's rugged.
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.
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.
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.
Revealing mistake: Many times throughout the car chase in Las Vegas between Bond and the cops, you can see skid marks where they tried earlier stunts with the cars on those points on the road. The most obvious is when Bond pulls away from the Sheriff after he approaches the car.
Continuity mistake: When Mr. Kidd tries to kill James with the flaming shish-kabobs he is wearing gloves, which weren't there immediatly before.
Answer: Bond's answer to Felix at customs is "alimentary, Mr. Leiter". As in the alimentary canal of a human.
