Mistakes in Diamonds are Forever

Mistake #1

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.

Mistake #2

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 an 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!), which is in the finished film].

Mistake #3

When Bond climbs off of 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.

Mistake #4

When Bond is using Bert Saxby's voice while talking to Blofeld on the phone, Blofeld tells "Bert" to get rid of Willard Whyte. Since Bond is posing as Bert, Bert never got this order. So why does Bert show up at Willard Whyte's to kill him?

Mistake #5

When Bond escapes from the research facility, guards give chase on three-wheeled vehicles. One of the guards goes off an embankment & wipes out. He sets the vehicle up and prepares to drive off. Bond is supposed to run up, kick the guard off & take the vehicle. Connery is so slow in this scene that the stuntman has to sit on the vehicle & wait for him to run up for the kick.
