Diamonds are Forever (1971) - 57 mistakes

Continuity: 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: 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].

Visible crew/equipment: 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.

Plot hole: 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?

Continuity: Towards the beginning, when Mr. Wint and Mr. Kidd meet the helicopter in the desert, they await a helicopter. After the helicopter lands, while it's rising off the ground, the red stripe across the side of the chopper gradually fades into green. And then, as it pulls away, the stripe abruptly changes back to red.

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.

Factual error: The first laser beam was not generated via a diamond, as Willard Whyte says. The first functional laser device, which was constructed by Theodore Maiman, used a ruby rod.

Revealing: On the Oil Rig, when Bond tells Tiffany to "Shoot 'em." after she gets the gun, three bad guys run towards her. A helicopter drops a bomb in front of them instead, taking them out, but watch the last guy that's the furthest away. The bomb lands a good 20 feet away from him, far enough away not to do any harm. But he crouches a little and stays up, then he looks at his other two crewman a bit clueless, and then falls down a good time later as he finally gets what he was suppose to do.

Revealing: When the Hovercraft pulls away, you can see a passenger look out his window and wave directly at the camera.

Revealing: When Bond is in the trunk of the car, being taken out of the lower level of the White 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: 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.

Continuity: 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: 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.

Visible crew/equipment: When the helicopters are attacking Blofeld's platform, at some points you can see a little black spot moving in background. It is the radio-controlled helicopter which filmed them from behind.

Continuity: After getting beat by Bambi and Thumper, Bond is dunking the girls's heads in the swimming pool. He is dripping wet. A few scenes later, it shows him and the men walking down the stairs to the door, Bond is bone dry. In the next scene where he walks into the room, he is all wet again.

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.

Factual error: When Bond is inside the oil rig, the shots switch from the satellite control room to the satellite itself orbiting. When the satellite fires at the underground missile, it's orbit direction reverses. Then, when it fires at the Russian sub and the Chinese military base, it stops before it fires. This is impossible, as Newtons 3rd law states that for every action there is an equal and opposite reaction. For the satellite to reverse or stop, boosters would be needed at the front of the satellite (of which there aren't any) to counter it's speed. And even if they were there, the direction change and stop wouldn't be as sharp as the movie shows.

Continuity: 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: 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.

Audio problem: In the final scene, Mr Wint and Mr Kid bring in a dinner trolley. When Mr Kid places the desserts top over the bomb, we can hear the timer ticking. Yet, when the dessert is thrown and the bomb is revealed, the ticking cannot be heard.
