Revealing mistake: During the draining of the water in the dish, some shots show the water moving backwards. For instance, at a particular moment, masses of water jump UP, ark toward the opening, and fall in it. The most likely reason is that, during the filming, the special effects people took a shot of a replica of the dish FILLING with water, then edited it the other way, to show that the water was emptied from the dish.
Continuity mistake: James Bond does his bungee jump down a dam that looks like it's in the beginning of spring, but when he emerges from the factory, it is dead winter with no dam in site, since they are on a mountain top.
Continuity mistake: When Bond and Natalia eject from the helicopter, you can clearly see two white parachutes, but when the capsule lands, in two scenes you see the parachutes being red and white.
Continuity mistake: In the tank chase scene, when Orumov's car goes down the alley the head light and corner of the car are smashed, but when the car emerges from the alley, the corner is intact.
Continuity mistake: At the end, all the marines reveal themselves, to the surprise of Bond and the woman (fair enough). But at the same time three helicopters come in from the top of the screen, which apparently no-one had heard or seen until that second. Odd, especially since they only start making any noise when they're in shot...
Continuity mistake: At the start of the movie where Bond is fighting the man on the runaway plane, Bond jumps out of the plane with the pilot (they hit the motorcycle). In midair Bond has no gloves on and when he gets back on the motorcycle, he has black leather gloves on.
Continuity mistake: During the pursuit scene in St-Petersburg, two military trucks breaks a fence and fall in the water. The first one contains 2 passengers, but 3 are ejected from it and the second one contains 3 passengers and 2 are ejected from it. More strange, the one with 2 passenger was behind the one with 3 passengers some shots before. I don't see why they would chase between them.
Visible crew/equipment: This flub is virtually impossible to catch by the human eye - use slow-mo. When Bond jumps off the dam, they do a shot, following him along his descent down the ledge of the wall. In a shot only visible during three or four frames, but they catch a shot of the ledge before panning down, in which you can see the film crew watching on top, together with a van or two...
Continuity mistake: At the beginning of the film when Bond is cutting through the access hatch with the laser, you can clearly see that the laser is constantly shaking about yet the cutting is in a perfect line.
Factual error: At the climax of the movie, when Bond is holding Trevelyan by his foot over the dried lake and the dialog exchange of "For England, James?" "No... for me.", Bond lets go of Trevelyan. He then falls a very long distance onto solid concrete. A short time later, the movie shows Trevelyan still alive and moving his head around. This is not possible. A fall from that that height, especially falling on concrete, would have killed him instantly. The shot of him hitting showed him landing on his head and back first. This would have crushed his skull, and snapped his spine. Even if that didn't kill him, it would have knocked him out cold. The mistake goes even further though. The antenna array then explodes and falls on Trevelyan, while he screams at the top of his lungs. Even if someone was somehow able to survive that fall, the damage done to their body would have caused massive internal damage and bleeding. Trevelyan's lungs would have filled with blood. There is no way he could have screamed, let alone that loudly. So this mistake is twofold. The fall would have killed him instantly. And even if not, he could not have possibly screamed.
Continuity mistake: After the American agent "delivers" the Cessna to James Bond and Natalia, they make several passes over the lake in Cuba. Then the plane is hit by a rocket. Right before they crash the plane, it becomes a different plane. The original one is white and maroon. The one that crashes is white and red. It happened too fast to check the N-Number or registration, but the second plane was an earlier model as well.
Continuity mistake: When Bond exits the chemical factory, his hair is noticeably shorter than it was when he was inside. Apparently, the conveyor belt tunnel had a barber.
Continuity mistake: When Alec confronts Bond in the storeroom at the beginning of the film, he's seen pointing a suppressed Browning BDA at him; however in the other scenes the gun switches to an anachronistic Browning BDM (as this sequence is set in 1986). The BDM is what Trevelyan uses during the climax.
Continuity mistake: Opening sequence when Bond bungees off the dam, you see him lay down the bungee cord he uses, it appears to be no more than a couple meters of cord. Seconds later there is a shot of the dam itself, panning upwards from the bottom. The dam appears to be several hundred meters high, not a chance that tiny cord is enough.
Continuity mistake: In the scene when 007 is in Monaco, he takes a photo of the admiral and his female company. When he is calibrating the camera its to one eye. In the other shot he has the camera to the other eye.
Continuity mistake: When Bond and Natalya fly over the artificial lake, a missile is fired from within the lake. Where did this missile come from? Once the lake has been drained and the dish emerges there is no submarine stranded there nor can you see a missile battery.
Continuity mistake: In the bottling room scene, 006 holds his gun hanging down in his left hand. Then after he activates the alarm, it shows the gun in his right hand.
Plot hole: In Cuba, Bond and Natalia are in a plane flying over a lake, attempting to find the Goldeneye control station. The station is hidden, and the Janus Group inside obviously does not want the operation discovered until it's time to go with their plan. They are hidden so well, Bond and Natalia are about to give up. Yet, the enemy fires a rocket at the plane to shoot it down, and sends Xenia in pursuit to finish them off. This does not logically make sense, as the rocket would be a dead giveaway that the base is actually there and lets Bond know it. That, and the rocket would be seen by the US government, letting them know that Janus is there. So even if the rocket succeeds in killing Bond, it would give the US government a precise target and would undermine Janus' entire operation. The logical thing to have done would let Bond leave empty handed.
Factual error: When the Goldeneye satellite is repositioned for targeting, the display shows a retrograde, east to west orbit. Only a couple of satellites have been sent into retrograde orbits. One use would be for a killer satellite that smashes into other satellites, not one that is hiding in plain sight until needed. A retrograde orbit is no faster than a standard orbit at the same altitude. Not only that but since a retrograde orbit is much more difficult and costly (in terms of fuel and other resources) to achieve, due to working against the Earth's spin instead of benefiting from it, very few satellites use one. This makes the addition of one in Goldeneye something that would draw extra attention from foreign powers, the exact opposite of what a country launching a super-secret satellite weapon would want.
Visible crew/equipment: When Bond is just about to dive of the dam, the camera has a view from over his shoulder. You can just about make out over on the far left a car park with film crew vans and trucks. There is also much further down the dam a crane with a camera on.
