Corrected entry: When Bond comes to talk to M in the M16 offices in the early part of the film we see her silhouetted from the back. She is wearing one dangling earring and one clip-on variety. When the shot cuts to a side view we see she has two clip-on earrings.
Corrected entry: When the helicopter is flying towards Bond's old house, it is generally light outside. Just before Silva lands, it is already night.
Correction: 'Generally light' is a big over-statement. It is clear during the raid that the sun is well into 'sunset.' Silva would have planned the raid this way given the limited visibility at night. There are tall mountains at a distance in the surrounding the area, so when you look up at the approaching helicopter is may appear to be daylight but when it reaches the house it would be much darker.
Corrected entry: When Bond is on the tube train he looks at the underground map to see where Silva is going. They get on at Temple, get off at Embankment, the next stop, but after a short foot chase Silva comes above ground at Embankment, after dropping the train on Bond, but Bond comes above ground at Westminster, then proceeds to run up Whitehall.
Correction: After they get off at Embankment the chase leads them towards Westminster, the explosion (and the train wreck) obviously blocks Bond's path from chasing Silva any further. Bond already know Silva is heading towards Westminster so he heads there directly through the underground instead of trying to make his way through the wreckage, climb up and then head towards Westminster anyway.
Corrected entry: Before an elevator moves, the outer doors close. There is no way Bond could have leaped and caught the bottom of a moving elevator.
Correction: Bond doesn't reach the lift through the doors - he uses the free-standing control column as a step to boost himself completely up and over the door assembly. He then latches onto the bottom of the lift as it rises up into the shaft above, which is not enclosed. At no point does he pass through the space now occupied by the closed outer doors.
Corrected entry: Towards the end of the film when James bond gets into the DB5 a modern road tax disc is visible. Cars manufactured before 1 January 1973 [as this car is] are tax exempt, so no modern tax disc would be issued for it.
Correction: Although those vehicles are tax exempt, they are still issued with a tax disc, just for free.
Corrected entry: The caterpillar digger on the train carriage would have been too large to fit through the tunnels later on in the train fight. Lucky it was decoupled or there would have been a serious accident...
Correction: The arm of the digger is in the down position before Bond climbs into its cab. The cab itself is also no taller than the top of the train carriages, so it would have no problem passing through the mountain tunnels.
Corrected entry: During the chase on the London Underground, 007 walks past several Metropolitan Police Officers, however the London Underground is policed by the British Transport Police, who wear different uniforms with a high visibility vest.
Correction: Doesn't mean the police can't ride the Underground.
Corrected entry: Mallory suggest to Q and Tanner that they lay the digital crumbs up the A9 as this is the most direct route. Glencoe is on the A82, not the A9, and in the next scene where the DB5 is entering Glencoe it is the A82 shown.
Correction: Direct route to Glencoe from the South is by driving some part of the A9.
The A9 (unless you do a daft route through little towns like larbert) doesn't start until Dunblane. If you go by the M74/M80/M90 you'd leave to go for Crianlarich road at Stirling, ie before Dunblane. A82 (by Erskine Bridge) still quicker and more sensible route. Better plot line would have been Mallory might have used the A9 deliberately as the breadcrumb route to give Bond /M more time to prepare a defence.
The digital crumbs are going through the Drummochter pass, which is well away from the A82 Rannoch Moor/Glencoe scene and there is no way to connect the two on a car journey without taking a massive and illogical detour.
No it isn't. The A9 starts near Stirling and is central Scotland. The direct route to Glencoe from the south is up the A82 which is well west of Stirling starting in Glasgow. There is no way anyone would drive along any part of the A9 to get to Glencoe, it would involve nearly a 100 mile detour. The scenes shot in the film are just to illustrate they are travelling through the Scottish highlands, they are not supposed to be representative of the actual locations they passed through, ideally they should have taken footage along the Drummochter pass for consistency (Skyfall looks like it is somewhere along there, I'd guess around glen Garry).
No, to get to Glencoe from the South you would drive around Glasgow and pick up the A82, or alternatively pick up the A84 from near Stirling which is just before reaching the A9. In any case, the section of road leading to Skyfall looks very much like the Drummochter pass, which is a section of the A9 that is so far removed from the A82, that it would be illogical to drive through Glencoe. The breadcrumb trail on the map at MI6 shows a direct route along the A9 from Stirling.
Corrected entry: When the Underground train plunges into the basement, the interior lights on the train stay fully lit. As the power for the lights is picked up from the '3rd rail', as soon as that's disconnected the carriages would be plunged into darkness, with possibly the exception of some dim emergency lights.
Correction: The train could well still have lights on. It would depend on the make and model, if the train has a "static converter" and how old it is.
Corrected entry: On the boat to meet Silva. Bond takes the radio, switches it on, and puts it in his right pocket. After Silva has shot the girl and when the helicopters arrive to arrest him, Bond pulls out the radio from his left pocket.
Correction: The "dangling" earring seen from behind is in fact her in-ear communication device.
