Revealing: Whilst in Q's workshop, Bond places his envelope on Q's X-Ray Document scanner. If you pay close attention to the screen (it's easy to notice anyway) his flight ticket has got VOID written on it 4 times... (Time)

Continuity: When Bond and Natalya are being chased through the library by Orumov and his soldiers, Bond pulls out his belt and activates the piton with the high tensile cable. It goes into the wall just above the arched window. Before the camera angle changes to show the point of contact with the window, Bond is facing forward. As he hits the window he is suddenly facing backwards. Then as he exits the window, the camera outside shows him to be facing forwards again.

Other: When 007 escapes from Ourumov, he shoots dead several Russian soldiers (two of them from the floor), jumps through a window, and smashes through numerous walls in the tank, yet his suit when he gets into Trevelyan's train is perfectly dry-cleaned and unblemished.

Continuity: When 007 and Natalia are in the plane flying over the pond and looking for the dish, Bond says "Maybe Wade was right. There is no dish." As he is saying this you can see that they are leaving the pond behind. This is obvious as you can see the trees on the same side they are flying over. Yet the missile shoots out of the pond and hits the wing while the plane is over the pond. There would not have been enough time to turn the plane round and go over the pond again.

Revealing: In the scene containing Q describing the operation of the "grenade" pen to Bond, Q is not looking at Bond and appears to be being cue'd. With careful observation you can see Q's eyes reading the cards. Also, his actions/reactions do not seem fluid but abrupt as he reads to a point where he must do an action of some sort and he performs it suddenly. Much of the scene is shot from a profile view of Q and Bond so as to reduce the obviousness of it (mostly during the longer dialog pieces for Q).

Factual error: In the tank chase scene, Bond drives through the concrete wall with the turret forward. This would absolutely wreck the gun. Also later the tank is sliding around on the road. A real tank wouldn't do this, it would rip up the road.

Plot hole: Boris changes the satellite's orbit to be over London instantaneously via computer. Re-tasking a satellite takes days, even weeks.

Factual error: The loco pulling the train is in fact a British Rail class 20 diesel disguised as a snowplough and not actually Russian at all.

Continuity: When Bond visits Q to check on the latest gadgets, Q sits in a wheelchair with a below left knee plaster, which later on shoots a type of grenade into a dummy. Once Q has fired this missile in the very next shot he stands up from the wheelchair in trousers and shoes with not a sign of the whole plaster cast. (Time)
