Revealing mistake: After the helicopter escape at the end, a red sports car is sticking nose down in the ground after falling hundreds of feet down out of the airplane, without a single crack in the windshield, in mint condition. The yellow one only has the right door open. (01:59:30)
Revealing mistake: During the fight scene in the belly dancer's room, Bond spins the bald guy around to avoid being hit by a chair. When the bald guy gets hit in the back with the chair, you can see a large rectangle of padding under his jacket.
Revealing mistake: During the scene at the restaurant in Montenegro (actually filmed in the Czech Republic) you see a payphone with a Czech Telecom logo on it (itself a piece of history as these are all now rebranded O2). (01:57:50)
Revealing mistake: Bond escapes from the buried pipeline when two technicians open a hatch from the outside. One tech unlocks the hatch by rotating a large wheel which drives the locking mechanism. But when he finally opens the hatch, there's absolutely no mechanism attached. There's just a bare axle that the wheel turns on.
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. (01:42:00)
Revealing mistake: When Bond throws the dead pilot out of the helicopter, you can tell it's a dummy as its arms and legs bend at impossible angles.
Revealing mistake: In the scene with the helicopter chasing them down the street, apart from the fact that the rotors should catch on something and hurl the machine into a wall, when it finally hits the wall at the end, the pilot and crew quite clearly become about 4 crash-test dummies. This wouldn't be so bad if it weren't for the fact that they are unpainted and all sit in their seats looking straight ahead with their hands in their laps while they are driven into a wall. You'd think they could have at least posed the arms over their faces or SOMETHING!
Revealing mistake: In the roof top chase between Bond and Mitchell, it is obvious that both characters are wearing black running shoes, when in the previous scene both wore smart black suit shoes.
Revealing mistake: When Bond is going to the Swiss banker's flat in Bilbao at the beginning of the film, there is a scene where, in the background, you can clearly see people watching the filming. (00:01:15)
Revealing mistake: In the scene where Bond is trying to escape with his new Mini-Jet, he flies through a big hall. If you look carefully, you can see that the aeroplane which is supposed to be flying with its wings vertical is fastened to some kind of sustainer.
Revealing mistake: During the fight on the train between Bond and Grant, you can spot the stunt double for the Grant character by noticing the bad toupee.
