Corrected entry: In the car chase in Vienna, the car driven by Clooney is a Mercedes, yet when the chase is viewed from inside his car, he is driving a BMW 5 series.
Corrected entry: When Nicole and George are attempting to disarm the nuclear bomb, we can see the timer ticking down. Right above the digital display, there is a pause button.
Corrected entry: In the scene where George Clooney and Nicole Kidman are deactivating the bomb in the end, she says the bomb would explode but the church is made of concrete so it would contain all the radiation. But the radiation would have leaked out of the windows since it's not made of concrete.
Corrected entry: The nuclear warheads are from a SS-18 Satan ICBM (Inter Continental Ballistic Missile). These warheads would not be detonated by a timer. They would be much more likely to detonate at a preset altitude therefore an altimeter would be used.
Corrected entry: In the first chase sequence, the hijackers approach the nuke carrying train from behind. They jump on the train. Nobody in the train feels a thud, and then a sniper is shown to slit the throat of the guard standing at the back of the train. He wasn't there before, or he would have seen the approaching train and would have warned the men inside.
Corrected entry: George Clooney's character screwed on a silencer to his pistol during the scene when he was extracting information from the truck scheduler. Therefore, Clooney's pistol must have a threaded barrel. But at the beginning of the chase scene following the killing of Dimitri Vertikoff, you can see the end of Clooney's barrel is crowned and not threaded as he sticks it through the windshield of his car.
Corrected entry: Dusan, the Bosnian guy, sets the timer for the bomb in his hotel room for 10 minutes. The whole church scene from the moment when he is found by Dr. Kelly to the explosion is well over 5 minutes. Are we to believe that the guy left the hotel, walked the streets, took a cab and spent some time in a traffic jam, got chased and shot, altogether covered at least 10 city blocks, and he did it all in a little over 4 minutes?
