Corrected entry: After the nuclear explosion, when the president is in his airplane, he has a plaster on his forehead, then it disappears and without any scar or wound under it. Later it's back again.
Corrected entry: In the scene where the final assassinations take place the cigarette lighter is pushed. Then the camera cuts to a view of the outside of the car right before it explodes. But before it even explodes the car sitting next to it already has its emergency flashers on. Once the car does explode then the car alarm goes off which is when the emergency flashers should cut on.
Corrected entry: In the scene where the soldiers are rescuing the President from his limo they simply rip his door open. It is well known that the Presidential limo is really an armored vehicle that can withstand quite an impact. I doubt that his door would open so easily.
Corrected entry: In the scene where the Russian president is getting into bed with his wife, his pajamas are dark blue silk. When his guards come to evacuate him in the middle of the night, his pajamas are burgundy.
Corrected entry: In the scene in which Russian migs attack the aircraft carrier, the phalanx close in weapon system doesn't fire at the missiles until they are very very close, in reality they would have been fired upon much further out; and as aircraft carrier has 2 CIWS mounts on each side, there would have been another ciws mount firing on the missiles as well, meaning the jets and missiles would not have had any chance.
Corrected entry: During the scene where the dock worker gets the message that "The day has arrived" the date on his laptop says November 19th, 2002. When he receives the bomb he takes it to the Superbowl, which takes place at the end of January or the beginning of February.
Corrected entry: There's been some timeline juggling, but there's still an error after all the mental acrobatics. This film is set before the other three films, even though it's in modern times. However, if the events of Sum of All Fears were supposed to have taken place before Clear and Present Danger, then how come Jack Ryan met John Clark for the first time in Clear and Present Danger yet they work together in Sum of All Fears, which is technically before it?
Corrected entry: After the bomb goes off, Ryan uses the radio in the helicopter, but anyone knows that a Nuclear bomb's EMP (electromagnetic pulse) would have fried anything with an electronic circuit within the blast radius.
Corrected entry: When the bomb detonates, the shock wave hits the helicopter that Jack Ryan is riding in and rips the tail rotor off the helicopter. Without the tail rotor the helicopter should have immediately started spinning out of control and dropped straight to the ground. Instead the helicopter continues forward, arcing downward towards the ground like a fixed wing aircraft.
Corrected entry: Jack is talking to his cell-phone after the explosion. I would like to see the phone mast that would stand a nuclear explosion.
