Corrected entry: When Ryan and Clark are flying to Russia to look for those missing scientists, Clark shows Ryan some satellite pictures of the remote area where they suspect the scientists to be located. The day old photo shows activity in the area but the most recent one doesn't. They then discover that the bomb is headed for the U.S. and Ryan phones the CIA to warn them, But the bomb is already there! How did the bad guys manage to get the bomb from that remote location in Russia to a freighter and sail it to the U.S. in one DAY! This is something that should have taken weeks, which would have given Ryan plenty of time to get home and prevent the attack.
Corrected entry: When Ryan finishes talking with Spinnaker before he goes to the docks, he leaves the car he borrows and heads out through the flames. In the background, you can see a stunt coordinator waiting to guide him through the flames. He waits, then follows him off the screen.
Corrected entry: When Dressler's 'secretary' speaks 'German' it doesn't sound German or Austrian at all. In fact I am Austrian and If there weren't English subtitles I wouldn't have understood at all what he's talking about. Yes, there were German words, and maybe even the grammar was more or less correct but the pronunciation was that bad that the whole audience started laughing when they heard him talking in 'our' language.
Corrected entry: In the scene where the bomb was detonated, and Jack Ryan's helicopter is blown to bits, the laws of plutonium dictate that if Ryan was as close to the blast as he was, he would have been dead from radiation poisoning within a couple of hours.
Corrected entry: At the end when Dressler's car explodes a piece of it ends up on top of a Jaguar, then when the camera pans back the Jaguar is not there.
Corrected entry: B2's never leave the middle of the United States unless they are in the air and are on their way to bomb something. The B2's would never have been stationed in Italy and could never have attacked Russia that quickly, as they would have to travel halfway around the world.
Corrected entry: During the scene at the end of the film where both presidents are sitting signing documents in front of an audience, both start signing left handed, but the Russian president signs the second document right handedly.
Corrected entry: In the sequence where Ryan's helicopter has been hit by the blast of the nuclear explosion, an acoustic alarm goes off during the tailspin. This wouldn't be possible, since every electronic equipment fails after a nuclear explosion due to the nuclear electromagnetic pulse.
Corrected entry: In the scene where Senior Russian officials are entering the underground base of operations, the president is told that American nuclear submarines are pulling out of Norfolk and Kings Bay armed with Trident D3 weapons. This is a mistake for two reasons: a) I speak Russian and I heard them say Trident D5, not D3 and b) American nuke subs are no longer armed with D3 missiles, they have mostly D5's, some have C4's. Also, I'm pretty sure D3's aren't considered first strike weapons, whereas D5's are. (01:32:35)
Corrected entry: When the bomb explodes at the Super Bowl in Baltimore it is daytime, but the Super Bowl is always held at night.
Corrected entry: One thing that is created by a nuclear blast is an electromagnetic pulse. This radiates out of dozens to hundreds of miles at the speed of light. The pulse fries all electrical equipment whether they are on or not. Cabot's palm-pilot, and all cell towers in the city would have been destroyed so Ryan couldn't have used it to call Spinnaker. (01:29:15)
Corrected entry: Why does Clark find it necessary to cut the Ukrainian fence at all? When the guards discover the hole, we can see that Clark began the cut nearly a foot from the top of the fence. In fact, it is barely 8 feet high - with no barbed wire and a smooth bar at the top. Climbing over it (as opposed to cutting it) would have prevented the guards from detecting his presence. Maybe this is why they don't trust him with an email account.
Corrected entry: When the call comes for the bombing of the aircraft carrier, you think that there would be a chain of command with sort of checkpoints to ensure accuracy and to ensure something terroristic would not happen. They probably did this to keep the plot flowing, but it still seems illogical.
Corrected entry: Shots that are intercut between the scene involving the President's attending the Super Bowl in the football stadium in Baltimore and the shots outside the stadium involving the explosion of the nuclear device and the resulting destruction and loss of life are clearly intended to occur during the same time frame. However, all shots set in the stadium are at night under a darkened sky, and all shots outside the stadium take place in the full afternoon sunlight.
Corrected entry: About an hour into the movie, when Ryan meets Clark after he is ambushed by the two Ukrainian officers, there are a number of mistakes. For one thing, the officers are not speaking Ukrainian, but pure Russian. Secondly, Clark asks Ryan to tell them to take their shoes off - but we've already seen that Clark knows Russian, when he talked to Spassky's mother. Why doesn't he tell them himself? After that scene, he remarks to Ryan, "You know Ukrainian?"... however Ryan too, just like the "Ukrainian" officers, was speaking Russian. (01:00:30)
