The Sum of All Fears

Factual error: A force of Russian Tu-22 Backfire bombers attacks the aircraft carrier USS John C. Stennis (CVN-74) by sneaking in under the ship's radar. This is all well and good except that carriers usually don't use their own radar, they have Airborne Early Warning aircraft (E-2 Hawkeye's) that can see much further and not give away the carrier's position (let alone the F-14s which would be patrolling too) not to mention the fleet of destroyers other ships guarding the carrier. The whole point is, the US Navy practiced and planned for such a "carrier versus Backfire" battle for years. I guess in the interest of furthering the plot Hollywood has to ignore the immense measures the USN takes to protect those multi-billion dollar assets, not to mention the 5000+ sailors that man them.

Continuity mistake: In the aircraft scenes after the blast in Baltimore, watch the clocks closely. The times go forward, backward, and everything in between.

The Sum of All Fears mistake picture

Revealing mistake: In the scene where Jack Ryan uses the radio after the helicopter crash, the film is reversed - the word frequency appears as a mirror image.

Factual error: In the scene where the dock worker receives the e-mail stating 'the day has arrived', the e-mail is dated Mon, 19 Nov 2002. However, November 19 2002 was a Tuesday.

Continuity mistake: When Ryan is called from bedside to his first big meeting, he is wearing a severely rumpled blue oxford. When he leaves the meeting (with the borrowed tie and jacket) his blue oxford is pressed and starched.

Factual error: The Israeli A-bomb was dropped "at the Golan", yet, the landscape where it is found looks like a sandy desert, and as time flies the bomb is completely covered with a sand dune. The Golan has everything but sands or dunes. The terrain over there is magmatic, rocky and mostly black, as the Golan was an active volcanic area. Had a bomb fallen from the sky, it would most likely remain on the ground, smashed.

Continuity mistake: In the scene on the NAOC (National Airborne Operations Center) E-4B where the plane begins to shake, everything on the conference table, including books, maps, charts, etc., is moving, with the exception of a clear cup of what is supposed to be soda. Not only does the cup not move, but the liquid in the cup (which is most definitely not liquid but plastic) does not move either. It's glued to the table.

Continuity mistake: The nuclear blast blows in the windows at the hospital where Cathy works and all the medical staff is showered with the broken bits. At the end of the movie Cathy doesn't have a mark on her. Even if it is safety glass, the small pieces would still leave nicks, scrapes and small cuts on exposed skin.

Factual error: Why is the President's motorcade so small? There were only a few cars there to protect the most powerful man on the face of the Earth. The President ALWAYS travels with over a dozen Secret Service vehicles, to protect him. Even if when he left the Superbowl was an emergency, all of the motorcade would have left with him also, ruling out the possibility that only some of the cars left with him.

Continuity mistake: Shortly before the nuclear bomb secreted in the bowels of Ravens stadium explodes, an aerial shot of Ravens stadium & the surrounding area is shown. The football game is in progress, but the aerial shot shows the stadium to be completely empty.

Plot hole: When the President of the United States attends a public gathering (such as the SuperBowl) the level of security is extremely high. So why wasn't Mason's delivery on the day of the game checked for explosive devices?

Factual error: When the aircraft carrier is attacked by the Russian aircraft, the carrier is sailing alone. This is not normal as carriers always sail in carrier battle groups, with several smaller ships (cruisers, destroyers) to protect them.

Revealing mistake: In the scene where the president's motorcade is going to the stadium, it travels on overpasses, but there is other traffic passing below. These over / underpasses would have been temporarily shut down as well while the motorcade goes by.

Factual error: 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.

Plot hole: The bomb is found by Bedouin in the Golan (north of Israel). However, it was dropped in the Negev desert (south of Israel). How the bomb managed to move itself 500km is not clear. And Bedouin don't live in the Golan.

Continuity mistake: In the scene where Clark and Ryan come ashore by Zodiac, they are soaked just before they beach the boat, but as they drag it up the beach their clothing (especially Ryan's woolen hat) is bone dry.

Other mistake: At one point during the sub-titled Russian scenes, the word Annihilation is used. However, it was mis-spelled as Anihilation.

Continuity mistake: When Ryan's helicopter crashes to the ground and rolls over, the pilots are thrown partly from the cockpit of the helicopter. When it finally comes to rest, there is a pilot hanging out of the cockpit window. Approximately three minutes later, when Ryan struggles out of the helicopter door, the cockpit window is now empty. (01:07:10 - 01:10:40)

Factual error: Dressler is supposed to live in Vienna, Austria. However, in the final scene, when his car explodes, the county-code on the numberplate is not the one from Vienna, nor from any other county in Austria. What is more the letters have the wrong font and the county emblem is missing.

Factual error: After the US President gives the order to launch the missiles, you see a view of a missile preparing for launch. This is followed by scenes of B-2s launching. The missile shown is an older liquid fuelled missile. The US military retired all liquid fuelled missiles from its inventory long before the first B-2 rolled off the assembly line. As such you wouldn't see both in use at the same time.

President Fowler: Order the planes to stand down, take us to DEFCON-3... and will somebody ask Mr. Ryan if I can use the phone now?

Trivia: When Bill Cabot meets John Clark at the airport in the rain, it was Liev Schreiber's idea to have Clark waiting without an umbrella.

More trivia for The Sum of All Fears

Question: As President Fowler is being escorted from the football stadium, he tells Cabot to "get the people out of here." How did the President know that the bomb was in the building? No one in the scene knew its exact location, so why does he think that if the fans leave the stadium they will be safe?

Answer: The President telling Cabot to "get the people out of here" is just a political life boat. If asked what he did when he found out about the bomb he can "honestly" say he asked for an evacuation.

It's unlikely at such a time of panic that one would consider a 'political life boat'. There's also nothing in the character as presented to suggest that would be his thought process. The president's just been told that there's a bomb in Baltimore (not the building) and says "get those people out of the stadium." He's being evacuated from a location that contains thousands of other people. It's fair to assume he knows all those people are also in danger so wants them evacuated too.
