Revealing mistake: There is a scene where the Army team is moving through the Colombian jungle. At one point one of the team members has the muzzle of his weapon pointing straight at the camera. You can clearly see the Blank Firing Adapter (BFA), a shiny brass looking thing, in the compensator of his M-16.
Revealing mistake: When Jack Ryan goes to Ernesto Escabeda's residence and asks to see Ernesto, as he is led up to the house we see his two companions on a roof top ledge watching through binoculars and one of them says "He's in", if you look at that shot closely the suppressor on the mp5 laying next to the sniper is fitted at a decidedly wonky looking angle.
Continuity mistake: At the end, when Jack Ryan is arguing with the President, his "A" tag switches from being over the lapel of his jacket to under it, without him moving.
Visible crew/equipment: When the lone Huey helicopter comes to rescue Jack Ryan from a roof top, the reflection of the filming helicopter can be seen in its window.
Factual error: A bunch of troops are in heavy camouflage in helicopters, going to an assignment. The officer in charge tells them to take their dog tags off and empty their pockets of anything that could identify them. This is silly: first, in troop helicopters, the troops wouldn't be able to hear the officer's voice - it's too noisy - and second, this would be ingrained in them, to remove dog tags etc, and would have been done back at the base, before they left.
Continuity mistake: When Jack Ryan is in his office and hacks into Ritter's computer, he is trying to print out some files before Ritter deletes them. His printer fails to print, and after pulling out the paper drawer of his printer he discovers it is out of paper. Immediately, without closing the drawer, he quickly opens the door to the cabinet beneath the printer, grabs some paper, and the very next shot shows the printer paper drawer has mysteriously closed, so he has to pull it out again to add the paper.
Other mistake: The first plane to explode has a very neat symmetrical blast originating from underneath the plane - which is in fact wrong given that only one charge was placed on the side of the plane. The plane would be badly damaged and probably jack knife through the side of the hangar instead.
Other mistake: In Colombia, a heavily camouflaged soldier goes into a hangar and places a bomb on it and rushes out before it explodes. On his way out, he passes another soldier who is lying as close to the ground as possible. In front of this soldier is a line of fine wire, right in front of his face. The only thing I can think of for that wire being there is as a marker for the actor.
Continuity mistake: During the scene in which the convoy of CIA Suburbans is ambushed from the rooftops, Harrison Ford and the remaining men get back in a Suburban that has already been hit and the driver's door is missing. Ford hurriedly jumps into it and begins backing out of the ambush. Even though he didn't buckle it, a seat belt is visible around him. When he jumps out of the Suburban, he doesn't unbuckle the seat belt.
Factual error: When Jack Ryan arrives in Colombia you can see clearly a street name on a plate. That's not a Colombian street plate and it's a Mexico City street.
Revealing mistake: There is a scene where a jet flies over a city which the movie states that is Bogota, Colombia. But those who have been around South America will notice that this scene shows Quito in Ecuador, not Bogota. This doesn't only happen in that scene, but also at the airport scene where the jet lands. You can notice a couple of Ecuatoriana 707s as well as some other Ecuadorean airliners in the background. Also, if this were El Dorado airport in Bogota, you wouldn't see Pichincha mountain, first of all, and secondly Pichincha wouldn't appear so close to the airport as it does if this were to be Bogota.
