Visible crew/equipment: There is a shot of Holly crawling through a tight space with the camera facing her moving backwards as she crawls forwards (about 30 minutes into the film). In this shot, the wheel marks of the camera can be seen on the ground in front of her. (00:30:05)
Plot hole: Bond makes a huge tactical error after diving to the St. Georges. He knows the Russians and their operatives are after the ATAC. The ATAC itself is expendable to Britain, since it has a self-destruct mechanism that, under proper procedure, would have been set off when the ship sank. So why is Bond trying to retrieve it? Because he disarms the self-destruct, he actually allows Kristatos to get his hands on it, forcing Bond to track it down again and, to stop the Russians from getting it, HE DESTROYS IT! So why doesn't Bond, instead of disarming the self-destruct, set a timed charge or toss a grenade in the room to destroy the ATAC while it's at the bottom of the sea? The answer is, of course, that if Bond destroys the ATAC before the bad guys can get at it, the movie's over. Even so, at the end, when Bond finally does destroy the ATAC, he tells Gogol it's "detente. You don't have it. I don't have it." Clever line, but it reinforces the fact that the British don't need it. They can build another one.
Continuity mistake: At the beginning Ava shoots the man's phone out of his hand through the car window. When the car drives away all the windows are intact.
Continuity mistake: During the chase scene on the bridge involving the tank, two cars (silver Toyota Corolla hatchback, licence NE34 12 and a black VW Bora, licence NU67 67) appear during many shots, often travelling in different directions on the bridge and either ahead or behind the chase.
Factual error: Jack Ryan takes the enlisted oath, not the officer's oath, when commissioned into the Marines. (00:02:35)
Factual error: In the balloon scene, it seems like Q can circle around and land on a spot where he flew past previously. A balloon can only fly in the direction of the wind.
Continuity mistake: When Peyton returns to his lab after its destruction, a burnt picture of him and Julie is on the floor. The destroyed picture shows half of Peyton's face missing. After finding a new place to stay, when the picture is put into the scanner, more of Peyton's face is visible. (00:28:10 - 00:30:40)
Factual error: How would the creature be able to re-enter the ship by climbing into the reactor piping? The reactor fuel system is not open to the living space of the International Space Station.
Continuity mistake: After Sarah and Rios come out from the flooded cave, their clothes are bone dry even though there were almost fully submerged underwater. (01:01:25)
Other mistake: When Catherine breaks into Crown's house, her assistants immediately get to work on the security panel. When the first assistant touches the panel, it falls off the wall and he has to quickly push it back into place.
Factual error: On the bus ride in Nepal, they're playing a Hindi song from an Indian movie (Kabhi Khushiyan Kabhi Gham) that was released in 2001. The time frame on the bus is 1996.
Factual error: It's mentioned that the British and New Zealanders turned the Americans away. This is untrue - the Americans stayed with both for a time until it was decided that they would be safer with the Canadians.
Continuity mistake: When the incomplete second EAM is shown in the movie for the first time, its subject line states "nuclear missile launc..." However, when this same message is finally received at the end of the movie the subject line states: "terminate launch all missiles". If the first one had been consistent with the second this would have made quite a difference. (00:55:45 - 01:45:25)
Factual error: When the house explodes, there is a massive explosion and fireball that creates a pressure wave strong enough to send Brian flying into the van. However, not a single window breaks on the houses just feet from the explosion. (00:15:40)
Visible crew/equipment: When Freddy falls over the banister onto the stairs near the end, notice the crash mat he lands on. (01:18:55)
Factual error: The Pentagon is the largest office building in the world. It has seven floors, 28 kilometers of corridors and 620,000 square metres of office floor space. The idea that the entire building could be searched in one afternoon by six people is beyond absurd. If those six people could search an average of one office every five minutes and they worked twenty four hours a day, seven days a week they'd get through the whole building in 89 days and 15 hours. I don't think the punter they are looking for has a lot to worry about.
Continuity mistake: In the scene where Ruby and brother are driven to Terry's crash site the police cruiser changes from a 98 model to a 97 model. The vehicles headlights, front bumper and over all design are completely different.
Continuity mistake: In a scene towards the end of the movie, where Bond and Vesper are lying on the beach, Bond has sand on his back throughout most of the scene. When they start to kiss, in the distant shot towards the end of the scene, he has no sand on his back at all. (01:57:10)
Continuity mistake: In the scene at the bar with Gideon when the black guy pours Gideon a drink it is only about 1/3 full. When Gideon drinks it in the next shot it is almost full.
Visible crew/equipment: You can see the string that pulls Bubba off the bike when Max shoots him. (01:19:41)
