Character mistake: Near the beginning when James Bond enters the North Korean complex, Zao is sent information to his mobile phone about James Bond being from the "MI6 Security Service". This is inaccurate information because MI6 is the Secret Intelligence Service and not the Security Service. It is MI5 which is the Security Service. (00:06:29)
Character mistake: When Angelo sets the Vulcan down in the sea, he blows the canopy and extends the landing gear. As the plane settles, he attempts to release his harness, then has his air line cut by Largo. He futilely beats on the harness release, when all he had to do was pull the face curtain handles to trigger the ejection seat, which would not only blow him clear of the plane, but would separate him from the seat itself. Having trained for two years, for this specific mission, he would undoubtedly be familiar with ejection procedures.
Character mistake: When Bond is being flown to Baltimore, Pussy calls her assistant Mai Lee twice on the plane. Once in person, then telling the co-pilot to give her instructions. However, when they disembark, she calls her Mai Lai.
Character mistake: There is no way an operative of Q's position and experience would have plugged a device taken from a bad guy into their network. Especially as they had had a security hack only a few days earlier and this was a security establishment. It would have been thoroughly tested and checked on a stand-alone, air-gapped setup first.
Character mistake: On the handwritten label Bond finds, Bratislava is written Bratislavia.
Character mistake: When 007 is interrogating Professor Dent at Miss Taro's house, Dent attempts to shoot him when he asks "who are you working for?" But a minute ago, his gun ran out of ammo when he was shooting at the fake 007 in the bed. So there is no point of picking it up and trying to shoot him. Also, when this happens, 007 says "that's a Smith and Wesson. And you've had your six." This is incorrect, as Dent carried a Colt M1911. However, he did fire six shots before running empty, which is one bullet less than the magazine capacity of an M1911. (00:56:30)
Character mistake: When James enters and exits the laboratory, the door has a sign on it that warns for radioactive materials. The laboratory actually contains a biological weapon. Therefore the door should be marked with a bio-hazard symbol. (00:41:00 - 00:42:00)
Character mistake: Why is Electra using Windows 2000 (still in beta at the time) to survey her oil empire? (I think it's just after she's asked M to come and help her) You shouldn't use beta software for anything important....
Character mistake: When Carver is to go live to the World, his assistant is counting down 5, 4, 3, 2. She does not say 1 and 'Now', as they never do, in order for her voice not to be heard on the broadcast. But if you do the counting, Carver starts before she would have reached 'Now'. Consequently there would be a risk that Carver's first words were not heard on the live broadcast. That would be very unprofessional.
Character mistake: When Bond is jumping from the dam in the opening sequence, you see him 'clip in' twice, once attaching the rope to his feet, and once attaching the rope to the dam. He is using screw-gate carabiners, large clips that have a small bevel gate on them that secure them shut. Yet Bond doesn't screw them shut - all it takes is a simple flick of the fingers and they're done. This means that they're not as safe as they should be, and could potentially open - particularly when doing something as stressful as diving off a dam. You would have thought that as Bond's parents 'had the luxury of dying in a climbing accident' as Trevelyan puts it, he would take more care over basic safety procedures when using ropes and climbing equipment.

Character mistake: James Bond states that the man that fell in the liquid helium would raise the temperature. Since humans have a body temperature of only 98.6 degrees Fahrenheit, falling into a tank of liquid helium at -456 degrees would bring his body down to the same temperature as the surrounding helium in no more than five seconds. (01:49:20)
Character mistake: When Bond is sending his resignation email, another email titled "Stationary Request" is visible in his outbox. The grammatical mistake (it should be "Stationery Request") seems to be an unusual error by Bond and not quite in keeping with his character, his assumed background or his smooth way with words.
Character mistake: At the boat where Bond talks with Colombo for the first time, Colombo has to convince Bond that Kristatos is the bad guy. Colombo takes two drinks and wants to toast with Bond. Bond will trust Colombo and says, 'Yassou' which means 'Hello' instead of what he should say, 'Jamas' which means 'Cheers'.
Character mistake: Sciarra's (pronounced Shara) name is constantly mispronounced Skeeara, even by Italians like the priest at the funeral.
Character mistake: In the scene at Kerim Bey's office, when the bomb goes off, we see a heavy desk topple over. Bey says he was saved because he was relaxing on the couch with a girl. But he wasn't at the desk before either. He was sitting in some sort of sofa arrangement in a different corner of the room. We don't even see the desk before the bomb goes off. (00:32:05)
