Corrected entry: Near the end of the film, when Langdon rewinds the security camera footage on Commander Richter's PC, the sound heard is that of a recording tape being rewound. A PC wouldn't make the squeaking sound of recording tape being dragged over a magnetic reader. The rest of the equipment at Richter's desk is fairly high-tech, so it's fair to assume that the surveillance cameras too were digital.
Corrected entry: All the TV crew vehicles on Saint Peter's Square are Ford E-Series vans, which is a US-only model. While some, those used by US networks, could have been exported, European networks would have no reason to do so.
Corrected entry: When the hitman throws Cardinal Baggia to the water and salutes Langdon, he closes the van's door, but when he's running away the van's door is open again.
Corrected entry: About 20 minutes into the movie Professor Langdon talks about the set of 5 brands used by the Illuminati, from which the first 4 represents the elements (earth, air, fire, water). When in the end reaching the Castle St. Angelo as the Church Of Illumination and discovering the set of brands in person he is surprised to discover there's a fifth brand.
Corrected entry: When we first see the Illuminati assassin in the scene where he has the four Cardinals locked up behind bars, he speaks in an American accent, ("If God has a problem, it will not be with what I have done but what I am about to do"). Later in the film he speaks continuously in an Italian accent.
Corrected entry: When Robert and Vittoria visit the first church in the Path of Illumination, the sun is still up and it is fairly light. However when they go to the next church (St. Peter's Square) less then an hour later, it is pitch black. Surely the light levels can't change so drastically in one hour?
Corrected entry: It is said that the four Cardinals will be publicly executed. However, most of the executions are not in public, but instead in areas where no-one is around.
Corrected entry: The Camerlengo takes the antimatter up in a helicopter to save others from the explosion. However, if the blast is large enough to destroy Vatican City, it could have stretched vertically far enough to reach the ground. It would also certainly destroy any aircraft in the blast radius. It is unlikely that a religious man would choose to move the canister, and therefore "playing God" by choosing who lives and dies.
Corrected entry: The first Cardinal is supposed to be executed at 8 p.m. However, the setting is light, and does not look at all like evening.
Corrected entry: If the illuminati were not truly still active, then the Camerlengo would have had to solve the same puzzle as Langdon. Not Likely. And an extreme cover to get the nuances correct if it were a cover story. If the illuminati were still active, the Camerlengo would have to be a member. Why at the end of the film was no one therefore concerned to go after them as well?
Corrected entry: Boca Davie's comment was interesting and I have an addition to that scene. When Dr. Vetra placed her chin in the cup for the eye scanner and subsequently discovered blood on her chin, she was on the outside of the lab door. When she proceeded, she found the eyeball and the dead scientist inside the lab. If the assassin was let into the lab by the scientist, why did he need the eyeball to get out and if he did need it to get in, how did he get it in the first place if the scientist was inside? All irrelevant: if he somehow gained access and ripped out the eyeball to get out undetected, then the blood should have been on a scanner on the inside of the lab, not the outside.MainesladyB
Corrected entry: The "bomb" comprises anti-matter suspended in an electromagnetic field; while anti-particles have charge and can be suspended like this, anti-matter doesn't and can't. Even in the event of it being called anti-matter as a character mistake, the amount of energy required to keep such a large amount suspended would far exceed the energy that could be produced by a battery, therefore the whole concept of a "bomb" that could be carried around is false.Med
Corrected entry: It would take 2 billion years to make just 1 gram of anti-matter in a best-case scenario. According to CERN, if they annihilated all the anti-matter they have ever created, there would only be enough energy to light a light bulb for a few minutes, so an anti-matter bomb is fanciful to say the least.Med
Corrected entry: The Vatican Archive is portrayed as a super-sophisticated complex of sealed chambers with controlled oxygen levels, and hallways that stretch seemingly far into the distance. As a quick visit to the Vatican website reveals, the Archive facilities are considerably more mundane and humble, looking much like an ordinary university store of old records and other literature.
Corrected entry: After the cylinder is stolen from CERN, Vittoria explains that it is filled with a "highly combustible material": antimatter. Combustion is a chemical reaction, whereas matter/antimatter annihilation is a much more basic sort of quantum mechanical interaction. A layperson might make the mistake of referring to it as combustion, but a professional physicist never would. A more accurate word would be "volatile".
Corrected entry: As the chains are set free, Cardinal Guidera appears to completely fall into the fire to burn to his death. However in the next two shots, he is still suspended above the fire by two apparently taut chains.
