Factual error: When Yuri's daughter is getting away from the hotel tower, she has to walk to the next building located in front of the tower's window to take the chopper. It should take several minutes, but she does it in a few seconds. (00:48:25)
Continuity mistake: When we first see John, he is in the police shooting range. He has on protective head phones which he takes off and sets on the table in front of him as the other cop comes in. He and this cop talk about Jack, and when they finish, they shake hands. The mid range shot of them shaking hands shows the head phones still on the table. It then cuts to a far shot and now the head phones are gone while the two finish the hand shake. Careful which table you are looking at, as the angle makes it confusing. The head phones were on the table with the red thing on its left side. (00:06:50)Quantom X
Audio problem: In the scene in the banquet hall, where the bad-guy is eating a carrot, he throws it on the floor. Subsequently, while chewing on the little bits he has left in his mouth, there comes a sound which is not a chewing-small-pieces-of-carrot sound, but a biting-a-piece-off-a-carrot sound. That sound was way too loud to have been produced by some little piece he had left in his mouth. (00:47:45)Jacob La Cour
Trivia: Early in production, the film was under the working title "Die Hard 24/7", leading many media outlets and fans to speculate that the film was to be a crossover with another popular Fox property- the television series "24." (An unnamed studio insider even told a popular movie-reporting site that Fox had been tinkering with the idea very early in production to try and shake-up and revitalize both franchises.) The title and concept of the film were subsequently changed.
