Deliberate mistake: The agent is entering the office approaching his desk where a computer sits with the screen on depicting classified material. Computers left unattended go dark after x amount of time. This computer being in a federal FBI building should be logged out of and not open for everybody to see. (00:19:00)
Deliberate mistake: During his autopsy in Saw IV, it is revealed John Kramer was 52 at the time of his death. Kramer's role in this film is the very early stages of his time as Jigsaw, shortly after his cancer diagnosis, which would put him in his early 50's. However, he looks far too old to convincingly be that young (Tobin Bell was in his mid-70's at the time of filming). He even looks older than he did when he was on his deathbed in Saw III.
Deliberate mistake: Poirot riles up Pennington narrating the story of Grand vizier Ptahhotep who was crushed under the weight of the silver he embezzled. It's a lovely moral story, but Ptahhotep was actually a virtuous administrator and is credited (with various caveats) with writing "The Maxims of Ptahhotep", one of the first books in human history, and there's no record of such a story. It's likely that Poirot made that part of the story up counting on Pennington's ignorance on the subject. (00:44:20)
Deliberate mistake: Wyatt is killed in a park next to El Prado museum (which can be seen in the background). Then S and McQuarry cross the street and appear next to where the bank was. This speeds the pace of the movie, but truth is that the building of the bank and El Prado are 20 minutes walking distance away from each other.
Deliberate mistake: When Willy's fellow prosecutor, Norman, dropped the Crawford preliminary hearing on him, they said it started at 15:00. Willy is in a rush and the whole ordeal takes him just a few minutes. Still, when Nunally accosts him in the parking lot, the movie sped things up; it's nighttime. (00:27:00)
Deliberate mistake: Before Nathan and Karen jump out of Dr. Bennett's car, Dr. Bennett's car is shown taking a sharp turn (close to 90°) and then speeding down the short but steep road. At a high speed, the car should have reached the level road within a second or two. However, Dr. Bennett talked to Nathan and Karen for a longer period of time. When the next exterior view of the car was shown, it was just reaching the intersection and straightaway. The car should have traveled a much greater distance than shown. (00:44:50 - 00:45:59)
Deliberate mistake: When Tree turns on the magnetic medical equipment, it's somehow strong enough to yank a big, heavy wheelchair up and pin Gregory in only a split-second, but not strong enough to instantly pull the screwdriver out of Tree's hand? Obviously this was done so Tree could have a cool moment where she lets go of the screwdriver and it impales Gregory... but it makes no real sense.
Suggested correction: It does make sense. The wheelchair wasn't secured and contained lots of metal, so it was immediately pulled towards the scanner. The screwdriver had a lot less metal, and Trew was holding it very tightly, and she knew what was about to happen, so she should strengthen her grip even more, allowing her to keep hold of it.
Preposterous. Depending on how they're set, MRI magnets can yank entire hospital beds clear across the room, and even once killed a man by setting off a concealed gun he was carrying. There's no way she was holding onto that thing.
Deliberate mistake: Carson's [John Travolta] cat Raymond did not appear to be in the pet carrier when he was running out of the building to his car or when walking to his office and placing the carrier on the desk. (00:02:15 - 00:03:30)
