Other mistake: In the pre-credit scenes when the chopper spots the runaway car, Driver guns it (he clenches his jaw, fists and you hear the engine revving and gears changing) but he never catches up with the two cars only a few feet in front of him (which are proceeding at normal speed) for the whole length of the bridge.
Other mistake: The knife used in the Argentina pub scene never has any blood on it, despite being driven into one man's stomach and another man's hand-twice.
Other mistake: Throughout the entire chase scene at the end, the vault creates sparks on the road. Yet when they get to the bridge, no sparks appear. This cannot be due to the vault being empty at this point, as the vault itself is 10 tonnes, as mentioned earlier in the film. (01:49:00)
Other mistake: When the chief of police is introducing Porter Nash as the new Acting Inspector he shows a copy of a paper which, if you look carefully, tells about a second cop being shot. Later in the film, the second cop is shot and then the chief is shown to be reading the same paper. (00:13:25 - 00:18:15)
Other mistake: Will did not have enough time to place into the pot at the poker game. For those at the end of a hand, they each have contributed a minimum of an equal percent based on the number of people in the hand. There were potentially 5 people at the start of the hand, and Will did not have enough to cover 20% of the final pot. He would have needed well over 200 years available, and we know he had a little over 100.
Other mistake: In Moriarty's college study, the white King and Queen chess pieces are actually on the wrong squares. Queen starts on her own color.
Other mistake: When David Norris is first trained in using the doors he is told to turn the handle clockwise yet one of the first doors he uses is a "push bar" door that can't be turned at all.
Other mistake: Hanna' grandmother, was shot in her head. But you don't see the bullet exit her head. When Hanna came into her grandmothers house, there was a bullet hole in the picture of her mother, which isn't possible.
Other mistake: Jill's shoulder seems to be perfectly fine when fighting with Sydney, even though she stabbed her shoulder earlier. (01:38:00 - 01:40:00)
Suggested correction: Anger and fear can be more than enough to gather enough strength to fight your way out of a difficult situation regardless of how much of a critical condition you are in.
Other mistake: Cataleya shoots a photo of the CIA agent with President Bush in his office through bulletproof glass. The window glass gets punctured and the glass of the photo frame breaks, but there is no bullet hole on the photo. (00:56:40)
Other mistake: When the conductor / ticket inspector is checking tickets, why doesn't he check Christina's?
Other mistake: Charge kicks down the door of the room Rickshaw is in, and is just a few feet away from him, directly in front of Rickshaw. It makes a very loud noise as the door breaks. Yet Rickshaw does not notice at all until Charge walks in a few steps. (01:09:50)
Other mistake: When priest is getting ready to leave the city we see him wrapping his hands in his black shirt but moments later when he pulls up his hood his hands are bare.
Other mistake: In the scene near the start as Will Atenton is being driven to his house by the property agent there is a close up of the car which shows a snow covered bonnet therefore the car would not have been driven very far as the engine was not warm.
Other mistake: When Eddie leaves his soon-to-be murdered friend's apartment, the apartment door automatically closes behind him. However, when Eddie returns, the door is ajar. It wouldn't be ajar if it were an automatically closing door.
Other mistake: When Schmidt sets the self-destruct timer at the Hydra base, the clocks count down at twice the speed of real-time.
Other mistake: Between the freeway battle scene and the convenience store scene; there's a transition shot where you can see the characters walking through a bombed out LA with the alien aircraft flying above. If you pay attention to them, instead of following the camera, at the end of the shot you will see them all stop moving mid-stride while everything else in the shot continues to move.
Other mistake: As Johnny looks down on the wrecked car after defeating the devil, we see a blank brake disk without a wheel on. I guess it would theoretically be possible for all five lug nuts to rip clean off during an accident and leave the brake disk bare and exposed. But then the threads in the disc would still contain the shorn-off remnants of the lug nuts, instead of being empty. (01:23:00)
Other mistake: A colleague approaches Ben, picks up a newspaper, and tries to pronounce Volkskrant. Ben gives the correct pronunciation, tells him it's a Dutch newspaper. However, the top of the newspaper is visible and says Trouw, a different Dutch newspaper. (00:40:00 - 00:43:00)
Other mistake: Succinylcholine paralyses you for about 10 minutes; in the movie it lasts way longer, and the bad guys were planning to use it instead of ropes and cuffs. It would have bought them a really short time, surely insufficient to make their planned escape to Mexico, while tying them up with just about anything (zip ties, scotch tape) would have given them potentially hours.
