Factual error: When Eakins returns to the house after he swears an oath to the union. You can see a thermostat on the wall behind him. (01:40:00)
Other mistake: When Alice's ship is being chased, she orders her crew heel to port (turn left). Instead, it turns heel to starboard (right).
Factual error: The 2 C-class Mercedes Benz' they have in the CIA compound are the newer body styles that came out the year they were filming the movie. The Benghazi attack happened in 2012, the C-class had a different body style then.
Continuity mistake: When Alice leaves a party and is walking outside towards the Rockefeller Tree, she is wearing shoes with a chunky heel. When she goes inside the building with David, they show her walking towards the window and she has on shoes with a skinny heel. (00:59:15 - 01:01:30)
Audio problem: In the beginning, you can hear the sounds of the jungle, including the laugh of a kookaburra. The problem is: The film is set in India and kookaburras are only in Australia, not India.
Factual error: The villain performs his hit at the beginning of the movie by remotely changing the GPS destination of a cab, so they head to the wrong place and into an ambush. Assuming that neither the cabbie or Pope notice the change on screen, and that his sophisticated software silenced the voice announcement of the course being recalculated, and makes the new place also marked as the old one (it is after all a god-like movie software), the trick is done on on a London black cab, whose drivers are notorious for "The Knowledge", aka being required to learn the entire topografy of the city in one of the most demanding training courses in the world, and not using GPS. It'd be definitely unlikely for the cab driver to be totally unaware, to the point of Pope himself noticing first that they are at the wrong place.
Factual error: As the X-Men land in Cairo, scenes reveal the destruction Magneto is wreaking around the world, where it is simultaneously daylight in New York, Sydney and Cairo - it is possible for it to be daylight in two of these locations at once, but not all three. (01:46:00)
Continuity mistake: When Maddie is coming up with an ending to her novel, she opens one of the ending drafts. Not long after opening the draft, she decides to go on facetime and make a call, whilst the draft is still open, then the man she is trying to contact calls her back. She then closes the laptop and tidies up. When she returns and opens up the laptop, the draft that was just shown on the laptop has become a completely different one. (00:10:10 - 00:14:25)
Continuity mistake: The location of the FireBrand tower keeps changing throughout the film. 1:30 - the tower is in Lower Manhattan, south of the World Trade Center 2:55 - As Kevin Spacey lands, the tower has moved closer to the World Trade Center (side note - the shot immediately before this showed him falling towards midtown Manhattan, not the tower) 3:45 - the tower has moved further north towards midtown 4:50 - the tower appears to have moved back to the position it was in at 1:30. 5:25 - the tower has moved back to it's position at 3:45. 53:25 - We are given a view of the tower from their Central Park penthouse, and it has apparently moved much closer to Central Park (right next to One57 on the other side of Manhattan island) 56:45 - the tower has moved back down to its position at 3:45 and 5:25. 1:17:38 - I'm not entirely sure about this one, but you can briefly make out the two pools of the World Trade Center memorial, which would put the tower at its location at 2:55. 1:18:00 - the tower has moved to the exact location of One World Trade Center (therefore making that building disappear). 1:18:05 - the tower has moved back to its position at 2:55 (now One World Trade is visible).
Continuity mistake: When the church bell is rehung and struck, it goes from shoulder height to well above head height, then back to shoulder height in subsequent shots. (01:28:15)
Factual error: When Mike is being questioned, he calls himself a soldier. Marines always refer to themselves as Marines - soldiers are the army. (01:01:20)
Continuity mistake: Ben got his job. He has to see his wife though, and she passes him the divorce papers. The papers are in an envelope she slides across the table with the flap face down. It's face up in the reverse shot. (00:06:30)
Plot hole: Sang-hwa forces a zombie inside a toilet stall. The zombie begins to bang on the door violently and Sang-hwa has to hold onto the door in order to stop the zombie from getting out. However, it is revealed later on that the zombies do not attempt to attack the humans or react violently or aggressively if they cannot see them. If this is the case, then this scene of the zombie banging on the door even when it cannot see any of the uninfected humans contradicts the rules that are established later on. (00:25:48)
Continuity mistake: As Captain America arrives in his car at the airport car park, he stops right next to the line dividing the spots. In the following shot, when he steps out, the car is further away from the line, more towards the center of the spot. (01:26:50)
Factual error: The EMP burst would have only affected a small number of vehicles. Most vehicles act like a Faraday Cage.
Continuity mistake: When Batman goes to save Martha, he pulls the wooden box with his gun and throws it at one bad guy. The guy's head hits the wall, leaving blood. Later on, you still can see the dead guy but there is no blood on the wall any more. The blood appears again when Batman is about to finish off the last person who was stabbed and pinned against the wall. (02:17:30 - 02:18:35)
Other mistake: Duke is running through the city while dragging Max by his leash. A close-up shows Max being pulled between the bars of a metal fence, but the gap is much too small for Duke to have passed through.
Continuity mistake: When Nancy is surfboarding, she is going to ride her last wave for the day. When she is waiting for her last wave, the ocean appears to be calm, but when it cuts to the very far 3rd person view a big wave pops up on the screen. When it cuts back the wave has disappeared.
Other mistake: Just before Patricia Whitmore's plane (no. 107) is shot down, it is briefly shown with its number mirrored.
Continuity mistake: This is after the minotaurs have found Horus and Bek. As Horus is fighting the second to last minotaur, he breaks off both of its horns. In the next shot, only one horn is broken. (00:52:30)
