Factual error: In the first scene where Dr Strange is preparing for surgery he uses improper surgical gowning technique breaking aseptic protocols. Strange puts on a mask after washing his hands, contaminating his clean hands by bringing them in proximity to the non-sterile environment of his face. Surgical masks must be worn before the full washing of hands. Another error is that he inserted his hands all the way through his gown to don gloves. Hands must never leave the sleeves and gloves must be put on with the sleeves still covering.
Factual error: A theater marquee is visible promoting the showing of a film called Tribeca Follies. The acronym "Tribeca" - an amalgamation of "Triangle Below Canal [Street]" - didn't come into usage until the 1970s.
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)
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.
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 license plate of the car that takes the protagonist to the sanitarium is GR 36E46. That's not a valid Swiss plate: GR indicates the canton of Graubünden, but other than that it is supposed to have only digits and no letters.
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 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)
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)
Continuity mistake: At breakfast in the BFG cave the bottle of frobscottle is taken from the table by the big bad giant when he says "I is taking this", only to show up again when Sophie clambers out the shnozcumber.
Plot hole: After escaping from execution, the assassins still made use of throwing knives out of their garments as they ran through the city. These would have been removed from them before they were shackled in the cell.
Other mistake: When the children arrive in Blackpool, Emma tells Jake that loop entrances can be anywhere and that "the one in London is in a subway tunnel", but on the map of all the loops they were viewing previously inside the boat, there was no marking of a loop in London.
Visible crew/equipment: In the beginning where Amanda Waller is talking in a restaurant. While the camera focuses on her towards the end of the scene, they move the camera right, facing towards her left side of her face. Watch the wine glass, you'll see the crew moving along with the camera.
Continuity mistake: When they are in the big hall he goes to demonstrate that he can shoot. He shoots 5 arrows. When you see the arrows hit the bowl only three hit. (00:32:00)
Sometimes he shoots 2 at a time. He does shoot 3 times, but he shoots five arrows.
The correction is valid. He never shoots 2 arrows at once. You may need to watch in slow motion if you can't see what happened. He grabs 3 arrows with his right hand and keeps them in his hand as he shoots 1 arrow at a time. This is probably most obvious on the 2nd shot where you see the 2 arrows in the bow, but when he releases his hand, you see one arrow still in his right hand and 1 arrow leaving the bow.
He starts holding all 3 arrows, shoots 1, reloads holding 2, shoots 1, then reloads and shoots the last arrow.
Revealing mistake: In the opening scenes, we see a very pregnant Draka reclining on a bed of animal hides as Durotan watches over her. In the extreme closeup, we see Draka twitch her lips, and her small tusks flex from side-to-side with her lips, instead of remaining firmly aligned with her jaw as they should.
Continuity mistake: The sun angle changes several times during the chase sequence when the dragon is on the flatbed truck.
Revealing mistake: Right after the little girl sprays the monster with bug spray, you can see the costume of the monster, it's wearing a black cap. (01:19:00)
Continuity mistake: At the beginning of the movie, the hunter is looking for his dog. The rifle on his shoulder keeps changing position, being upside down or not - which is easy to spot because of the big scope. (00:01:30)
