Stupidity: The building is supposed to be without power - at all since the generator has been destroyed - and life support machines are not powered up, but the 3D printers in every room are powered up - so that the good guy can squish the bad guy's head in it, and the elevators, so that the good guys can escape. What sort of hospital has its electric grid rigged in a way that the elevators keep working but critical surgical equipment goes dead the moment the power fails? (01:12:00)

Morgan: I need to say something to you, okay? You couldn't have changed anything, and none of that was your fault.
The Nurse: You got kids, Mo?
Morgan: Yeah, I got two.
The Nurse: Then you know. It's always your fault. (01:01:20)

Trivia: After the 'Produced by' in the credits, there's a brief sequence hinting at Nice being still alive - since someone with her hairstyle darts by.

Character mistake: At the beginning of the movie you can read the rules of the premises, in particular rule number 3 says; "No guns or any type of weapon permitted through the gates." However, the Wolf King's cronies dump their guns before the gate even when they were never supposed to be able to come in (so does Burke at the beginning, but he was trying to be admitted in). (00:07:15)

Trivia: Besides a passing reference to 'the wall' to Mexico, there's a more subtle reference to a certain US President in the brand of the generator activated 20 minutes in and at the end of the movie; it's "ковфефе", which is a possible transliteration in Cyrillic of the infamous Trumpian typo "covfefe." (00:21:30)

Continuity mistake: Nice draws a line in the asphalt of the secret passage (cool idea, although there's no way that the bad guys can actually see that especially at a distance!). In the first overhead shot, there's a gap in the line. When the line is shown again next with the first baddie croaking before it, the line has already changed. (01:15:45)

Continuity mistake: When Bautista confronts the thugs still to the other side of the gate saying "Visiting hours are NEVER!", Crosby is holding two consecutive horizontal bars in one shot, two with one bar apart in the next. (01:15:30)

Continuity mistake: Nice's hands invert position (left up, right up) when she is hugging/supporting Waikiki after he jammed the printer. A moment later she supports him with her left hand on his bicep, but it is gone in the reverse shot. (01:12:25)

Sammo ★

Plot hole: Waikiki is not supposed to know who 'Niagara' is and most importantly, he is supposed to think that the Wolfking and his men are there for him and Honolulu. Yet the moment the Nurse mentions that Nice is "with Niagara", his reaction is as if he always knew the Wolf King is a patient. (01:10:00)

Factual error: Sherman prints a gun through the hospital's 3D printer. We see the gun, the cylinder, and 6 bullets. But if bullets are printed too, they still would need to contain the gunpowder, and the 3D printer construct shown there looks made out of a single kind of material, plain looking, surely not the product of a wonder machine that'd be able to recreate the complex chemistry required to make working bullets it was not even designed to do - in fact they look like suppositories, with no division at all between primer, casing, etc.

Sammo ★

Other mistake: In the close-up of the gun freshly printed, there's a bunch of molten plastic by the gun cylinder and the grip. Waikiki retrieves it right away, bare handed, and the bed is completely clean too. (01:03:25)

Sammo ★

Revealing mistake: Gone past Waikiki who tells him he knows about the cop, Everest wheels her to the secret door. Batista to open it touches the leftmost corner of the slat. In previous close-ups, the button was at much greater distance from the wall, surely not just an inch. He's pushing no button, just pretends to. (00:56:30)

Sammo ★

Revealing mistake: When the Wolf King is arriving through the elevator, there's a shot from a distance featuring Jodie Foster that wheels a chair in. You can see in it that the elevator arrow display is not moving; nobody is using them. (00:50:35)

Sammo ★

Continuity mistake: After the successful surgery on the policewoman, Nurse goes out of the room and leans against the wall, her hand trembling. In the two shots, the left ear bud of her walkman is on opposite sides of the microphone. (00:45:25)

Sammo ★

Continuity mistake: The Nurse fixed the policewoman, and they had a chat. When she leaves saying she has to prep for Niagara and that "Everest will walk you through the aftercare", Batista crosses the arms he had already crossed in the previous shot. (00:45:15)

Sammo ★

Continuity mistake: The Nurse asks Everest to pass her the microwave scalpel. During the scene, when she daydreams about her son's death, the earplug changes position and gets on her lapel during a cut. (00:40:00)

Sammo ★

Continuity mistake: Nice walks away from the bar after she told Waikiki to run away. There's a close-up of Sterling K. Brown looking at the pen while the bottle of bourbon is in the foreground; the bottle is fuller than it is in the rest of the scene, where just barely the bottom is left. (00:39:20)

Sammo ★

Continuity mistake: When Nice opens the pen-shaped safe, she holds it by the very bottom as it unlocks and extends, but her hand is back in a position next to the rim in the next shot. (00:38:05)

Sammo ★

Continuity mistake: When the Wolf King's crony "double taps" the cops that Batista roughed up, the footage shows a strong projected light that was nowhere to be seen in the alley - even assuming the footage heightens the luminosity, it is not even consistent with how the footage from that security camera looked earlier. (00:33:55)

Sammo ★

Continuity mistake: Batista knocks out of the three cops; the one that is lying further down the street is lying down at distance from the wall and oblique to the street's direction. In the overhead shot when the two staffers get back to the hotel, that cop is tucked in close to the wall. (00:32:55)
