Casual Person

Visible crew/equipment: When Yun-ji hears the sound of a barking dog coming from outside the apartment, he runs outside, then runs down the hallway and stops to look over a small wall once he sees where the barking is coming from. When the camera pans around him, just before it is revealed which dog was barking, the shadow of the camera can be seen briefly cast on his upper back. (00:25:35)

Casual Person

Stupidity: When the overlord confronts Joan, he summons hundreds of demons to make sure that she is cornered and can't get away. However, the demons only appear to approach Joan from behind and from the side. After she kills the overlord, there is an entire area in front of Joan (behind where the overlord was standing) that is completely free of demons that she is able to run towards and escape. If the overlord was intent on cornering her, he should have made sure that all surrounding areas were covered.

Casual Person

Stupidity: Whilst the chaplain and one of the marines are talking in the kitchen, a demon sneaks up behind the marine, stabs him through the back and kills him. The demon then walks up to the chaplain and strikes him across the face and leaves the room to search for the rest of the crew. Despite the intent being to kill the crew, the demon does not make sure that the chaplain is dead before leaving. It just assumes the strike across the face will be enough to kill him.

Casual Person

Stupidity: When Joan and Winslow are walking through Level 2 after the monsters begin attacking them, at one point Joan turns around and shoots at a monster, but she misses and the monster is able to hide. After this she turns back around and continues to walk down the corridor. The monster she shot at isn't dead, it's just hiding, but instead of going to inspect where it ran off too, she decides to walk in the opposite direction, putting herself at risk of the monster sneaking up behind and attacking her.

Casual Person

Stupidity: Just after Joan finds Winslow after he kills a monster, they discover that it was actually a human geneticist, Dr John Carmack, that transformed into a monster, and they realise this by checking his name tag. Even if they didn't know the extent of what happened in the compound beforehand, the monster was still wearing human clothing and its body was still in the shape of a human body, so they should have, at least, realised that it was originally a human, even before looking at the name tag.

Casual Person

Stupidity: When Winslow sees Tarek getting eaten by one of the monsters, he runs up to the monster and attempts to tackle him. Apparently, he just forgot that he was holding a machine gun and could have easily just shot the monster instead of trying to stop him by hand.

Casual Person

Stupidity: When the marines are searching through Level 2 and detect lifeforms, they are about to shoot, which prompts a surviving scientist to run out into the open shouting "Don't shoot! Don't shoot!" This was a very foolish way of trying to get them to not shoot. Running out into the open like that could have prompted the marines to just start shooting out of shock or instinct even if she was going to say not to.

Casual Person

Stupidity: Once the marines have climbed down into Phobos compound, and have entered through the airlock door, they check the control gauge to see if the O2 levels are good. They were aware this was something that needed to be checked, but they brought no protective equipment with them in case the air was unsuitable to breathe.

Casual Person

Stupidity: The marines all wear helmets as part of their protective gear when they go into the Phobos compound, but Bennett and Akua do not wear any helmets at all. They wear bullet proof vests and arm themselves with weapons, but unlike the other marines, they go in without any way of protecting their heads.

Casual Person

Continuity mistake: When Adrian's throat gets slit, he is shown clutching his neck with his hand, then falls from the chair he is sitting on and collapses onto the floor. He is also shown banging his hand on the table whilst he falls over. This same moment is then shown again on the CCTV camera, but here, he is shown falling from the chair and collapsing onto the floor, all while clutching onto his neck the entire time. The moment where he bangs his hand on the table is not shown.

Casual Person

Factual error: The opening scene shows Cassie and Bryan booking their holiday on a laptop. The dates that they book the holiday home are between May 5th 2018 and May 12th 2018, which means the movie is set in 2018. But later in the movie, when Cassie finds the video of Bryan with the two women on his phone, the date is listed as "Sunday, May 7", and May 7th 2018 was a Monday, not a Sunday. (00:01:05 - 01:10:55)

Casual Person

Character mistake: The letter from the FBI containing the results of the blood and semen test is filled with numerous typos. First, on the line "Subject: Result of examination requested", the word "examination" is misspelled "examnation." Second, the term "DNA instrumental analyses" has "instrumental" incorrectly spelled as "insrumental." Third, the line "Reference: Letter dated October 21, 1987", has the word "dated" misspelled as "dateed" and the month "October" misspelled as "Octorber." (01:58:35)

Casual Person

Visible crew/equipment: Whilst Dignan is leaving the motel, Inez gets Rocky to say to Dignan "Tell Anthony, I love him", to which Dignan says "All right, man, okay" and walks off. The following shot after this is of Dignan walking past the side of a building. Right at the start of the shot, for a split second, the reflection of the cameraman can be seen reflected in the window beside him. (00:48:45)

Casual Person

Continuity mistake: When Cecilia and Adrian are speaking at the dinner table towards the end, after Adrian says "I would burn everything I own just to prove that to you", Cecilia says "okay" and Adrian also replies with "okay." At this moment, Adrian's hands are placed on the table. In the next shot, Adrian's hands are suddenly raised slightly, above the table.

Casual Person

Continuity mistake: When the investigator begins confessing to the other police officers, one of them has him eat a handful of salt. After eating the salt, tiny salt grains can be seen on his lip, and can be seen on his lip for the following minute whilst he is trying to convince them he was the killer. When he says "But I left fingerprints all over her apartment", a larger amount of salt can be seen on his upper chin that wasn't there a minute earlier. (01:45:52 - 01:46:57)

Casual Person

Continuity mistake: After speaking with the plumber at the Homicide Decision, the investigator and a colleague begin walking down a hallway and the colleague puts his hand on the investigator's arm. When this happens, the investigator has a small cup of espresso raised up to his face. When the camera changes angles, the small cup of espresso is suddenly lowered away from his face. (01:23:15)

Casual Person

Other mistake: At the docks, when Min-jung is inside the truck that is surrounded by zombies, there is a moment shown from inside the truck where the helicopter is shown in the background. The helicopter is far off in the distance, but when Min-jung begins to put the machine gun under her chin to shoot herself with, Jung-seok and Min-jung's daughters (who are standing right next to the helicopter) can see exactly what Min-jung is doing inside the truck, even though it should be too far away for her to see what is going on. (01:45:13 - 01:45:39)

Casual Person

Continuity mistake: After seeing the helicopter that her father called for, Min-jung reaches for a machine gun that is lying on the ground, using her right hand. When the shot cuts, she is using her left hand. (01:42:51)

Casual Person

Factual error: When Chul-min is shot by Sergeant Hwang, it takes only a couple of seconds for him to die. The bullet hit Chul-min on the left-hand side of his upper chest and was only shot once. No human being on the planet can die from a single bullet wound to the chest that quickly. It would have taken a couple of minutes, maybe even longer, for him to die from that. (01:20:35)

Casual Person

Continuity mistake: After Jung-seok runs into the hideout, it cuts to Sergeant Hwang inside the zombie pit shouting "Number 61", where he pushes a button to release zombies into the pit. In the first shot of Hwang, there is a man beside him who has his elbow resting against a handrail and has his lower arm positioned behind the edge of the handrail. In the next shot, the same man now has his lower arm positioned over the edge of the handrail. (01:15:55)
