Continuity mistake: Whilst Jung-seok is driving with his family on the first day of the zombie outbreak, after he says "All other roads must be blocked", his sister looks to the left to face her son in the back seat. The shot then cuts to focus on Jung-seok, and the sister can now be seen looking straight forwards out the window. (00:01:45)
Continuity mistake: When Jung-seok is on the boat with his family, a soldier walks into the cabin he is staying in. When this happens, Jung-seok is shown stroking the back of his nephew's head, down to the back of his neck. The camera changes to a different angle and his hand is suddenly still and motionless. (00:04:33)
Continuity mistake: When Jung-seok returns to the cabin after the zombie outbreak has started in it, there is a shot of him walking past a support pole. The next shot is a POV angle of Jung-seok walking through the cabin. The following shot then shows Jung-seok walking past the same pole a second time. (00:07:08)
Continuity mistake: When one of the restaurant patrons starts shouting at Chul-min, he attempts to walk over to the patron, so Jung-seok tries to hold him. In one angle, Chul-min has his left hand placed near the middle of Jung-seok's torso. When it cuts to an angle with Chul-min's back to camera, we cannot see specifically where his hand is placed, but the distance between his body and Jung-seok's body indicates that it is too far for his left hand to be positioned on Jung-seok's torso in the same place as in the previous shot. (00:16:06)
Continuity mistake: Chul-min tries to have a fight with one of the restaurant patrons whilst Jung-seok restrains him. Whilst the patron is saying "Do you even care about other patrons", Chul-min has his right hand on Jung-seok's upper arm, but when the shot cuts, the hand is no longer there. (00:16:07)
Continuity mistake: Just after arriving in the Korean Peninsula, the group is shown walking across an abandoned road. There is a shot where Jung-seok has his rifle raised so that he can look through the eyepiece and is then shown lowering it. Then it cuts to an overview shot where the rifle is suddenly raised to Jung-seok's eye again and then lowers it once again. (00:19:52)
Continuity mistake: Once the group find the truck with the money inside, the man in the driver seat awakens as a zombie and begins attacking Chul-min. This prompts Jung-seok to pull him out of the truck and shoot the zombie. Right before he shoots the zombie, there is a quick shot where Chul-min is standing beside Jung-seok. The shot then cuts to the zombie getting shot and Chul-min is standing behind Jung-seok. (00:27:06)
Continuity mistake: Sergeant Hwang is thrown a javelin to stab one of the team members who assisted in getting the money. When he catches the javelin, his hand is placed over some tape that has been wrapped around it. The camera cuts to a different angle where his hand is now placed slightly above the tape. Then two shots after, his hand is positioned much further up the javelin. (00:39:03)
Continuity mistake: When the 3rd platoon returns to the hideout, just as Sergeant Hwang says "Private Kim! Isn't it beautiful?", he is standing next to a tall soldier with long hair that is tied back. The shot changes to a different angle and the sergeant is now standing a foot or two ahead of the tall soldier. (00:43:31)
Continuity mistake: When Chul-min is being cornered by the other soldiers at the compound, a man walks up to him with a knife to cut his shirt off. In one shot, the knife is being pointed at a diagonal, but slightly upward position. In the next shot, he is holding the knife in an entirely vertical position. (00:50:02)
Continuity mistake: Chul-min gets the number 61 spray painted on his torso and back, at the compound. When the soldiers begin taking him to the shipping container to lock him in, the number 6 on his torso is smudged. A minute later, when the inmates begin going into the zombie pit, the 6 on his torso is no longer has the smudging shown earlier. (00:50:55 - 00:52:15)
Continuity mistake: When Min-jung is about to get out of the car, she asks her daughter to hug her. In one shot, her right hand is at a rotated angle, but in the next shot, her right hand is suddenly at a straight angle. (01:05:04)
Continuity mistake: Captain Seo walks into a room to find Sergeant Hwang looking at bottle of gin. Just after Hwang says "Johnny Walker Black Label", he turns his head away from the bottle, looks forwards, then begins to turn his head to the left to face Seo. In the next shot, Hwang is still looking at the bottle, before turning to face Seo. (01:10:00)
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)
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)
