Casual Person

Casual Person

Revealing mistake: When the Captain is tripped over by Ricky, his face lands on a plank of wood with nails sticking out of it. In the shot of his face getting impaled with the nails, we can see that the Captain has been replaced with a dummy. (00:08:50)

Casual Person

Continuity mistake: When the Captain slashes the elderly inmate's face with an object, the elderly inmate falls over and his left hand is covered in blood. Seconds later, just after the guard walks out of the room after asking what happened, a large amount of the blood on the elderly inmate's hand has disappeared. (00:08:17)

Casual Person

Continuity mistake: When the elderly inmate falls over after being hit with a wooden train, his glasses break off and land on the floor beside him. A few seconds later, when the bald inmate trips him over, the glasses have suddenly rotated 90°. (00:07:53)

Casual Person

Continuity mistake: When the elderly inmate has a wooden train smashed against his head, he is shown positioned in front of the bathroom sink. He then begins to stand up and charges towards the other inmates, and he is suddenly positioned much further back than where he was a few seconds earlier. (00:07:53)

Casual Person

Revealing mistake: When the elderly inmate is pushed over by the other prisoners, a wooden train he made falls out of his clothing. It can be noticed that the man is just holding the train in his hand whilst falling and drops it when he lands on the ground to make it appear as if it fell out of his clothing. He was not meant to be holding the train as it was not shown being held in his hand at any previous point. (00:07:25)

Casual Person

Continuity mistake: When the two prison guards discover that there is metal inside Ricky's chest, they begin pushing him over to the X-ray machine. The guard holding a baton is shown pushing the bottom of the baton against Ricky's upper back, but in the next shot, he's suddenly pressing the entirety of the baton against Ricky's back. (00:05:39)

Casual Person

Continuity mistake: When Ricky is being inspected for metal by the two prison guards, he opens his shirt so to reveal his chest. His right nipple (or left from the viewer's POV) is exposed, but in a close-up shot of his chest, the nipple is suddenly covered by his shirt. (00:05:28)

Casual Person

Visible crew/equipment: Just after the police bus pulls over inside the prison, the camera moves forwards towards the side of the bus towards the front whilst one of the guards goes to open the bus door. When the guard walks around the driver side just before reaching the door to open it for the prisoners, the reflection of the camera crew can be seen reflected on the side of the bus. (00:03:10)

Casual Person

Continuity mistake: When the infected Yon-suk turns into a zombie, he begins walking up to the surviving passengers and Seok-woo puts his hands out to try and stop him. On the side of the train is the K-RAIL logo. In one shot, Seok-woo and Yon-suk are standing beside the edge of the logo. Then in the next shot, the two are suddenly fighting towards the centre of the logo, and in the shot after that, they are fighting away from the logo. (01:42:21)

Casual Person

Continuity mistake: When Seok-woo, Su-an and Seong-kyeong have escaped East Daegu Station, just after Seok-woo climbs back onto the train after kicking the zombies off, Seong-kyeong is shown hugging Su-an, holding her hair with her left hand. When the shot cuts, Seong-kyeong is suddenly touching Su-an's upper back. (01:40:20)

Casual Person

Continuity mistake: When Seok-woo walks to the rear section of the train after getting infected, he rests his head the back of the train. There is a light shown on the back of the train located a foot away from his head. The camera cuts then to an angle closer to him and his head is suddenly much closer to the light. (01:46:31)

Casual Person

Continuity mistake: When zombie Yon-suk begins attacking Seong-kyeong, Seok-woo puts his hand over Yon-suk's mouth to get him off. His hand is directly over Yon-suk's mouth at first, but when Yon-suk begins to bite him, it is suddenly Seok-woo's thumb over his mouth. (01:43:18)

Casual Person

Continuity mistake: When Seok-woo is fighting zombie Yon-suk, Seok-woo starts to get pushed over the handrail. Yon-suk has his left hand on the handrail, but when the shot cuts, his left hand is suddenly on Seok-woo's shoulder. (01:42:35)

Casual Person

Continuity mistake: When the zombies begin attacking the passengers in Car 15, the primary characters are shown reacting in horror in the vestibule. The homeless man has his hands raised in the shot from behind them, but when the shot cuts, his hands are lowered. (01:20:05)

Casual Person

Continuity mistake: When the surviving passengers are getting off the train at East Daegu Station, just after Yong-guk jumps off, he extends his arms to help Jin-hee whilst she is jumping off the step. In the next shot, Yong-guk is suddenly looking around and walking and Jin-hee is walking as well. (01:29:25)

Casual Person

Other mistake: The time on Jin-hee's phone is 1:56PM when she gets a text from Yong-guk. But later on, when Yong-guk calls Jin-hee's phone and Yon-suk breaks it when attempting to get into the zombie-free car, the time is 3:31PM. Only a handful of minutes passed in between these scenes. There's no way over an hour and a half could have passed. (01:03:25 - 01:09:47)

Casual Person

Continuity mistake: Just after Jin-hee gets the text from Yong-guk saying they are coming back, she gets up from her seat to tell the train attendant. Whilst she is walking up to him, she has the phone in her right hand. She then says "My friend is walking up from another car" and points backwards with her right hand and the phone is no longer there, it is now in her left hand. (01:03:30)

Casual Person

Other mistake: When Jin-hee gets a text from Yong-guk saying that the people have been rescued and are heading back, the time is 1:56PM. This time is not possible given the events taken place prior. First, the train set off early in the morning, and every time a phone is shown after the outbreak starts, the time is always in the 7AM hour. For example, when Seok-woo is reading the texts from Kim, the time is 7:16AM and when he is on the phone to ask about the military being deployed in Daejeon, the time displayed is 7:20AM. The events of the movie after this point mostly play out in real time, with the only part being skimmed over was the remainder of the journey to Daejeon Station, so there is no way over six hours could have passed in between these two points. (01:03:25)

Casual Person

Continuity mistake: When discussing how to get through Car 11, Sang-hwa says "There's no way around it, let's go" and Seok-woo puts his arm over him, asks him for his phone and lowers his arm. At this moment, Seok-woo is shown kneeling about a foot away from Sang-hwa. When the shot cuts, Seok-woo and Sang-hwa are suddenly further apart from each other. (00:59:50)
