Continuity mistake: When Eugene is hiding inside the rickshaw after being rescued by the rebels, just as he says "She's injured", he is shown holding a gun, but his fingers are not placed on the magazine. When it cuts to a closer shot of him, his fingers are suddenly placed over the magazine. (00:17:14)
Continuity mistake: When the general is pointing his gun at Deok-mun after realising that he was lying about the rebel they found being deaf-mute, just as Deok-mun says "He's willing to tell us everything", his left hand is pointing left towards the rebel on the ground. In the next shot, his hand is raised to be level with his chin. Then in the shot after that, his left hand is lowered. (01:12:33)
Continuity mistake: When the general shoots the elderly rebel, there is a huge blood stain left on his clothes where the left-hand side of his upper chest is located. When he collapses on the ground in the next shot, the blood stain has suddenly disappeared from his clothing. (01:13:23)
Continuity mistake: When Mr. Haengrang and Ms. Haman are walking through the village, just as Ms. Haman says "That's the only thing that bothers me", one of the ribbons used to tie Haengrang's hat can be seen lightly blowing in the wind. In the next shot, the ribbon is completely still. (01:13:42)
Revealing mistake: After Mr. Haengrang and Ms. Haman are shot by the Japanese soldiers, there are visible blood stains on their clothing from the wounds they would have sustained. But there are no bullet holes shown on the blooded part of their clothing, which is where the bullets would have hit. (01:17:49)
Continuity mistake: When Mr. Haengrang starts to collapse after getting shot, a blood stain can be seen beginning to form on one side of his chest. Three shots after this, two tiny drops of blood have suddenly appeared on his shoulder and upper sleeve (on the opposite side of his chest) that were not there a few seconds earlier. (01:17:49)
Revealing mistake: When Ms. Haman is shot by the soldiers, the moment that the gunshot that hits her is heard, and she is shot, there is already a massive, thick blood stain on her dress from where she is bleeding from. No gunshot wound on the planet can create an amount of blood that massive or thick in an instant. The blood stain was likely applied to her dress before filming the shot. (01:17:52)
Other mistake: When Mr. Haengrang is lying on the ground after being shot, there are tiny drops of blood visible on his face, presumably blood splatter after getting shot. However, when he was shot just seconds earlier, all the gunshot wounds he received remained inside his clothing and there was no blood splatter of any kind shown, so there is no way any blood could have splattered on his face. (01:18:30)
Other mistake: After Haengrang and Haman have succumbed to their wounds and died, a puddle of blood can be seen in between the two of them. The problem is, this puddle of blood doesn't appear to be emerging from anywhere. The blood shown on the ground would have come from their wounds (and would have formed the puddle of blood), but the puddle isn't connected to either of their bodies. (01:19:40)
