Continuity mistake: After Dong-mae has been shot and has a flashback to a greeting he had with Ae-sin, there is a streak of blood shown coming out of his mouth going down to the bottom of his chin. The shot cuts to Hui-seong, but when it cuts back to Dong-mae, two additional (smaller) streaks of blood have suddenly appeared next to the first blood streak. (01:08:13)
Continuity mistake: When Ae-sin is practising her shooting skills, in a shot focusing on her, we can see her thumb is placed along the side of the rifle at a horizontal angle. When the shot cuts, her thumb is at a vertical angle. Then two shots after that, at a horizontal angle again. (00:58:33)
Continuity mistake: After Hina refused to use the drawing that Chun-sik and Il-sik made, when Il-sik says "If they parted young, it would be her mother", the ribbons used to tie his hat with are still. When the camera changes angles to focus on Chun-sik, where the ribbons are now blowing in the wind. Then when it cuts back to Il-sik, the ribbons are still again. (00:57:10)
Continuity mistake: Il-sik and Chun-sik approach Hina with some drawings they made for. Just as Hina says "I don't think I'll need this anymore", the two men look surprised. One of them has a ribbon (used to tie his hat with) on his shoulder. But in the next shot, the ribbon is off his shoulder. (00:56:20)
Continuity mistake: When the Japanese soldiers are arresting the English teacher and Nam-jong attempts to intervene, whilst one of the soldiers says "This American witch sold Japanese information to America", he is shown holding the strap for his rifle with his hand near his chest. When the camera changes angles, his hand is touching the bottom of the strap (near the butt of the rifle). (01:09:02)
Continuity mistake: When Eugene is about to shoot Wan-ik, after the flashback of Yong-ju saying "The one who killed Sang-wan and his wife was Lee Wan-ik", the scene cuts back to Wan-ik. In the shot, we can see his aid standing behind Wan-ik, to the right of him. The camera cuts to Eugene aiming, but when he fires in the next shot, the aid is now behind Wan-ik on his left. In the same shot, he ducks down, but in the following wide shot, he is standing upright. (00:12:00)
