Continuity mistake: When Chun-sik and Il-sik find the stopwatch Hui-seong left for them to pay his rent with, the watch is shown being held against Il-sik's fingertips with his hand opened out. In the next shot, Il-sik's hand is suddenly clenched shut. (01:28:16)
Continuity mistake: When Il-sik finds the babushka doll, in the close-up shot, he is holding with two hands. When the shot cuts, he is holding it with one hand. (01:29:08)
Continuity mistake: When Hui-seong is burying the box of photos, whilst he is holding the shovel, we can see his left hand is positioned around a foot below the top of the shovel. A couple seconds later, when Nam-jong approaches him, there is a quick shot where we can see his left hand is suddenly touching the top of the shovel. (00:57:00)
Continuity mistake: In the flashback of Eugene leaving the photo studio in Tokyo, he is holding a photo of him and Ae-sin. In the close-up shot of the photo, his right hand is shown placed along the side of the photo, towards the middle. When the camera cuts back to him, his right hand is suddenly placed at the bottom of the photo. (01:30:50)
Continuity mistake: When Dong-mae is lying on the ground and about to die, there in an extreme close-up of his right eye (shown from the side), where we can see a bloodied tear next to his eye. This bloodied tear cannot be seen in any other shot of his face. (00:44:55)
Continuity mistake: After Hui-seong takes the photos of all the officials, the scene cuts to the dead guy lying on the floor. There is a small puddle of blood forming on the floor. When the shot cuts to reveal Eugene is in the room, the puddle of blood is much bigger. (00:02:15)
Continuity mistake: Eugene finds the list of Righteous Army members, folds it up and puts it in his jacket pocket. In the shot of him putting the list in his pocket, both his left hand (holding onto the jacket) and his right hand (putting the list into his pocket) are level with each other. In the next shot, someone walks into the room and his hands don't change position. When the shot cuts back to Eugene, his left hand is much lower down than the right. (00:02:25)
