Continuity mistake: After Man-seob returns to Gwangju, whilst he and Jurgen are walking through the city, Jurgen is filming the citizens in despair with his camera. In one shot, the camera is raised so that it is level with his eye. When the shot cuts, the camera is suddenly lowered.
Continuity mistake: Man-seob smears some cream above his upper lip after a few smoke grenades are deployed. The amount of cream shown over his upper lip changes between shots.
