Trivia, insights & behind the scenes
The title 'Doubt' refers to both Tae-su's professional methodology and his crumbling certainty about his own family—rare Korean drama where Korean police procedural tropes get emotionally weaponized.
Han Suk-kyu reportedly requested multiple script revisions to ensure Tae-su's despair felt earned rather than melodramatic—his 40-year career peak performance according to Korean critics.
