Trivia / I Saw the Devil

• What Could Have Been: Featured on the DVD/Blu-ray is a deleted extension to the ending. After breaking down due to realizing what he became in the process of getting his revenge against Kyung-chul, Soo-hyun is ordered by his bosses to disappear to China until things quiet down in Korea after what he did. Before he can go to his ferry, he notices a teenaged girl, who was seeing off her friends, disappear down an isolated escalator, with a suspicious, stalker-looking guy following her. After giving it some thought, Soo-hyun silently heads towards the escalator, hinting that, since he really has nothing left to live for and he didn't get enough satisfaction from his revenge on Kyung-chul, he's gonna look for more, accepting being the monster he became and presumably becoming an Pay Evil unto Evil-style vigilante.
