City of Damnation (Korean: 유감스러운 도시; RR: Yoogamseureowoon dosi; MR: Yugamsŭrŏun tosi) is a 2009 South Korean action comedy film directed by Kim Dong-won and is a remake of the 2002 Hong Kong film Infernal Affairs.

After being noticed by his superiors, Choon-dong is assigned to go undercover to infiltrate a gangster network headed by Yang Kwang-seob.

Meanwhile, Lee Joong-dae (Jung Woong-in), a member of Kwang-seob's gang, goes undercover himself by joining the police force.

Joong-dae tries hard to gain favour with his squad leader and bureau director in an effort to expose Choon-dong's identity, but falls in love with a colleague, Cha Se-rin.

[3] On its opening weekend it was ranked third at the box office with 249,720 admissions,[4] and the film's disappointing performance was thought to illustrate a steady decline in the popularity of the gangster comedy genre with local audiences.
