Plot

The film is set on a stretch of the east coast near the border, where a marine platoon guards a barbed-wire fence against North Korean infiltration. A sign warns that anyone entering after 7 p.m. may be shot as a suspected spy¹. Private Kang (강상병), obsessed with catching a spy and decorated for his zeal, trains obsessively while his fellow draftees wait out their service³^•⁹.

One night, through his night-vision goggles, Kang spots a couple who have entered the restricted zone to make love while drunk. Terrified by the sight of the man's bluish back, he opens fire, and the body of the young man, Yeong-gil, is torn apart by gunfire and a hand grenade¹. Kang's commanding officers, to avoid responsibility for the civilian death, award him leave "for catching a spy"⁵.

On leave, Kang confesses to his girlfriend that he killed a civilian; she calls him a murderer⁵. His behavior grows increasingly violent, and the army discharges him on psychiatric grounds (의가사 제대)¹. He refuses to accept the discharge, returns to the base like a "phantom," steals ammunition and a uniform, and attacks his former comrades². Meanwhile Mi-yeong, who watched her lover die, loses her mind and wanders the fence line; the two broken figures together plunge the coast into a spiral of violence¹. In the film's closing movement, every soldier wears night-vision goggles, and the green vision makes the insane soldier indistinguishable from the sane ones¹⁰.

Production

Kim Ki-duk drew the story from his own military memory. He had served as a marine on coastal guard duty, and in his director's statement he recalled a fellow marine who trained obsessively for infiltration missions, asking where such a man would spend his stored-up violence afterward³.

The production had planned to film at the east-coast marine post where Kim had actually served, but the Marine Corps refused cooperation and opposed the film, so a set was built instead on Wi Island in Buan County, North Jeolla Province, at a reported cost of about 200 million won¹¹. The film was produced by LJ Film, with Lee Seung-jae as producer, Baek Dong-hyun as director of photography, and Kim Sun-min as editor¹^•².

Casting drew attention because Jang Dong-gun, then a top star, chose to appear in the film of a director known for controversy; the trade press reported that he decided to take the role of his own accord³.

Release and reception

The Coast Guard premiered as the opening film of the 7th Busan International Film Festival on November 14, 2002, in world premiere⁴. At the festival's opening, Kim said he had wanted to convey the situation of the Korean peninsula, and that whether the film was entertaining was the audience's concern rather than his⁴. Ticket demand set a festival record: the opening film sold out in 2 minutes 4 seconds, a record that stood until 2008¹².

In 2003 the film screened in the Official Selection, Competition at the Karlovy Vary International Film Festival and in the Asian New Classics section of AFI FEST²^•¹³. It was later shown in a Kim Ki-duk retrospective at the Florence Korea Film Fest in 2005⁶.

Domestic reception was contentious. When it opened in November 2002, groups of discharged soldiers attended theaters together and the film became the subject of social debate⁸. Box office figures differ by source: Cine21 records 123,633 admissions, while the Korean Cinematheque describes about 300,000 admissions, a comparatively high result among Kim's films¹^•⁸. Kinoafisha lists a worldwide gross of $2,442,863⁷.

Themes and style

Kim had built his career on examining violence in Korean society, and The Coast Guard turns that examination on the military itself³. Critics read the film as an allegory of the division of Korea: rather than the land border, it takes the coastal fence as its setting, and the gun turns not toward the enemy beyond the wire but toward people inside it⁸^•². The Karlovy Vary synopsis calls it "a rough allegory about the causes and consequences of Korea's division," highlighted by surreal elements².

The Korean Cinematheque's retrospective note describes Kang's mental collapse as more than a depiction of post-traumatic stress, reading it as the tragedy of an individual trapped in the machinery of state violence, and reads the repeated "bat unit" training rituals as performances of how the army dehumanizes the individual⁸. The same note points to the scene in which Kang receives a commendation for the killing as exposing the state's habit of repackaging murder as heroism⁸.

Scholarly writing has placed the film alongside Kim's Address Unknown (2001) as two works about Korean unification and the psychological cost of maintaining a permanent military consciousness, portraying anticommunism and militarism as structural causes of personal and social disintegration¹⁴. Compared with the poetic and fantasy metaphors Kim often used, the film is noted for a more direct style; Cine21's festival report records that it was called the most hard-boiled of Kim's films³.
