Plot and setting

The story takes place in 1808, in the late Joseon dynasty, on Donghwado, a remote island whose economy rests on paper manufacturing. A cargo of paper destined as tribute for the royal court burns aboard its transport ship, and the investigator Won-kyu is dispatched from the capital with a team to solve the fire.²^•⁴ On the team's first day on the island, a savage murder occurs, and further killings follow.⁴

Unable to identify a culprit, and hearing rumors that a rain of blood (혈우) has fallen, the villagers begin to waver: they believe the murders are the work of the vengeful spirit of Kang Gaek-ju, a man whose entire family was beheaded seven years earlier.⁴ The English-language synopsis frames the period as "an era of loathing and vengeance towards Catholics," and the man put to death had been executed for practicing Catholicism.⁷^•⁸ As Won-kyu investigates with cold, scientific methods, he clashes with In-kwon, the coercive son of the paper-mill owner, and the inquiry exposes a conspiracy hidden behind the curse.⁴^•⁹

The Busan International Film Festival's program note describes the film as a serial-killer genre piece, recalling Seven, fused with a historical drama and a melodrama, and notes that its murderer is not a killer fascinated by the act itself but a victim of the political circumstances of the time, robbed of a lover by another's will.²

Historical themes

Korean critics read the film as an examination of the collision between medieval barbarity and modern civilization in late Joseon. A Kyunghyang Shinmun analysis placed the 1808 setting between King Jeongjo's sudden death in 1800 and the Hong Gyeong-rae rebellion of 1811, a period in which a royal in-law family monopolized power through sedo politics and reformers were purged under the label of "Western learners" (서학자), that is, Catholics, while modern science such as the weight-lifting crane used to build Hwaseong Fortress was advancing.¹⁰ The film's critic Hwang Jin-mi connected its themes of class-system critique, the fight against superstition, and free love to the early-20th-century sinsoseol (new novel) genre, pointing out that the film takes its very name from the sinsoseol novella Blood Rain (혈의 누), one of that genre's principal works.¹¹^•¹²

The film is also one of the most violent Korean films of its period. The Korean Film Council's retrospective notes that carefully staged scenes of carnage, such as an execution by drawing and quartering, retained their power to shock twelve years after the premiere, and that the film uses the tropes of an investigation to exhume a social hierarchy that dictates its characters' actions.⁸ The 18+ rating was attributed to these brutal scenes.¹³ In an interview, director Kim described the film as being about "the sense of shame," which he saw as disappearing from Korean society.¹⁴

Production

Producer Kim Seong-je approached Kim Dai-seung with the project under the tentative title 혈우, from which the English title derives. Kim had not previously worked in historical drama; his first film had been the melodrama Bungee Jumping of Their Own (2001).³ Period dramas were generally avoided by directors at the time because of high budgets, difficult shoots, scarce locations, and dialogue that burdened actors.³ The film entered pre-production three years before its release.³

Shooting began with a crank-in on June 28, 2004 and ended with a crank-up on February 28, 2005 at the paper-mill set in Yeosu, after about 95 shooting days across roughly eight months. Two large sets were built, and a village festival scene used more than 400 extras. Weather worked against the crew, with typhoons and heat in summer and cold in winter, and lead actor Cha Seung-won suffered a fall from a horse, so that the effective shooting period was five to six months.¹⁵ KBS notes the picturesque provincial locations of Yeosu, Boseong, and Gyeongju.¹⁶

The key crew included cinematographer Choi Young-hwan, composer Cho Young-wook, editor Kim Sang-bum, art director Min Eon-ok, lighting director Kim Seong-gwan, and costume designer Jeong Gyeong-hui.¹ Production companies were Sidus Corporation and Good Movie, with distribution by Cinema Service and international sales by CJ Entertainment.¹^•⁷

Reception and awards

The film opened on 264 screens and, by the Korean Film Council figure, sold 1,926,592 admissions for a gross of 12,367,486,506 won, ranking 17th among 2005 releases; Cine21's page records 2,274,995 admissions, and a Kyunghyang report placed it fourth in first-half 2005 attendance with 2.27 million viewers.⁵^•⁴^•¹⁷ Cine21's four critics gave it scores between 6 and 9, averaging 7.50, with an audience score of 7.91.⁴

Awards. At the 26th Blue Dragon Awards in November 2005, Shin Jae-ho won the Technical Award for special makeup, and the film was nominated for Best Film, Best Director, Best Cinematography, and Best Supporting Actor (Park Yong-woo).⁶^•¹⁸ It won Best Film at the 2006 Baeksang Arts Awards and took the Chunsa International Film Festival's 2005 awards for Best Film, Best Director, Best Supporting Actor, Best Editing, Best Cinematography, and Best Lighting, along with Grand Bell Awards for Best Art Direction and Best Costume Design and Korean Film Awards for art direction, sound, and visual effects.¹ The Korean Association of Film Critics gave it Best Screenplay, Best Cinematography, and a Technical Award in 2005.⁷^•⁶ It also screened at international festivals including Yubari International Fantastic Film Festival (Young Fantastic Grand Prize), Seattle, Fantasia, the New York Asian Film Festival, and Sitges.⁷^•¹

Critical opinion divided on the film's structure. A Seoul Shinmun review praised its visuals and sound as far superior to conventional period films and Cha Seung-won's dense performance, but found that dramatic tension dropped sharply in the second half and that revealing the culprit through the investigator's mouth was a lazy device.⁹ Movie fans cited by KBS say it is one of the few Korean thrillers better understood on repeated viewings.¹⁶

Place in Korean cinema

The Korean Film Council's retrospective places Blood Rain among the films that carried Korean cinema's momentum after Oldboy's 2004 Cannes triumph, alongside A Bittersweet Life (2005) and The King and the Clown (2005), at a time when period dramas were still a risky genre at the box office.¹⁹^•⁸ Scholarly work on Korean historical film reads it, together with Shadows in the Palace, as using horror-genre tropes to represent systematic violence in Korea's history and the pain of remembering a traumatic past.¹⁴
