Plot and historical setting

In 1636, the fourteenth year of King Injo's reign, the Qing dynasty invades Joseon. The court had planned to take refuge on Ganghwa Island as it had in the earlier Manchu invasion of 1627, but the Qing vanguard moved south so quickly that the king and his ministers instead entered the mountain fortress of Namhansanseong, where they were completely surrounded.²^•⁷

The film's dramatic engine is the conflict between two ministers. Choi Myung-kil, Minister of Interior, argues for negotiating with the Qing, holding that even a humiliating submission could preserve the country and its people; Kim Sang-heon, Minister of Rites, insists they fight to the end rather than kneel to what he regards as barbarians.²^•⁸ King Injo, unable to decide, wavers between them as cold, hunger, and overwhelming military inferiority take hold and the Qing demands grow harsher.⁹ Meanwhile the Qing emperor arrives at Samjeondo, and Injo ultimately surrenders, performing the ritual submission known in Korean history as the humiliation of Samjeondo.¹⁰

The siege the film depicts lasted 47 days, from December 1, 1636 to January 30, 1637.⁴

Production

Hwang Dong-hyuk, whose earlier films were My Father (2007), Silenced (2011), and Miss Granny (2014), said he was drawn to the project after reading Kim Hoon's novel and learning what happened inside and around the fortress during those 47 days; he was particularly interested in the debate between Choi Myung-kil and Kim Sang-heon, and in King Injo, who had to decide between their positions.¹¹^•²

The first script reading took place on November 11, 2016, and filming ran from November 21, 2016 to April 25, 2017.¹ The film was produced by Silran Pictures and distributed by CJ Entertainment.³ Kim Ji-yong served as cinematographer and Ryuichi Sakamoto composed the score.⁶

Style and reception

A war film without battles. Reviewers noted that the film contains almost none of the large-scale battle scenes usual for war films; after the midpoint it shows only brief episodes of one-sided Qing attacks. SBS's commentary described it as a film about a war of words, a "chess match of tongues," centered on the debates between the two ministers rather than on combat.¹¹ The Korea Film Archive's program note highlights the long takes that establish the film's atmosphere and the close-ups that carry the verbal duel between Choi and Kim.¹⁰

Critics also observed what the film does not dramatize. SBS's review noted that because the focus stays on the court's conflict, the story of common people is not prominent; Go Soo's blacksmith Seo Nal-soe, who represents the populace, does not leave a strong impression.⁴ The same review praised the depiction of the Samjeondo submission, in which Injo bows three times and knocks his head nine times before the Qing emperor, filmed from a low angle behind the bowed king with the emperor seated high on a platform.⁴

Box office and audience response. The film drew 3,829,891 admissions in South Korea.³ SBS's analysis attributed its falloff after an explosive first week to the subject: audiences had little appetite for watching a losing war, and the debate ends in a humiliating defeat with no catharsis of victory.¹¹ On the review aggregation side, Cine 21's five critics averaged 7.40 out of 10 and audiences 7.64.³

Kim Hoon, the novelist, said after seeing the film that the producer has the discretion to create the movie, but that The Fortress conveys his intentions well.¹²

Awards

At the 37th Youngpyeong Awards, presented by the Korean Association of Film Critics on October 26, 2017, The Fortress was named Best Film and also won for directing, cinematography, and music, four categories in total.¹³ Cinematographer Kim Ji-yong won the Golden Frog at the 26th EnergaCamerimage film festival.¹⁰

Distribution and later availability

In November 2021, Netflix added The Fortress, together with Hwang Dong-hyuk's Silenced and Miss Granny, to its service in the United States and South Korea, following the success of Squid Game.¹⁴ As of a September 2026 check by JustWatch, the film was streaming on Netflix, Watcha, and TVING in South Korea, with rental on wavve.⁹
