Killer Clans (流星蝴蝶剑)

Killer Clans (流星蝴蝶剑) is a 1976 Hong Kong wuxia (Chinese martial-arts fiction genre of chivalric heroes) film produced by Shaw Brothers, directed by Chor Yuen (楚原), scripted by Ni Kuang (倪匡), and adapted from Gu Long's (古龙) 1973 novel Meteor, Butterfly, Sword. The assassin Meng Xinghun (孟星魂) is hired to kill Sun Yu (孙玉伯), head of the powerful Longmen Society, but falls in love with Sun's daughter and is drawn into a power struggle in which Sun's trusted lieutenant Lü Xiangchuan (律香川) is secretly a traitor.¹ The film was the first of roughly twenty Gu Long adaptations Chor Yuen made at Shaw Brothers, and its success opened a craze for filming Gu Long's novels.²

Plot and characters

The story is built on clan politics and betrayal. Meng Xinghun, a freelance assassin, is hired to kill Sun Yu, the head of the Longmen Society, the largest gang in the martial world; on the way he meets the mysterious woman Xiaodie (小蝶) and a misty romance develops.¹ Sun Yu's trusted aide Lü Xiangchuan is in fact a traitor, and once Sun sees through him a fierce fight to the death follows.¹ Time Out's review describes the film as essentially a triad gangster movie in period dress, centered on the struggle for underworld supremacy between the Longmen and Roc clans, with the dramatic focus on the trust, or rivalry, between Sun and his lieutenant.²

The cast maps onto these roles: Tsung Hua plays Meng Xinghun, Ku Feng plays Sun Yu, Yueh Hua plays Lü Xiangchuan, Ching Li plays Sun Die, Chen Ping plays Gao Jiping, Lo Lieh plays Han Tang, Wang Hsieh plays Wan Pengwang, and Ling Yun plays Ye Xiang.³ The Hong Kong Film Archive notes that the film mixes adventure, suspense, chivalry, romance, and eroticism, with a surprising ending.¹

Production background

By 1976 Chor Yuen was in a difficult stretch at Shaw Brothers. After the success of The House of 72 Tenants (1973), several television adaptations failed at the box office, and he spent nine months without a film to direct.¹ According to a Concordia University master's thesis on Shaw Brothers genre filmmaking, Chor had pitched new-style swordplay adaptations to Run Run Shaw and been rebuffed each time; the project moved forward only when the trusted screenwriter Ni Kuang proposed filming Gu Long's recent novel Meteor, Butterfly and the Sword, itself loosely inspired by Coppola's The Godfather (1972), on condition that Ni write the script.⁶

Ni Kuang's screenplay cut several key characters from the novel to streamline it, but Chor quietly revised the script and put them back, making the film closer to what he had wanted.⁶ The Hong Kong Film Archive's account agrees that Chor, with Ni Kuang's help, turned the Godfather-inspired novel into a screenplay and thereby set off the Gu Long film boom.¹ Gu Long himself later said the novel was a tribute to The Godfather.⁷

Style

Chor Yuen's approach set the film apart from the Shaw Brothers wuxia of the early 1970s. The Hong Kong Film Archive credits him with a "Chor Yuen style" of aesthetic romanticism, and lists Killer Clans and The Magic Blade (天涯．明月．刀, 1976) as the works that established a new wave of romantic, strange-toned wuxia at the studio; it ranks him alongside Li Han-hsiang, Hu Jinquan, and Chang Cheh as one of the "Four Great Directors" of Shaw Brothers.⁸ The action was choreographed by Tang Chia and Yuen Cheung-yan, the latter the brother of the choreographer Yuen Woo-ping.³^•⁹

The International Film Festival Rotterdam program notes that Chor gave full rein to his artistic sensibilities in the sets, staging vicious fight sequences against whimsical, poetic scenery, a contrast the festival described as bringing a sense of modernity to the ancient genre.¹⁰ A review in Slant Magazine of the film's Blu-ray release calls it an opulent, Godfather-esque wuxia with expressionistic color and precisely ordered production design, showing how elaborately staged and arty Shaw Brothers could afford to be by 1976.¹¹ The critic Sek Kei, writing in 1976, called it an above-par work of the martial arts genre that signaled Hong Kong cinema's move from visually dazzling flicks toward richly developed plots.¹²

Reception and legacy

The film performed well commercially. It earned HK$1,596,557.2 in Hong Kong and placed seventh among the year's top-grossing local films.³^•⁴ Released in Taiwan on 17 April 1976, it broke that year's Taiwan box office record and won Chor Yuen the nickname "Chu Qianwan" (楚千万, "Chor the Millionaire").⁵ It also received the Best Art Design Double Lion award at the 22nd Asian Film Festival.⁵

A template for a cycle. The film's success pushed Chor Yuen into a string of Gu Long adaptations at Shaw Brothers, including The Magic Blade (1976), The Sentimental Swordsman (多情剑客无情剑), and Death Duel (三少爷的剑); Time Out counts roughly twenty such films, and the Hong Kong Film Archive's oral history records that Chor alone adapted eighteen Gu Long works.²^•¹³ The Archive's retrospective program describes Killer Clans as the entry with which Chor established the mini-genre of the "martial-arts suspense thriller" as a mainstay of 1970s Shaw productions, a trend that also spread to television.¹⁴

The film has remained in circulation. It was shown in the Hong Kong Film Archive's 2023 Chor Yuen retrospective marking the first anniversary of the director's death (Chor Yuen died on 21 February 2022 in Hong Kong),¹^•¹⁴ and Shout! Factory included it in its Shaw Brothers Classics: Volume Three Blu-ray box set in 2023.¹¹ A 1993 remake, Butterfly Sword (新流星蝴蝶剑), starred Tony Leung, Michelle Yeoh, and Donnie Yen.¹⁵
