Martial Law: Lo Wei's Wuxia World [2 X Blu-ray]
 

The Black Butterfly (1968)               Death Valley (1968)

Vengeance of a Snow Girl (1971)

 

 

Presented here are three standout films drawn from Lo Wei's wuxia world: The Black Butterfly, Death Valley and Vengeance of a Snow Girl.


A prolific writer and director, Lo Wei found fame in the 1970s following the enormous international success of The Big Boss and Fist of Fury, his collaborations with the inimitable Bruce Lee. In the years before he kickstarted a kung fu revolution, though, he had been working on an accomplished series of wuxia pian for Shaw Brothers. Presented here are three standout films drawn from Lo Wei's wuxia world: 'The Black Butterfly', 'Death Valley' and 'Vengeance of a Snow Girl'.

In 'The Black Butterfly', a good-hearted thief acts as the Robin Hood of the martial world, robbing from the rich to give to the poor - and they begin by stealing a fortune in gold from a group of five ruthless bandits holed up at Five Devils Rock. Then, in 'Death Valley', the Lord of Chao Manor (Lo Wei) is murdered by his niece (Angela Yu Chien), leading to a bitter fight to claim his land and a clash between a hired swordsman (Chen Hung-lieh) and the Lord's heir apparent (Yueh Hua). Finally, in 'Vengeance of a Snow Girl', a young woman (Li Ching) takes revenge for her murdered parents, who were killed in a dispute over the legendary Tsui Feng sword - leading to a final showdown on frozen ground.

Lo Wei's 'The Black Butterfly', 'Death Valley' and 'Vengeance of a Snow Girl' are three of the finest wuxia films produced in the years before Bruce Lee's meteoric rise to fame would cause a tectonic shift in the Hong Kong film industry, as the era of kung fu loomed on the horizon.

***

Lo Wei, a prolific Hong Kong director best known for his later collaborations with Bruce Lee, helmed several wuxia swordplay adventures for Shaw Brothers Studios in the late 1960s and early 1970s, including the trio of The Black Butterfly (1968), Death Valley (1968), and Vengeance of a Snow Girl (1971), which showcase his flair for action-packed narratives blending heroism, revenge, and moral dilemmas.

The Black Butterfly stars Jenny Hu as a chivalrous female bandit who robs the rich to aid the poor, only to face retribution from a vengeful gang in a Robin Hood-style tale infused with witty swordplay and themes of generosity.

Released the same year, Death Valley features Yueh Hua and Angela Yu Chien in a gritty story of martial intrigue and betrayal set in a treacherous valley, emphasizing sharp action sequences and a biting edge of conflict among outlaws and warriors.

Culminating the set, Vengeance of a Snow Girl (1971) follows Li Ching as a crippled orphan wielding icy powers in her quest to avenge her parents' murder by four villains, delivering a frosty, focused payoff with supernatural elements and intense duels that highlight Lo Wei's evolving style toward more fantastical wuxia elements.

ADDITION: Eureka Blu-ray (August 2025): Eureka have transferred Martial Law: Lo Wei's Wuxia World to Blu-ray. with three films; The Black Butterfly (1968,) Death Valley (1968) and Vengeance of a Snow Girl (1971.) Shot in vibrant Shawscope widescreen, the films feature dynamic swordplay sequences with acrobatic choreography, emphasizing fluid movements and practical effects in outdoor settings that evoke ancient China's landscapes. Lo Wei's direction infuses the films with energetic action typical of 1960s Shaw Brothers wuxia. These 1080P transfers are sourced from 2K restorations of the original Shaw Brothers negatives. The visuals offer rich colors, pleasing details, and minimal print damage that preserve the era's dynamic cinematography and elaborate set designs without over-processing or digital artifacts. The action sequences, where acrobatic swordplay and colorful costumes standout against atmospheric backgrounds, marking a significant upgrade over previous releases although minor weakness remain inherent to the source material. Death Valley looks the crispest and Vengeance of a Snow Girl, with its fantastical visual style, is the weakest (veering to moiring and occasionally appearing waxy.) More grain would have been appreciated. But overall I was pleased with the HD presentations - notably the elaborate and lavish set designs and vibrant color schemes.

On their Blu-ray, Eureka use linear PCM mono tracks (24-bit) in the original Mandarin language. It offers clean and balanced sound that captures the original dubbing, sword-clashing effects, and musical scores without distortion or hiss, ensuring the films' energetic wuxia soundscapes - complete with dramatic orchestral swells and practical fight noises - are faithfully reproduced. The mono presentation is flat and era-appropriate, although there may be minor synchronization issues in dubbed dialogue as a limitation of the vintage recordings. The score for all three is credited to by Fu-Ling Wang (The Magnificent Trio, The One-Armed Swordsman, The Enchanting Ghost, The Flying Guillotine, The Dragon Missile, The Big Boss, Dragon: The Bruce Lee Story.) The auditory elements of The Black Butterfly blend seamlessly with the visuals, using rhythmic percussion and orchestral swells to heighten tension during swordplay, contributing to the film's old-fashioned charm. The sound design of Death Valley features effective integration of fight sounds like clashing weapons and impacts, supporting the film's seven action scenes without overpowering dialogue. Music includes an American surf-style tune during a sex scene, providing whimsical mood shifts, while the overall Fu-Ling Wang score is balanced and not overused, enhancing tension in betrayals and duels. Music in Vengeance of a Snow Girl incorporates sudden riffs from 007 and other Western soundtracks - it is whimsically lively and fitting for the unorthodox wuxia, with antagonists' henchmen occasionally acting as a choir in clairvoyant harmony to add eccentric auditory layers. The audio transfers appear authentic. Eureka offer optional English subtitles on their Region FREE Blu-ray.

The extras in this Eureka Blu-ray set are thoughtfully curated for wuxia enthusiasts, featuring new audio commentaries on all three films by experts Mike Leeder (editor of 100% Jackie Chan: The Essential Companion) and Arne Venema, who provide engaging insights into Lo Wei's direction, Shaw Brothers history, and action choreography; a fresh 20-minute interview "A Dish Best Served Cold" with scholar Wayne Wong discussing Lo Wei's career trajectory and influences; plus packaging highlights include a limited edition O-card slipcase with new artwork by Grégory Sacré (Gokaiju) and a collector's booklet with new essays on the films by Camille Zaurin. These supplements add value for their depth and relevance, offering contextual analysis that elevates appreciation of Lo Wei's pre-Bruce Lee work.

The Eureka Blu-ray set of Martial Law: Lo Wei's Wuxia World highlights the director's early contributions to martial arts cinema. The Black Butterfly stars Chiao Chiao (One-Armed Swordsman, Vengeance of a Snow Girl) and explores themes of social justice and chivalry in a corrupt society, portraying the protagonist as a Robin Hood figure who challenges class disparities by robbing the rich to aid the poor, reflecting broader wuxia ideals of righteousness amid feudal oppression. Retribution and forgiveness emerge as key motifs, as the narrative critiques vengeance cycles through the antagonists' pursuits, ultimately advocating for generosity and heroism over greed, though the execution sometimes lacks depth in dramatic tension. Death Valley with Angela Yu Chien (Hong Kong 1941, The Oily Maniac, My Name Ain't Suzie,) probes ambition and betrayal, portraying the titular location as a metaphor for moral decay where greed corrupts relationships, echoing noir themes of fatalism and deception in a wuxia context. Redemption emerges subtly through Chiu's internal struggle, underscoring the futility of violence in a treacherous world. Vengeance of a Snow Girl a fantastical wuxia featuring Ching Lee (The Ghost Lovers, The Human Goddess, The 14 Amazons) as a crippled avenger with icy powers, alongside Yueh Hua (Come Drink with Me) and Chiao Chiao, blending revenge drama with supernatural elements in Lo Wei's evolving style toward more mythic narratives. Praised as a superior Shaw wuxia with mythic depth, critics note strong performances and resilient themes. Wuxia genre enthusiasts will get a lot of entertainment out of this Eureka Blu-ray package. To that fortunate niche this is warmly recommended.
