The story is a re-tread of well worn fare among Shaw Brothers product popular from 1967 (ish) to about 1971 when Bruce Lee's popularity changed the style & fashion of these films away from weapons towards more fist & feet Martial arts.
The story is easy to follow, has a good pace & is intriguing without breaking any new ground.
What is exceptional about this is the action , with fast, intricate
& inventive interactions . This is achieved by being slightly under cranked when filming, which became the norm from the early 1980s's... yet this was filmed in 1971 !!! Strangely, it was held back from release for about 3 years.
This is one of Yuan Has best fight showcases (though not his best Acting showcase!)
Other directors helped pioneer this exciting technique , such as Joseph kuos films of the time, and by the early 80's Directors such as Tony lau Jun Guk were pushing it to (& beyond ) its limits. Jackie Chan & Sammo Hung are the best known directors who regularly use this technique. Sammo appears a few times in this, and may be the villain who gets a sword in the head during the Inn Fight ? Jackie Chan also makes a brief appearance as an extra, though you have to look hard to spot him.
This film was very likely where many of the future Golden Harvest stars first met or discussed their forthcoming exodus, as well as certainly during the later ShawBros films of Lo Wei.
The direction is excellent, full of zooms, fades, and top-notch editing. The Direction & Choreography team is one of the best - all the other films by these talent folk are worth checking out-
For me one- of the greatest unsung craftsmen of this genre is Simon Chui Yee-Ngau, a man responsible for the action in many brilliant films, often in collaboration with Chui Chung-Hok.
Tsui Siu-Ming (of Gang Master, Buddhists fist, Holy Robe, Bury Me High etc) is Simon CYN skillful younger brother.
Tien Feng has a brief appearance & is excellent as always as a skilled villain, this time dressed in the red & white 'santa' clothing of the Tartars.
1971 was a golden year for Shaw Brothers & Martial Arts/Action films from Asia. There are at least a dozen film for Shaws that year that all serious fans of the genre should check out , if they haven't already.
This film is certainly one of them, and if it is considered 'average' for the time that average is at a very high standard !
....& Granny Ba is great.....
