One Armed Boxer(1971)
Directed by Jimmy Wang Yu
One Armed Boxer (独臂拳王) is a 1971 Hong Kong martial arts film starring Jimmy Wang Yu. It is about a skilled Chinese martial artist who loses an arm and must exact revenge on his rival school.
For the film, Wang Yu, who has both of his arms in real life, had his armed strapped to his back, and some shots his other arm can be briefly seen.
Tien Lung, the best fighter at the Ching Te martial arts school gets into a fight with the local Hook Gang at a restaurant where Tien Lung and his friends are dining. The Hook Gang are part of a local opium-dealing and prostitution ring run by a man named Chao and are rivals of the Ching Te school. The Ching Te school is the most prominent martial arts academy in town and controls the local clothes-dyeing and brick factories. In a quick battle, Tien and his friends easily defeat the Hook gang both in the restaurant and again later in the valley where they have a battle royale.
Chao plans his revenge by hiring a group of mercenary martial artists from Shanghai. This group consists of two karate experts and their teacher, a Judo master, a Taekwondo expert, two Thai boxing fighters, a Yoga expert, and two mystic Tibetan lamas (who are later revealed in the sequel to be students of an Imperial Assassin). With this group, Chao easily destroys the Ching Te school and all of their businesses, leaving everyone dead except for Tien Lung who loses his right arm. Tien Lung vows revenge and begins his training to destroy anyone and everyone who stands in his way.
The foreign mercenaries hired by Chao to fight against the Ching Te school.
One Armed Boxer was followed by Master of the Flying Guillotine, with Jimmy Wang Yu reprising his role as the one-armed kung fu master Tien Lung. With his arm strapped behind his back, Wang Yu had earlier portrayed the One-Armed Swordsman in two films for the Shaw Brothers Studio.
