Boxer From Shantung (1972)
I previously only knew this film from the 1997 Corey Yuen remake, called "HERO", which it turns out is really very different. Although the direction in BOXER FROM SHANTUNG is much better, I thought that the story, production values and some of the action in Hero were better.
However, BFS has Chen Kuan-Tai ("Introducing Chen Kuan-Tai" no less - I thought he'd been around for longer than that), and he is infinitely cooler than Takeshi Kaneshiro. Generally a good film, with a great, long and very bloody final fight.
