Cheh Chang filler, though he got a little help from Hsueh Li Pao this time around. The plot is situated in a slightly more modern setting (at least, compared to most other Shaw Bros martial arts films), which usually doesn't pan out too well. But the film stays clear from too obvious contemporary influences, so it doesn't come off all that outdated.
Man of Iron is a sequel to The Boxer From Shantung, with Shaw Bros legend Kuan Tai Chen reprising the role of Wan. Wan has amassed a large group of followers, but he isn't the only bad boy in Shanghai. It doesn't take too long before he butts heads with some of the more established gangs. And they're not too happy with this new kid on the block.
The plot isn't too interesting, the film also takes a little too long to get going. The martial arts is decent, but not the best Chang has put on screen. But he compensates with plenty of martial arts scenes in the second half of the film. It gets a lot better from there on out, though I still wouldn't recommend this film unless you're dedicated to completing Chang's entire oeuvre.
