This is the worst of the Sammo Hung films of the old-school chop-socky 'fu film era that I've yet seen. Hung is burdened with an ugly wig - a wig conventional to Cantonese comedy, it indicates that the character never washes his hair. This would be mere annoyance, except that the wig is actually the whole point of the movie! Hung is even made to use it as a weapon in hand-to-hand combat! Hung did not write, direct, or even choreograph this mess. The film is clear indication that the chop-socky film producers had not the slightest idea of what to do with the new generation of 'fu stars showing up in the period 1978-1980. Obviously, knowing Hung was beginning to earn a reputation for comedy, the producer decided to hire him for what the producer obviously thought was a funny script. The humor is so low, you can scrape it off your shoe. Hung mugs like the village idiot. This is a far cry from the sophisticated comedy Hung himself writes and directs. And the kung-fu? well, if the dirt on the top of a guy's head counts as a weapon, what sort of fighting can one expect from this? The surviving English-dub video of this film is the worst pan-and-scan job I've seen in a long time, and the dubbing ridiculous.
Remember that Hung had already directed the far more polished Iron Fisted Monk by the time he made this film. Clearly he's just picking up a few bucks as quickly as possible. Wish I had known him back then, I'd have paid him not to make the movie! The two stars is for the performance of Carter Wong as the bad-guy of the pic.
