A rather extreme example of screw loose Chinese film-making from the 1980's. An era where HK and Taiwanese films were fast-paced, illogical exercises in frenetic film making, this one really takes the cake and sits on it.
The plot is threadbare and indecipherable at the same time. The scenes unfurl to strike the film makers fancy not to move the story along. It's really clear that the people who made this didn't care if the legendary spider boats obviously don't work or that the film is set in some sort of time warp between the 1920's or the 1980's. The American monks seem to be parodies of the Hare Krishnas that used to plague the airports and the Black Monk of Harlem is inspired by "The Last Dragon" but everything else seems to set in old China. The digging ninjas are first shown struggling with their small shovels, then suddenly they are drilling thru the ground at 50 miles per hour. The producers of the film didn't take this seriously and neither should the viewer.
The unusual nude fight scene is the first example I've seen of Taiwanese film nude kung fu that I had heard about from a friend who lived in Taiwan in the late 1980's. He had collected a number of these films which were subsequently confiscated by HK customs when he came back. Apparently these scenes were the rage for a small time in Taiwan. My friend had actually acted in one film (as a stock white bad guy) where he had to fight a heroine who practiced "Iron Chest". You can guess how that was used. The scene in this film is more of a shock then good. Most of the nude part of the fight involves the actress being flung around while she tries to cover herself with a sheet. She finally starts to fight back but the choreography seems to have been designed to cause the most amount of jiggle instead of an effective fight scene. And the jiggle isn't that good either. Eventually the actress must have said "enough" and she is suddenly clothed in a two piece bikini she somehow creates from the single sheet. The next scene she is in, she is killed off. They probably couldn't afford her anymore.
Good for a laugh with a group of friends, that's it. Except for the nude fight even my wife enjoyed the film and she doesn't like kung fu films.
