| A "one hit wonder" if by "hit" you mean "just average"
It opens with a lesson in evolution. Next, the scientists discuss the plot. A fossil has been found that links human evolution. The evil Japanese are coming to steal it. Martial artists will be needed.
There are many martial artist/actors who seemed to come from nowhere to star in a few of these movies and then returned to nowhere. Yeung C. Lee is probably the strongest example of this phenomenon because he has only this movie credit as lead. His fighting is certainly good though he does copy a lot of Bruce Lee's actions and mannerisms but not blatantly.
If the viewer can get past the silly story line, one dimensional characters, and unrealistic actions and outcomes, then the fights finally start. Most of the fighting is hand to hand brawls against numerous attackers simultaneously. There is plenty of action in the second half of the movie. Nothing is special and nothing is bad either.
My copy is a digital file that plays on a HDTV as wide screen but small. The dialog is Chinese and the subtitles are Chinese over English.
I rate this movie as standard, average, middle of the road, as found in hundreds of other movies of this time and genre. My recommendation to the fans is take it or leave it.
