This is one of the better Angela Mao movie from the late '70s. Since she stopped starring in Golden Harvest's movie, her movies weren't as well made or distributed. She seemed to be more focused on her domestic life, which probably was the right move since pure kung fu action movies were starting to be passe around the time this movie was made.
Bruce Li is probably the most type cast actor of all time, but he's a good actor in his own right, holding on screen presence with his handsome good looks, and good martial arts skill.
Making this a one of a kind movie is that both stars are starring together in this movie.
What's amazing about Taiwan producers and directors is the way they fail to capitalize on the on screen talent of their stars. They'd rather stick to their pat formula for making movies, rather than exploiting the often great talent of their stars. This movie is no exception and it just drags on with boring scenes of the bad guys talking to each other, then more talking, and then more, ......and more. Another thing is that the movie has no atmosphere to it at all. The scene goes from a cheap office to a dirty alley, to a worn down warehouse, and the likes. There's not a single beautiful scene in this entire movie.
Anyways, if a movie of this caliber is above average, you can surmise how bad some of the other Taiwan made Angela Mao movies are. Don't expect too much from this movie, as you see little of Bruce Li, and even less of Angela Mao.
There are better movies made of Angela Mao from Golden Harvest in the early '70s. They are recommended far more over this one.
