YEs this is the orignal movie which gave the premise to THE DUEL, though almost completely different movies, the similarities are easy to pick up

The problem i had with this movie is it's many plot twists and the name of the character,i was confused at times and wasn't quite sure who each character was.

Apart from this the movie was quite enetertaining, the action was a little better than average, and LAu Wing breezes easily through his role as the charismatic detective
Lu Xiaofeng

One of the better kung fu mystery movies made by SB
