Jackie's Role: Shing Lung, another young and lazy troublemaker who flaunts his martial arts skills but is soon on the path of revenge for the death of his grandfather. The Bad Guy: Yam Sai-kwoon, a Chinese martial artist/actor who was famed for having a crazy gleam in his eye and for being the token villainous martial arts master in nearly every 1970's and 1980's Hong Kong martial arts film. True to form, in this movie he plays a white-haired supervillain who is hunting down rival martial artists and whose martial art consists of poking and digging his fingers into people's skin. The Fight: Seeing how Jackie had incorporated snakes and cats in his previous film, this one features his weirdest martial arts experiment yet: emotional kung-fu. They say martial arts is all about keeping your emotions in check, but this movie gives that notion the finger and goes in the complete opposite direction. Subjecting himself to an emotional roller-coaster that would scare away any shrink, Jackie fights the boss by going from a blubbering crying mess to a laughing over-sugared kid before channeling his inner Trevor Phillips and just straight up killing him.If you imagine what Inside Out would've been like if Pixar had decided to add in some kung-fu into the mix, this fight would be the result.
