This is a classic Shaw Bros kung fu film from master martial arts movie maker Lau Kar Leung.
It is about students of the Shaolin temple who seek revenge after Pai Mei destroys Shaolin and kills it's masters.
It's main protagonist travels with his brothers on the red boats under the guise of Opera performers all the while training for the confrontation with his nemesis, Master White Brows.
Chen Kwan Tai is excellent in the lead and is ably supported by Lo Lieh, Li Li Lee and an early appearance by Lau Kar Fai.
The movie features traditional Hung Gar Kuen techniques and they are excellently performed By the stars.
I have had it only a week and have watched it 5 times so far. Considering the year it was made the action choreography is very complex but extremely well executed and watch out for Lau Kar Leung as a villain wielding a 3 section staff. good stuff!!
