I consider Liu Chia Liang (Lau Kar-Leung) the most important person in the history of martial arts movies. I call him the Grandmaster. No man can better tell any story about Wong Fei-Hung. Liu Chia-Liang learned martial arts from his father, a student of Lam Sai-Wing, who was a student of Wong Fei-Hung himself. Liu Chia-Liang honed his skills as stunt man and then action choreographer beginning in 1953 with the Wong Fei-Hung series of movies starring Kwan Tak-Hing.
His personal golden age of directing martial arts movies began in 1975 with "The Spiritual Boxer." His other movies "Challenge of the Masters", "Executioners from Shaolin", "Heroes of the East", "The 36th Chamber of Shaolin", "Dirty Ho", "My Young Auntie", and "Legendary Weapons of China" are among the top ten martial arts movies of all time.
I am often asked "What was the best martial arts movie ever?" and my subjective answer has been "Legendary Weapons of China". I am also often asked "What was the best fight scene ever?" Like the other question this is really impossible to answer. It is totally subjective and how does one even define the qualities that make the best fight scene ever? Yet, I can tell you this with no doubt, on May 7, 1976 (the release date of "Challenge of the Masters") the best fight scene ever filmed as of that day was the fight scene in that movie with Liu Chia-Liang against his brother Lau Kar-Wing. The runner –up would be his fight against Gordon Liu in the same movie.
