Liu Chia-liang is arguably the best martial arts film director of traditional style kung-fu action and was a pioneer in focusing on authentic martial arts techniques and training procedures in his films. This is why stars in his movies looked more like kung-fu experts rather than actors simply going through the motions. So although David Chiang had starred in over 40 films as a martial arts hero, in Shaolin Mantis, where he plays a man who learns martial arts from a praying mantis, then seeks revenge for his wife's death, the movie contains some of Chiang's best fight scenes ever. By casting his brothers Liu Chia-yung and Gordon Liu Chia-hui into the mix, Liu further ensures that the pugilistic mayhem will be even more outstanding.
