I liked this movie a lot... There's not much I can say that hasn't already been covered by Brian Camp. He covered everything, maybe more than you needed to know.
I thought it was great that he mentioned Lau Yuk-Pok (aka Liu Yu-Po, aka Liu Yu-Pu). He's right, she wasn't in a lot of films. For those who are searching for a little more info about her, i'll input the best I know of.
She was born in Taiwan on May 3rd 1963. She joined Shaw Brothers at their invitation in the 80's and played in "Winner Takes All", "Rolls, Rolls, I Love You", "Shaolin Prince", "Shaolin Intruders", "The Weird Man", "Portrait in Crystal", "Secret Service of the Imperial Court", "New Tales of the Flying Fox", "Butcher", "Thunderclap" and "Qin Yong (aka A Terra-Cotta Warrior)". She returned to Taiwan in 1985 after finishing "Qin Yong", and started a career in TV drama. Later she married Chang Chien-Chung, who worked in an advertising agency, and eventually emigrated to the United States.
In 1991, they gave up their careers to become missionaries. In 2001, she became a writer and published two books about herself as a mother and a patient (I would assume "cancer patient" but cant find a definite answer). She died on May 11th 2009. There's some commentary on the Celestial DVD edition of Shaolin Intruders about her.
