Jim-Yuen Yu, Jackie Chan's real life kung fu teacher, stars in his first (and last) big screen fight flick as 'The Old Master'. Unfortunately, he left making his debut a little too late, and is doubled in all of his action scenes. With Jim-Yuen obviously struggling to fight off senility and arthritis, it is left up to Chinese-American Bill Louie to impress viewers with his martial arts skills; and this he does, but only towards the end of the film.The wafer thin plot involves The Old Master being tricked into fighting, by his friend, who is secretly betting on the outcome in order to pay off debts. When the Master finds out, he shacks up with a disco-martial-artist (Louie) who convinces the old man to teach him the secrets of Kung Fu.If you can get past the weak first hour (the highlight of which is The Old Master dancing with a fat woman to a disco rendition of Popeye The Sailor Man!!), there are some nifty fights in the closing moments, including a good roof-top battle, some weapon work and Bill Louie doing Robotic-Fu.I recommend a few beers before viewing.
