Another student of master Jim Yuen, he can probably hang with the best of the (or at least some of them). A martial-artist of tremendous talent, his only problem is that he did get enough chances to display it. With classmates like Jackie Chan and Samo Hung, you know he knows his craft well. It's a shame that he didn't receive film roles, as early as most of his other classmates, as there's no telling, what we may have seen from him. He started out at Golden Harvest -- in mostly bit parts. In the late 70's he moved to Shaw Brothers and began getting noticed and snagging better roles.
In The 5 Superfighters, he showed excellent movement and timing when displaying his skills, though I thought he was outclassed by Huang Kuang. He had to impress someone at Shaw Bros', because they gave him the starring role in the obscure classic, Boxer From the Temple. It would have been nice to see him in other starring roles, because his career only seemed to be taking off. He showed that he had the type of skills, that made his former classmates stars, and the idols of millions of fans.
To be at Shaw Brothers, where there was a great deal of talent floating around, he definitely would have had to work much harder to get better movie roles. His role in The Delivery (a cameo as a thug) was so quick that I even missed him the first time. As with most of these truly gifted actors, if they don't get the right roles, we'd never know their true talents. This Billy Chong look-a-like, though he's appeared in more (known) feature films, could only wish for the former's popularity, within the genre.
