+ unlisted actors :
Ha Ngo Yin
Kwok Man Fong
Leung Hin Yung
Pang Fung Kwan

Never ceases to amaze me - the number of movies featuring Leung Kai Chi where he isn't credited. And his support role is substantial here. He must use a battalion of aliases - perhaps Leung Hin Yung is one of them.

"Production Manager
Chow Yiu-Shan"

Nope. Tommi Lee Wing Hon (unlisted) is so credited.

And what do these acting credits mean ?

ID Chan Siu-Wah

Corrected Dang Taai-Woh (VENDETTA was one of the movies who helped me to make his ID a few years ago)
