Unknown SB-Actor(28) http://hkmdb.com/db/people/images.mhtml ... ay_set=eng
plays quite a great role in "Hex after Hex" but there was none of the 22 names in the credits not ID yet - Is he realy not listed?.
But I found that Tang Yuk-Win for example in "Gang Master" (1982) Passing Flickers (1982) Godfather from Canton (1982)
looks quite similar to him!! Maybe he plays a double role with/without beard?

In my opinion it is not the same actor.

But why is no name listed for him?

Many actors are always uncredited or rarely credited in movies, even with good roles.

Tang Yuk-Wing als example is also not credited in any of the Shaw Brothers movies listed in his hkmdb filmography. His ID was made because of movies after his time at Shaw Brothers and his TV appearences.
