The images were captured from 5-7 minutes that I ripped with the intention to capture the opening and ending credits so it's not impossible that Tai Bo and Goo Goon-Chung might be in the movie. I will try and watch the whole movie today or some other time this week and see where it leads.
Is it possible that we have two different movies or a cast list with mistakes?
And with a look at the cast images I would guess the movie is older as 1996 (look at the hairstyles and the make up).
Not sure, but Hsing Bao Art Screen Co. is probably responsible for have been editing this particular version in 1996 (listed on the Tai Seng-case), and I agree about the age of this movie is older than that.
That's him, thanks! (added)
Wong Tao: I would not be sure enough to add him
Removed his name for now, hopefully we can be 100% sure one day, but it certainly looks a lot like him doesn't it?
