For posterity, this is post number 1 -- on the left is the entry we have in the database, and on the right is the name the actor/actress should be listed under as that is the name they have frequently been billed as onscreen in the movies.* In my first list I am tackling the actors from the Latest Movies (2005) entries:
1. Hon Kwan Ting (alias) - should be - Belinda Hamnett (actual name)^
2. Chung Lai Kei (Cantonese name) - Margaret Chung (English name)
3. Yiu King, or Yiu Yiu (Cantonese name) - Shannon Yao (English name)
4. Chiu Suet Fei (Cantonese name) - Chloe Chiu (English name)
5. Lee Siu Pooi (Cantonese name) - Zuki Lee (English name)

20. Wong Kwok (Cantonese name) - Huang Jue (actual name)+

^ in the instance of actors/actresses born outside of HK, and of mixed heritage, perhaps it is better for us to credit them by their screen credited names as opposed to Cantonese aliases?
+ where Mainland Chinese actors have appeared in a HK production, would it not be better to credit them by their usually billed screen name (eg: Mandarin) than a Cantonese alias that no-one (outside of us) knows?
These are just some suggestions that I'm throwing out and people are welcome to agree, disagree or debate their worth. When I write my own reviews, except in rare instances, I credit all actors & actresses under their most commonly know (current contemporary) name -- because I know there's a whole world of people out there who would scratch their heads in unison when reading a review of, for example, INITIAL D who would ask where Jay Chou was in the cast list...if I listed him as Chow Kit Lun. I figure, if I can pick up a music CD with the name Jay Chou on it, then I most certainly can attribute the lad by that name when I review him in a film...

* if anyone requires visual evidence of these, please request and I will post the screen credit as billed for verification.
