I wrote a similar response last night, but being a bone head, I didn't save the draft, then when I clicked submit it took me to the sign in page and my text was lost
Like Bob, I'm not opposed as such, I don't have strong feelings on it either way. But I think it's better having the full (English+Chinese) names. I'll put my reasoning below for you to consider, if they're not things you've considered already.
Firstly, it helps distinguish between people with the same/similar names, a good example is the name Tony Leung and the various people who share that name, obviously this isn't directly equivalent to the people you've listed as there's only one Ringo Lam etc. but only for now, it's possible that there may be another Ringo Lam and the Tony Leung situation would become relevant. In line with this idea, is the consistency of the names, if we do have Tony Leung's with the full names, shouldn't everybody have full names (where available), if just for the sake of consistency?
Secondly on a lesser point, I think it could be useful for those who are only aware of a person's Chinese name or English name exclusively, it makes it more likely for them to become accustomed to both names if they're right there in their face. This can be useful to researching martial arts films, the more people who know both the English and Chinese of actors etc. the less chance of confusion when different sources switch back and forth between the two. I hope this makes sense, it might be a bit ramble-y.
As I said, not strong feeling on it either way, but those were my thoughts.
Cheers
btw: can't say I'd heard Donald Chow Yun-fat before, sounds kinda lame like Collin Chou
