Perhaps you can identify which one is the correct Big-5 name for Joseph Koo? It appears the one that I renamed under Goo Ga Fai (2) is the correct one. Another indication that the two should be merged into one.
I recently updated Happy Ghost 3 and noticed that Goo Ga Fai was in the end cast list. I didn't see him in the movie. It's possible that I may have blinked my eyes, and missed him. If somebody else spots him in the movie, we can delete the new one I created and add the original in the cast list.
Okay, I've moved the Happy Ghost 3 credit and deleted the 2nd Goo Ga Fai entry. I've also changed the Big 5 name from 顧家輝 to 顧嘉輝 which seems to be the correct and more common one for Joseph Koo.
