I cannot see well enough the category symbols, so I did not find the art director and other people.
Added 1 actor, prod., prod. manager, phot., editor, story (Ku Lung ) and music composer. He is our friend Chan Wing Yuk.
Now I am more sure he is Frankie Chan. Frankie directed "I.Q. Dudettes" and that films was written by "Chan Wing Yuk"! It would be his first credit as writer... so I think maybe it's a "personal wink" or something like that...
Is it possible Chan signed his GH films as "Chan Fan Kei" and his SB films as "Chan Wing Yuk"? (similar to Chan Wan case????? )

If anybody objects in 30 days, I will merge (or link, if our debate ends with that rule) Frankie Chan and Chan Wing Yuk...
