I don't know if you guys add voice actors to movies or not.But i see some actors were lsited as "voice only".
Anyway i found something.
Just watched Taxi Driver (David Chiang).Tung Lam's voice was dubbed by Stanley Fung (in cantonese version).As we know Stanley Fung is an actor so i think we should add him as the voice only.One more thing Stanley Fung used his own voice in most movies.I think he dubbed in 1 more SB film,but i forgot which one.Hope you'll add him to cast.

If I remember correctly Stanley Fung is the Cantonese voice of Chen Kuan-Tai in TEA HOUSE or/and BIG BROTHER CHENG.

He is also the voice of Chung Fat in his movie PHANTOM KILLER.

Right,i saw Phantom Killer as well and now i remember.Thanks.
