Saw the movie. Song lei is not in the cast list but Sunny is.

HKFA, does not have Song lei on its list but Sunny is.

Also, the role of CID is a male cop questioning Gordon and Song lei is a female.

Therefore I believe Song Lei's alias "Sunny" is wrong and they are 2 different person. HKMDB shd list Sunny and not Song Lei as the CID.

The movie list Chin Wing-Lai / (錢永勵) as the sound recordist and not chin wing wai. HKFA support it.

Can anyone confirm and update?

The alias of Sunny of Song Lei is correct. 桑妮 means Sunny.
Maybe there are 2 Sunnies. If nobody stops me in 15 days I will split them.

Changed sound recorder.
