no crews for this movie

Added
prod. companies, pres., prod. manager, exec. prod., planning, assist. dir., action dir., phot., mus., ed., art dir., costumes, gaffer
and 14 actors more.

Also thanks to your screenshot I found composers Peter Kam and CAM (Sing Gung Chong) are the same person.
So, if nobody stops me in 15 days, I will merge them.
