Chan Hung (1) IDd.

I must have blinked when Wellington Fung appeared. Was it near the start or near the end ?

There is one more (unlisted) actor to add - Chan Go Chai.

I'm not quite sure about the ID for Shing Gwan On. The actor is one of the three guys who appear in the brothel room after Hansom Wong crashes through the wall. I have no idea what the role "lorry driver" refers to for these two guys.

And the family resemblance is really strong for Mama Hung here.

ID of Tam Wai-Mei

Corrected Chiu Jun-Chiu

Removed wrong Shing Gwan-On ID (is Garry Chan)
Removed wrong Shing Fui-On ID (is David Ho - added)

The real On brothers appear (if I remember it correct) in a few scenes in the middle of the movie working in the front of the house. I believe they have no good close-ups.
