A small titled portrait on the Fascinating Affairs poster gives a good idea of what this guy looks like.

Two other of his credited moves have more than 100 actor images each. Go for it !

I found the image of the poster on Facebook, here :

Interestingly, there is a link which says "with Alex Cheung"
https://www.facebook.com/alex.cheung.56
Seems likely that this is the director/actor's page.
Posts are only in Chinese.
Anyone game to contact him ? He could be a helpful source.

I'm now chatting with Alex Cheung on FB. He speaks passable English and seems interested in helping.

Thanks to whoever picked out and tagged the photos.
