By luck I stumbled over the castpage for "Poor Daughter-in-law" (1965) because just now a new stream-video of that movie was offered in Youtube.
Amoung those existing pictures I discovered the face of a supporting actor who seems quite familiar for an Hui-Brother's "The Private Eyes" (1976) fan.
He will be unforgotten for his funny shark's jaws against sausagge nunchakku brawl with Michael Hui. In 1976 he looks like 40 something and has been first credited as actor in 1975, I always wounder why he never appeared before, because of his apperance seems suitable for actor to me.
but now I am convinced I discovered him in a movie 10 years earlier: https://hkmdb.com/db/people/image_detai ... ay_set=eng He looks like a younger version of https://hkmdb.com/db/people/image_detai ... ay_set=eng - do You agree?
