Consider this poster :

for I Love You Baby (2003)
http://hkmdb.com/db/movies/view.mhtml?i ... ay_set=eng

Acting credits include this name : ???
with only one credit :
Assistant Director (1 film)
Witty Hand, Witty Sword (1978)
http://hkmdb.com/db/people/view.mhtml?i ... ay_set=eng

Similar characterization (same sound) is ???
which is this guy
http://hkmdb.com/db/people/view.mhtml?i ... ay_set=eng

who looks very like the guy with the high hair in the poster above, and he appears to be the same age, not 20 years older.

Also, I think the year 2003 looks rather late for the people involved. It looks more like late 80s or early 90s. If the year has supporting evidence, could it have been held over for release for some years ? This sort of thing did happen with some of these adult cheapies.

I believe it could be a retitle for this movie :
http://www.dianying.com/ft/title/20300 - which dianying says made in 1987, which is consistent with the career spans of the people involved.

The plot thickens further.
The director Yang An-He, above, has a dozen films to his credit on dianying :

... covering 1987-89.

Also, Dan Yang's film career appears to have finished in 1991, with only ILYB in 2003.
Similar story for Chan Kai Chun.

In case there is any doubt from the post above, I intend to do the following in a few days, unless prevented :

1. Merge ??? into ???

2. Change
http://hkmdb.com/db/movies/view.mhtml?i ... ay_set=eng
from 2003 to 1987, adding http://www.dianying.com/ft/title/20300 as an alias.
