Added 21 portraits for 15 actors. There are 3 out of 5 leading actors (1 female) have no credits or ID yet.
I really hope that impressive actor who plays Akayama will be Andrew Yu Ming-Hong (who's only portrait is useless - sorry)
He appears in the both prequel too (http://hkmdb.com/db/movies/image_detail ... ay_set=eng)
and http://hkmdb.com/db/movies/image_detail ... ay_set=eng !!!!

The General appears in all 3 parts too and he is not ID yet, too - what a pity - a great actor, too!

The actor playing Kasai Yamada seems not to be Wan Man-Ying who's nose and lips look different (Could it be a wrong ID then?)
Still it is

by the General, are you referring to this guy?

Men Behind the Sun (1988)


Laboratory of the Devil (1992)


Narrow Escape (1994)

I'll try to pull credits and see if we get a hit on common names...
