Likely match:

http://hkmdb.com/db/movies/image_detail ... ay_set=eng
13 Worms (1970)

http://hkmdb.com/db/movies/image_detail ... ay_set=eng
Champion Of Champions (1972)

http://hkmdb.com/db/movies/image_detail ... ay_set=eng
Murder Of Murders (1978)

Seem to match #9 on http://www.angelfire.com/az3/chia/castc/ffi.htm
Fearless Fighters (1971)

The actor in 13 WORMS and 9 in FEARLESS FIGHTERS could be the same, but the actor in CHAMPION is in my opinion not the same and I have my doubts with the actor in MURDERS.
