Watched the 1977 movie and captured the cast/crew credits there since they fit with this "version"
http://hkmdb.com/db/movies/credits.mhtm ... ay_set=eng
But the movie is clearly that shown on 1972 version poster and review I linked from Thai Film Database
http://hkmdb.com/db/movies/view.mhtml?i ... ay_set=eng

But the director and actors are different...

Added 2 actors.

I also watched a chinese version of SNAKE QUEEN with that credits appearing in the opening titles:

http://hkmdb.com/db/movies/credits.mhtm ... ay_set=eng

It is the same movie reviewed at the Thai movie database (exactly the same story and the images on the poster fit):

https://www.thaiworldview.com/tv/movie. ... b1=2&nb2=3

The cast (and most likely the crew) is purely Thai.

On the chinese version of the original poster are partly other names listed as on the credit images of the 1977 entry:

http://hkmdb.com/db/movies/image_detail ... ay_set=eng

But in my opinion it is nevertheless the same movie.

The chinese names (cast and director(s)) are in my opinion only placeholders for the original Thai cast and crew, only listed for the chinese versions.

In my opinion we should merge the two entries.

OK if nobody stops me in 15 days I will merge them.
