This movie was actually made in 1989 in Taiwan and is called 賭國恩仇 (Gambler's War)
I am going to change the titles and year soon and also remove the credits for Mascot International and Polly Kiu/Chiao soon as they only apply to the retitled HK version.

Done. I also added the release date and some more credits.
