Here's one HK film not yet listed on this thread:-
A friend mentioned that God of Gamblers Returns (賭神2) starring Chow Yun-Fatt, not the one starring Andy Lau & Chow Sing Chi (賭俠), has an altered ending to please the authority as well.  In the original HK ending, Chow YF's character kill the bad guy with a samurai sword.  In some countries ending, Chow YF's character is caught by the police (maybe after killing the bad guy) and got some character giving advice something like, "Berjudi adalah salah di sisi undang-undang." ... my fren said according to the Malay subtitle ... 

Anyone care to verify?
