Found and added this poster to The Rendezvous of Warriors

I think it's the same movie, clues:
1) Pai Ying and Paul Chun Pui (alias: Paul Chiang) star
2) poster lists Shaw Fung James as the director, could easily be an alias for Jimmy Shaw Feng.
3) Fighting choreography is credited to S.L. Lieung, could be an alias for Bruce Leung Siu-Lung.

Still trying to figure out whose aliases are Lee Sheung and Wong Nin Gan.

thoughts?

I think it is the poster of "Yellow Killer" of director Jimmy Shaw. "Yellow" also stars Pai Ying and has Lee Seung (Lee Sheung) in the cast. And "Yellow" is about a hitman. "Rendezvous" is about a gangster who is doing revenge.

You're definitely right - Yellow Killer also has Chan Siu-Pang as an action director, which is most likely the S.P. Chan referenced on the poster. I've made the switch and added aliases.

Thanks Michael!
