Indeed there was a series of “Wisley” films, of which this is one. Wisley was an occult expert played by different actors in each film. In this case his name has been transposed to Wesley.
|Yuan enters the building|
She chases after him, looking to do a feature on him, harassing him at a party. He loses her and gets home and is about to have some nooky with a lady friend when he is accosted by a man, Black Dragon (Dick Wei). They fight, wreck the place and then talk. Black Dragon wants him to return to Thailand, Yuan has a blood curse on him and he will die soon. Betsy (Sau-Lai Tsui) is also cursed, he must save her. He is also told no nooky as he will die sooner – some nooky later and a curse bursts from his body.

|Ancient Ancestor attack Yuan|
Ancient Ancestor is the one that gets me thinking of this as a vampire film – or at least with enough elements to warrant a place on filmographies. I will say, for fans of Yun-Fat Chow, his role is little more than a supporting, perhaps even a cameo, role. The imdb page is here.
