More a tongue-in-cheek action/comedy about hopping corpses than a true horror flick.

Lam Ching Ying is Uncle Nine, by far his best-known role - the Taoist "One Eyebrow" (there's no gap between them) priest. Lumbered with his two bumbling and daft assistants (boyishly handsome Chin Siu-Ho, and Ricky Hui), Nine goes about his business of settling and re-settling recently deal and restless souls, else they become hopping vampires who'll endanger the community.

And what a job! Nine is surrounded by incompetents - not only his two disciples, but also the police chief (loudmouthed, thick-headed and lecherous) who chucks him in jail at the time when he's most needed (i.e. the first vampire has killed a man, who also becomes one). The scene where Nine and Chin try to subdue the 2nd vamp before he kills them and the police chief is a scream.

Much of this film could have been sub-headed "Carry On Vampires", as it uses a similar knockabout/low comedy style. Later, Ricky is entranced by a lady ghost (a young and sexy Pauline Wong), and is tricked by her into fighting off Nine. In this scene,

Lam Ching Ying does one of my all-time favourite super-quick kung-fu moves : a flipping leg-clamp to the neck which brings his target flat to the floor. Unreal. The standard of the stunt work is simply excellent, particularly from Lam & Chin, and of course from Mr tall-dark-and-intimidating himself, the great Yuen Wah, as the main vampire. Oddly, action-star Moon Lee does nothing but decorate the set and look frightened as the standoffish and pretty Ting.

In summary :
Not really the classic that it's cracked up to be, but still pretty damn good, and still a must-see for any HK film fan.
