Ricky Lau directs this fantastically successful horror yarn that successfully fused high-flying slapstick with creepy genre atmospherics. The film opens with Taoist priest Kau (Lam Ching-ying) along with his two hapless assistants, Chou (Chin Siu-ho) and Man Choi (Ricky Hui Koon-ying), set out to fix the Yam family's recent streak of bad fortune. The priest soon concludes that a vengeful feng shui master had tricked the family into burying its elder in a manner that was bound to reap bad luck. Yet before the problem could be corrected, grandpa comes bursting out of the ground and kills his son. When the son returns from the great beyond to reek havoc on the living, Kau eventually manages to put him to rest for good, though gramps continues to terrorize. Meanwhile, Chou has been seduced and bitten by a beautiful spirit and will turn into a vampire unless Kau comes to the rescue. This film not only launched four sequels, but the whole horror-comedy subgenre that exemplified Hong Kong cinema during the late '80s and early '90s.
