Seeding of a Ghost (Hong Kong, A Shaw Brothers Production, 1983) --

This category III Hong Kong movie is full of sex & nudity. Irene is cheating on her husband. She falls prey to a couple of thugs.

Her husband goes to a black magic priest to get vengeance. This involves hallucinations, possession & murder. One scene make me howl with laughter, others made me cringe in disgust.

The insanity escalates until the explosive ending. This features a mix of practical & optical effects.

Warning: Contains necrophilia & rape.

Thanks to Maycon Guedes for recommending this film.
