'Bewitched' aka 'Gu' (1981) – Kuei Chi-Hung.

Revenge is a dish best served with an extra portion of gastric slime in the Shaw Brothers sordidly Satanic, morbidly maggot-infested Black Magic body shocker 'Gu'. Once holidaymaker, Stephen (Fei Ai) returns from his sojourn in sultry Thailand, he grimly discovers that he brought back more than spicy snapshots of, Bon Brown (Lily Chan), his beauteous, yet bizarrely vengeful, beach-frolicking lover! Plagued with mad visions of his daughter's increasingly malign nature, Stephen is arrested, summarily sentenced to death for the brutal slaying of his child. The once cynical cop, Bobby (Melvin Wong) stoically exposes those cruel instigators of the curse that evilly compelled, Stephen to commit such a monstrous act of infanticide!

Kaleidoscopically garlanded in grisly, dayglo-dripping necromancy, 'Bewitched' remains a hallucinatory, fascinatingly visceral example of vintage HK Body Horror. Director, Chi-Hung proves himself singularly adept at staging nauseating scenes of luridly flesh corrupting sorcery! Mean-spirited, and visually striking,'Gu' is steeped in stomach churningly graphic manifestations of blasphemous Black Magic maleficence! While disturbing, Bewitched is aesthetically sublime, the exquisite Thai locations are dazzling, and our Black Magic beleaguered protagonist's gruesome travails climaxes in a hyperbolic, mythically mental, monk vs sorcerer showdown. Far-flung, far out, but far from formulaic, the queasy far Eastern shocker 'Bewitched' casts a wickedly captivating spell that cannot be broken!
