Hex (1980) Chih-Hung Kuei

A woman, who believes she has murdered her abusive husband, then sees him return as a vengeful ghost.  

After making successful thrillers, action films, and comedies, director Kuei Chih-Hung put his first "Hex" on the audience. This eerie, frightening, supernatural, mystery thriller was so effective it led to "Hex Versus Witchcraft" and "Hex After Hex". What starts as an Asian variation of the classic French suspense film "Les Diabolique" becomes an exercise in fervid and frightening Hong Kong horror as one ghost after another appears to wreak havoc, insanity, and death
