Corpse Mania (1981)

The movie's about a psychopath who kills women and rapes them after, to the layman's this criminal act is called "necrophilia" (sex with the dead).

It is implied that a man has sex with a few female corpses through out the movie, the actual act is never shown. One scene for instance shows the antagonist rubbing a dead girls body with a wash cloth, her naked body can be seen.

One of the more explicit scenes shows a man watching at a dead girls naked body while she's completely covered in hundreds of maggots and worms.

A Few people get stabbed to death through out the movie, a woman gets decapitated near the end of the movie (Bloody).

Not recommanded to younger viewers (below the age of 16) because of it's necrophile content.

A man who hides his face with a scarf can be seen stalking people with a large knife, most of the scenes with the killer involved could be concidered as intense.
