Until I posted this review, only 8 people had reviewed Il demonio and I feel like that's a real shame that it does not get the attention of some of Bava's or Fulci's films. In fact, I don't have hard proof of this but I believe Il Demonio was Fulci's inspiration (in part) for Don't Torture a Duckling.
Il demonio is a genuinely disturbing film and there is no way that it's not a classical inspiration to later films about witches and witchcraft. Like Fucli's later film, Brunello Rondi set his film somewhere in an undeveloped area of rural Southern Italiy where superstition and ignorance prevent women from expressing themselves sexually or at all as individuals, and even in the instance of mental illness or emotional disturbance, families abuse their sick relative and authoritarian religious figures abuse and take advantage of mentally unstable people, particularly sexually abusing women and young people.
Il demonio may even be landmark for its time, i am not enough of an "expert" about film to say for sure - because it challenges the Roman Catholic Church head-on in a way that craftier arthouse flicks or more satirical horror films about Satanists or hippies did not in the 1960s.
A bleak portrait of a woman abused by her father and sexually molested by religious figures and eventually other men does serve as a mirror for Don't Torture a Duckling nearly a decade later with its theme of religious abuse and a very specific character rejected as a witch by the entire town for having mental health issues or emotional disturbance after losing her infant child.
I just wish Il demonio had been in color. One of my gripes about Don't Torture a Duckling which keeps me from rating it a 10 as a giallo is Fulci's outright derision and snobbery towards Southern Italian peasants (Fulci was born in Rome) that is illustrated by how ridiculous most of the peasants are and how oppressive BROWN is throughout the film. Maybe that's how Fulci felt, maybe he was trying to communicate oppression by lack of color, but Southern Italian culture is generally the opposite - so colorful, bold and theatrical that I really do wonder what Il demonio would have looked like in color. I bet it would have won awards.
