Easily one of horror greatest piece. A true classic An American writer staying in Italy, starts to get
threatening phone calls, at the same time, women
starts to get murdererd, and the murders are all
tied to him. Especially since all the murders are
exactly same as in his recent book.
Tenebre, like Mr. Argento early film Profondo Rosso,
he uses very unique horror tactic, which many
people didn't see back then.
