Director Paolo Fazzini introduced me to this world with his important documentary, Hanging Shadows: Perspectives on Italian Horror Cinema. With the exception of a couple of books, Italian Horror Cinema has been vaguely recognized as a merited part of film history. Native Italian countryman Fazzini exposes the men behind the cameras and other plays involved. He does this in a way pertaining to many aspects of Italian Horror Cinema. Between interviews, various killing sequences are featured through Hanging Shadows. Made for the documentary, these murders pay deliberate homage to the Italian maestros discussed.
Like most Italian films, the dialogue is very fast in comparison to the subtitles. You may end up rewinding scenes to see what Ruggero Deodato said, but it is well worth it. Nothing said in Hanging Shadows is insignificant or unimportant to any fan of Italian Horror films.
