Deep Red
Technically speaking, 1975’s Deep Red (a.k.a. Profondo Rosso) isn’t about the supernatural. That isn’t a spoiler; Red is a giallo, an Italian thriller in which often insane, but utterly solid criminals commit awful crimes. Director and co-writer Dario Argento didn’t get into occult horror until his next feature, Suspiria, and Red serves as an informal bridge between that phase of his career and his early giallo phase, which included movies like The Bird With The Crystal Plumage and Four Flies On Gray Velvet. Like those early films, Red features gruesome murders, bright colors, and a mystery with a real-world solution. And as with those films, Red doesn’t truck with ghosts, witches, or any sort of inhuman monster. Yet it’s almost impossible to walk away from this story of a jazz pianist on the hunt for a killer without the impression something unusual just happened. After all, a house doesn’t need ghosts to be haunted.
