When it comes to truly loathsome characters in a giallo, few can match Giuliano Carnimeo’s The Case of the Bloody Iris, a film in which pretty much everyone is hateful, stupid, or more often, hateful and stupid.
Alan is a handsome aristocrat who enjoys velvet jackets, cravats, and murdering strippers. He marries a woman in hopes she will curb his homicidal outbursts, and his creepy estate is soon haunted by the ghost of his former wife.
All the Colors of the Dark works within the confines of the giallo, but it takes the genre further afield than had previously been explored, resulting in a dizzying psychedelic combination of straight-forward stalker/murder mystery, hallucinogenic psycho-sexual exploration, and straight up occult/devil worship horror.
It was common for Italian exploitation films to be graced with a soundtrack that was much better than the film surrounding it. Such is the case with Bruno Nicolai’s score for The Case of the Bloody Iris.
Despite Morricone’s much deserved reputation, it’s probably Bruno Nicolai who deserves to be crowned king of the giallo soundtrack. He wrote quite a few. Most of them are very good. Many of them are great. All the Colors of the Dark is the best.
The score maintains this blend of offbeat styles that still manage to operate as a cohesive whole, becoming tenser and more threatening. It makes perfect sense in a film about the unreliable nature of perception.
