The film's plot seems somewhat elusive so far (I've heard murder and very little else) but Chris Alexander did call it "an erotic, violent fever dream driven by mood, music and atmosphere" which could be either brilliant or awful, you know how it goes.
Of course, this won't be Peter Murphy's first appearance in a horror film (or any films, recalling Twilight.) The Hunger, a vampire flick featuring David Bowie, has a memorable opening sequence that includes Peter Murphy singing Bela Lugosi's Dead. Nivek Ogre also made an appearance in Repo! The Genetic Opera.
Of course this wouldn't be the first time a film which seems promising is announced and then flounders, but I'll keep my eye out for Peter and Nivek and see if anything else comes to light.
Assuming the film makes it out of development, would you go to see it?
