Storyline
Did you know
- TriviaArgento's usual collaborator Ennio Morricone scored the film but had a major argument with Argento over some tracks Argento didn't want in the film. As a result, the director and Morricone would never work together again until 1996, and the rock group Goblin would eventually become Argento's regular composers.
- Quotes
Gianni Arrosio: You know, this case is a real challenge. Fortunately, the odds are in our favor.
Roberto Tobias: The odds?
Gianni Arrosio: Exactly. You see before you a fully-fledged, highly-qualified private investigator with an extensive knowledge of modern science at his very fingertips. And, in spite of this, in three years of honest practice, I haven't solved a single case.
Roberto Tobias: Not even one...?
Gianni Arrosio: Not even one.
- Crazy creditsYou have just seen Four Flies on Grey Velvet.
- Alternate versionsThe original U.S theatrical release was cut mainly for pacing as well as shortening the tub love scene and a decapitation for a PG rating.
- ConnectionsFeatured in Il mondo dell'orrore di Dario Argento (1985)
A drummer for a prog-rock band finds himself being followed by a mysterious figure for an entire day. Losing his rag, he turns pursuer and ends up chasing the guy into a disused theatre, where he ends up stabbing the guy in a brief struggle. That's bad enough, but the person wearing the creepy mask and taking photos during the struggle is going to cause our guy all sorts of problems, as pictures start turning up in our hero's home, and someone is stalking around his house at night.
Who did our man kill? How does the cleaner know who the blackmailer is? And who keeps having flashbacks to an abusive father? A private investigator steps in to help, but I'm saying nothing more, except to say the bodies start piling up before our drummer can discover who's really behind the killings, and nothing is as it seems.
Like Bird with the Crystal Plumage and Cat O' Nine Tails, this early Argento giallo has a healthy dose of humour thrown to the proceedings, what with legend Bud Spencer playing God(frey), a tramp who helps out our drummer guy, a postman who keeps being berated and beaten, and the ultra-camp performance of the PI (a recurring theme in Argento's early films). The crazy visuals are brilliant throughout, and although I wouldn't say it's an outright classic (like Cat O Nine Tails, there's a lot of messing around), it's still a really good giallo.
Also like Cat O Nine Tails, there's a fairly dodgy scientific explanation for things that some people may find a bit hard to swallow, and instead of the killer being discovered through an earlier clue, they're kind of stumbled upon instead (and quite easy to guess). However, you've got to check it out.
