A musician (Michael Brandon) is stalked by an unknown killer who's blackmailing him for an accidental killing of another stalker. But is everything what it appears to be?

The film opens with a great shot of drums from overhead and a beating heart, knowing that Argento is in the middle of his most stylistic period. Even the man with white gloves and disturbingly childish mask taking photographs is classic Argento.

I liked the concept of the images burned on to the retina, and I enjoyed the humor of having a character named "God" and the "Hallelujah" chorus. This being the last Ennio Morricone score in an Argento film was not lost on me, as the musical style shifted greatly after this one. (Not necessarily in a bad way -- Goblin and Simonetti are incredible.)

I was surprised to see homosexuality being so openly discussed in a film from this year. Maybe in Italy it was more acceptable than in America? Either way, an interesting addition.

The drummer of a rock and roll band Roberto Tobias (Michael Brandon) sees a man wearing sunglasses stalking him everywhere. He follows the man to a derelict opera house and when he confronts the stranger, he pulls a knife. However Roberto accidentally stabs him in self-defense and the man falls from the stage to the floor. Out of the blue, a spotlight is turned on and Roberto is photographed in the crime scene by a masked person on a theater box. Roberto leaves the place and returns home. On the next morning, he reads the newspaper the news about a stranger called Carlo Marosi that was murdered. During the night, Roberto and his wife Nina (Mimsy Farmer) welcome friends and Roberto finds a photo of the previous night entwined with his vinyls. He tells the truth to Nina and their maid Amelia (Maria Fabbri) overhears the story. While Robeto meets his friend Godfrey (Bud Spencer) to ask for help, Amelia schedules an encounter in the park with someone to blackmail with the photos she had found in the apartment; however Amelia is murdered in the park Meanwhile Nina's cousin Dalia (Francine Racette) arrives to stay with Nina. But soon Carlo Marosi appears eating at a restaurant and calling someone to meet him. What has happened in the opera house?

"4 mosche di velluto grigio" is a flawed film with am intriguing title. The atmosphere is suffocating most of the time; the camera work uses unusual angles and positions; the cast has good performance. But the plot point with the identity of the killer is weak and quite senseless. My vote is six.

Title (Brazil): "Quatro Moscas Sobre Veludo Cinza" ("Four Flies on Grey Velvet")

Deluxe giallo from writer-director Dario Argento, with a presentation so stylish it threatens to overwhelm the plot. Dedicated husband and drummer for a rock band angrily confronts a mysterious man who's been following him; they scuffle and the stranger ends up stabbed with his own knife. No one is around to help the shaken musician, but there is one witness: a person in costume with a camera. This isn't a blackmailer--they don't want money--but the musician is quickly taunted with photos and notes...and soon, the people closest to him start dropping like flies. Argento shows an uncanny grasp of character here, and his roster of victims and suspects is delicious (there's also a scripture-quoting con-man who acts as a lookout, a terrified postman afraid of delivering the mail and a gay gumshoe hired by the protagonist who hasn't solved one case in his last 87!). Argento is a cinematic madman; his screenplay might not hold up under close scrutiny, but it's hard to nitpick with the small details when the end results are this tantalizing. *** from ****
