A sexy actress has her throat cut on a movie set with the cameras rolling and a shadow caught on film may be the murderer's...
This minor, low-budget entry in the giallo canon sounds better than it actually is and doesn't seem to take itself too seriously because the cast and crew of the film-within-a-film border on parody. Among the suspects and victims are an eccentric auteur, a disgruntled writer, some temperamental actresses and a few technicians with axes to grind and this insulated world gives the movie a claustrophobic feel -but breaking out in an extended chase sequence through the midnight streets of Turin only grinds the movie to a near-halt. The unusual finale takes place in a theater with everyone dressed as "Diabolik" -including the killer- but it's too little, too late. With only three murders and no gore, this threadbare thriller is reely nothing special.
