Investigation of a Citizen Above Suspicion: Elio Petri’s film certainly is politically charged and courageous; very much a product of its time and place, thematically. Gian Maria Volonté creates a character that is unpleasant to watch, but at least is interesting; his acting is borderline histrionic, but that’s part of the aesthetics chosen to tell the story, alongside Ennio Morricone’s stylized score, Luigi Kuveiller’s interesting camera work and Ruggero Mastroianni’s editing (all a reminder that the story is a satire, should not be taken too seriously, even if the message is important for the filmmaker.)
