Investigation of a Citizen Above Suspicion
Elio Petri's best-known film is a scathing satire dealing with the abuse of power in high office and simmers with all the psychological tension of an intelligent political thriller.
Enhanced by a striking visual flair and a masterful score by Ennio Morricone, it features a seductively powerful performance from Gian Maria Volonté as an egomaniacal senior detective who murders his mistress and then deliberately leaves clues pointing to his guilt.
