Investigation Of A Citizen Above Suspicion begins like a giallo, but soon pushes beyond even that genre's outr boundaries, playing like a fever dream.

Its portrait of a loner and his lusts comes up frighteningly fresh, and the whole conceit would collapse without the muscular, rousing presence of Gian Maria Volont in the central role.

A paranoid police procedural, a perverse parable about the corrupting elements of power, and a candidate for the greatest predated Patriot Act movie ever ...

Volonté is a snarling beast, delivering a masterclass in muscular acting and irrepressible self-belief.
