Quod erat demonstrandum

Not only the physical elements of mid-1980s Romania are captured in "Quod erat demonstrandum," but also the intangible atmosphere of cautionary hope, fear, and betrayal that permeated that society. Andrei Gruzsniczki's sophomore feature, handsomely shot on black-and-white film, takes a progressively involving look at two academics who have run afoul of the Securitate (Romania's secret service), revealing the compromises of the soul that many were driven to under the regime.
