"This is the last film in the trilogy that began Andrzej Wajda's career as a director. Preceding this wartime drama are Pokolenie (1955) and Kanal (1957). Once again, Wajda presents a strong anti-war statement, this time in the personae of two men who are given orders on the last day of World War II in Poland to murder a leading communist. The orders come from the part of the resistance that opposes the new communist regime. One of Wajda's favorite performers and a friend, Zbigniew Cybulski, plays the man who eventually pulls the trigger and kills the communist leader -- and the results are not what he expected. In 1959, Popiol I Diament won in competition at the British Academy Awards and at the Venice Film Festival."
