How I Unleashed World War II (Polish: Jak rozpętałem drugą wojnę światową) is a 1970 Polish comedy film directed by Tadeusz Chmielewski and based on Kazimierz Sławiński's novel "Przygody kanoniera Dolasa" (The Adventures of Dolas the Cannoneer). It was shot in Sochi, Baku, Poświętne and Łódź, among other places.
In a particularly famous scene, Dolas is questioned by a German-speaking Gestapo officer in Austria and answers that his name is "Grzegorz Brzęczyszczykiewicz"; the officer gets increasingly frustrated trying to write the fictitious Polish name.[2][3]
