I was pointed to a great documentary Fiume o morte! (Fiume or death) which is free to watch on Vimeo. The documentary tells the story of the occupation of Rijeka, known in Italian as Fiume, by the fascist Italian poet D’Annunzio and a small army of Italian soldiers in 1919. Despite opposition from the Italian government, the occupation of the city on the Adriatic coast of Croatia attracted thousands of Italian youth. The documentary tells the story though a creative mix of recreation, historical evidence, humour and reflection. Multiple amateur locals play D’Annunzio and much of the narration is in Fiumano, the dialect of Italian still spoken by some in Rijeka.
Watch it!
