Wow! Looks like Oscar is not available on any streaming services in the world!

An Austrian Jewish teenager exiled with his family to a village in the Vicentine Alps wins over the locals, and even the podestà’s sons, by sharing his forbidden love of jazz and joining the town band. After the German occupation following September 8, they flee with the community’s help, linking up with partisans who guide them safely across the Swiss border. Loosely based on jazzman Oscar Klein’s 1944 escape.
