I found the DVD of this movie at my public library and watched it at home. A curious DVD presentation in that it has no menu, it just starts and runs for almost 2 hours, mostly French and German with English subtitles.
I am a musician but only became familiar with Django Reinhardt in the Woody Allen movie "Sweet and Low Down" which featured a fictional character, a guitarist, who would almost faint at the thought of even meeting Reinhardt, his idol. So this movie is a good look at who the guitarist really was.
Reda Kateb, a Belgian actor, is very good as Django Reinhardt. Even though he had been playing for quite a while the story here picks up in 1943 France during the German occupation. Django had a double whammy against him, being a Gypsy and being a Jazz musician, two things the Nazis were against and killed many for. But he managed to survive because of his musicianship.
Good movie of an interesting musician in a difficult time. he didn't live much longer, dying at age 43.
