Not as relentlessly Decasian as the trailer suggests, actually settles down into a normal storytelling groove of interview material for a good while, but punctuated by Natan’s papier-mache-headed stand-in, a few effects shots of a wall of posters, and that voiceover by The Film Itself. These are all evocative additions – the poster gallery returns re-postered before and after the nazi invasion, and some of the scant footage of Natan himself, at his trial, has him repeatedly covering his head with a newspaper. This is already more thoughtful stylistic presentation than most documentaries get, then the voiceover and bookending Melies stories put it over the top.

Plus the story is killer, one of those subjects that researchers dream of – a chance to correct the wrongs of history. Bernard Natan isn’t set up as a saint, but at the very least an important figure in history, a founder of French cinema who deserved a better end and reputation than he got. The directors even scored an interview with the academic who brought the unfounded rumors and nazi-era smears into the modern age, a villain of the picture though he doesn’t seem to realize it.
