Stavisky

Irresistible charm and talent helps Serge Alexandre alias Stavisky, small-time swindler, to make friends with even most influential members of French industrial and political elite during the early 30s.

The film began as a commission by Jean-Paul Belmondo to the screenwriter Jorge Semprún to develop a scenario about Stavisky. Resnais, who had previously worked with Semprún on "La Guerre est finie", expressed his interest in the project (after a gap of six years since his previous film); he recalled seeing as a child the waxwork figure of Stavisky in the Musée Grevin, and immediately saw the potential of Belmondo to portray him as a mysterious, charming and elegant fraudster.

It seems like most historical French films either take place during World War II (focusing on the occupation) or are in some way related to Algeria. This one really has neither, because it is set between the two world wars, with some interesting supporting characters (Leon Trotsky!). I had never heard of Stavisky, but now I'd be curious to know more (despite having no real passion for French history).
