Bob Le Flambeur (1956)

Plot:  French film noir. A gambler in the Paris Montmarte district, down on his luck, decides to rob a Casino of millions.
Stars: Isabelle Corey, Roger Duchesne

Plenty of great atmosphere (50s Paris) and "Bob" is an interesting character, but the "Heist" part is rather dull, and the movie takes too long to get going.  85 minutes of story stretched out to 102.  Like many of Melville's movies the whole thing is very stylish - but unreal.  Isabelle Corey shows flashes of beauty.

Summary: An early Melville Film-noir. Not bad - but Melville does the same thing better, in the 1960s.
