If you loved Le Samouraï, try Army of Shadows
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Jean-Pierre Melville, and they both carry the cult, devastating, dread, foreign gem mood tags, and they sit in Drama / Thriller territory. If that's the register that drew you to Le Samouraï, the second film will land in a comparable space — through a different lens.

What Army of Shadows is
Dawn, Marseilles winter. A single Gestapo heel cracks cobblestone. One man claws free of a transit cell, his breath still smelling of fear. Lose the war, lose your shadow first.
