If you loved Cul-de-sac, try An Officer and a Spy
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 Roman Polanski, and they sit in Drama / Thriller territory. If that's the register that drew you to Cul-de-sac, the second film will land in a comparable space — through a different lens.
What An Officer and a Spy is
A Parisian courtyard, autumn leaves, a torn document. A military court decides, a family watches, a man is led away. Polanski revisits a famous injustice with characteristic nuance.
