An Officer and a Spy (2019)

France's Dreyfus affair seen through Georges Picquart, the intelligence chief who found proof that the convicted Jewish captain was innocent, then watched the army try to silence him rather than admit it. Adapted from Robert Harris's novel, it is meticulous about uniforms, offices and forged files, which makes the opening stately but the cover-up chillingly plausible. Picquart's own antisemitism is kept in view rather than polished away, a fair touch in a film that could easily have made him a spotless hero. It won the César for best director, and Roman Polanski's own legal history has colored its reception for many viewers.
