If you loved The Idiot, try The Quiet Duel
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 Akira Kurosawa, and they sit in Drama territory. If that's the register that drew you to The Idiot, the second film will land in a comparable space — through a different lens.
What The Quiet Duel is
Casablanca meets The Doctor's Dilemma. A surgeon treats himself for syphilis in secret. Cary Grant carries a similar era's repressed emotions.
