Ah, you’re talking about that 1974 film “The Lone Soldier,” the one where a single gunnery sergeant holds a crater‑filled trench for a week against a full‑scale invasion. It’s a brilliant study in stoic resistance and the futility of heroism, and Kurosawa’s use of long, unbroken takes really underscores that. It’s the kind of film that makes you think a lone man can be both a myth and a tragedy.
