If you loved Naked Bullet, try United Red Army
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 Kōji Wakamatsu, and they sit in Drama / Thriller territory. If that's the register that drew you to Naked Bullet, the second film will land in a comparable space — through a different lens.
What United Red Army is
Mid-winter mountains. Frozen boots stomp snow. Two student factions fuse into one. Training turns to surveillance, loyalty tests to life-and-death.
