If you loved Das Boot, try Underground
A bridge between a film you've already seen and one most people haven't. Underground has roughly 3.2× fewer votes than Das Boot — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Theyboth carry the foreign gem mood tag, and they sit in Drama / War territory. If that's the register that drew you to Das Boot, the second film will land in a comparable space — through a different lens.
What Underground is
Here's a film that seems to think subtlety is for cowards. During WWII, two arms dealers in Belgrade prosper by selling weapons to the Communist resistance. Decades later, old betrayals resurface amid the brutal reality of the Yugoslavian Civil War. It's quite a lot, perhaps even deliberately so.
