Unruh

Pyotr Kropotkin was one of the lesser-known revolutionary figures in nineteenth-century Russia. Cyril Schäublin's "Unrueh" ("Unrest" in English) focuses on Kropotkin's time in Switzerland, where he became an anarchist. Part of what the movie deals with is how conditions in the factories drove people to leftism. I don't know if conditions in Switzerland's factories were as bad as in, say, those in the US or England, but there's a reason why revolutionary thought arose in such settings.

It's the sort of movie that deliberately movies slowly to allow the characters to develop; I guess that's our stereotype of the Swiss, right? I don't know if I would go so far as to call it a masterpiece, but it's worth seeing. As it's a pretty obscure movie - it doesn't even have a Wikipedia entry - you'll probably have to find it in a video store rather than on streaming.
