That looks pretty interesting, I'll check it out. I would also recommend from the same era of Czech cinema and dealing with a similar period if not necessarily the same theme, The Valley of the Bees and The Devil's Trap by Frantisek Vlacil. And, if you're in a more adventurous mood, also Marketa Lazarova. Superb stuff right there.
If you are into this you defo need to watch this:

Already have! It's in my all-time top 20. Superb film, very weird and disturbing, and Rudolf Hrusínský's performance is amazing. Glad to know another here has seen it! Juraj Herz's Morgiana and The Beauty and the Beast are also great.
Well I am Czech so I am quite familiar with it
