I've heard about this one before, and decided to check it out. It's a Russian animated film that loosely adapts the story of Countess Bathory. The animation is a cross between the National Film Board of Canada's stuff and Ralph Bakshi's more experimental work, and through pantomime similar to The Triplets of Belville, attempts to portray Bathory's history through almost fairy tale-like storytelling.
It's a hell of a thing, if you're interested.
Sounds interesting, I'll have to check it out.
