Such an amazing movie! It's a Hungarian movie, well more like art film, about a very bizarre true insident that occured in the village of Nagyrév, Hungary. There is no real dialoge, or much speaking at all, so no worries if you are not Hungarian. They do sing a traditional Hungarian folksong near the end of the movie, but its got subtitles. Although i may be biased, since its an art movie...and its from my homeland, but it really amazing. Its kind of hard to understand, but once you understand the weirdly hidden plot, the movie becomes absolutly brilliant. :]
You can find the movie on netflix, but i'm not sure where else.
