Have you seen the argentinian original? Good movie, worth watching!
Oh, just watched the trailer now... Lame, it bears little resemblance to the original... IMDB lists the same writer/director as the argentinian version, though...
Yes I have seen the original, I thought it was excellent. It is one of the very good international films of the last decade, along with Lives of Others, Incendies, Cell 211, Separation, etc
