@ arsaib:

True words!

Just because you mentioned his "more esoteric stuff": Have you seen "The silver globe"? I heard that it will be released in the US within the next few months and if you haven't already you should check this one out. 
I watched it last week (it was shown only ONE time on german television in 1990 and fortunately, a friend of mine taped it) and was frightened and impressed at the same time. The references to Zulawski's other films seemed quite thin to me (at least, in the beginning) and the most noticable difference between this film and his other features were the dialogues. As there were almost no dialogues. It is partial an adaption of the so-called "Lunar Trilogy", written by Zulawskis grand-uncle Jerzy and almost every sentence is a philosophical assumption or even a little discourse of its own. So, not according to the four other films I've seen by him up to now ("L'Important c'est d'aimer", "Possession" and "La Fidlit"), I was extremely exhausted after this three hours but the concentration was worth it as I conformed a lot with Zulawskis points. 

Once, a critic wrote that this film probably could have been Zulawskis breakthrough if he would've been able to finish it in 1977 and the whole affair indeed seems as an incredible injustice to me right now.
