My mind is blown...
First of all, I don't like this film (Vase de noces, Pig ____ movie). I think it is awful. However, I decided to click on the director and see if he has directed any other films. I didn't expect to find that the film he directed after this one was called Of The Dead (aka Des Morts). Of The Dead happens to be one of my all-time favorite documentaries. He was one of three directors, wrote part of the film and also did cinematography and editing.
I have a new-found respect for Thierry Zeno. How one can go from making a horrible art film featuring sex with animals, etc. to making an entrancing study of death and how humans cope with/react to it is beyond me.
If you're a fan of the more graphic 70's mondo films/shockumentaries, I highly recommend Of The Dead. (http://www.imdb.com/title/tt0245863/)
