I can't figure out how to quote a full Web page yet, so these are cut off, just click to read the full version.
PS - I am remiss in just noticing now that additional screenings are taking place at Redcat http://www.redcat.org/event/jean-rouch and L.A. Film Forum http://www.lafilmforum.org/index/Current_Schedule/Entries/2013/1/27_Jean_Rouchs_Horendi.html. Even better!!
