The little information I have is straight from IMDB. It appears that there are 20 different segments. Joel and Ethan are listed as having directed the first. Gus Van Sant, Jean-Luc Goddard, and Alexander Payne are some of ther other notable American filmmakers involved. Not surpisingly Steve Buscemi is in the Coen directed arrondissement. If you have any other information please share it in the forum.
