Here's the basic premise: Albert C. Barnes collected a whole bunch of Impressionist, post-Impressionist, early Modern and African art in the first half of the 20th century, back when the U.S. art establishment hadn't really embraced such artists as Matisse, Cezanne, Renoir, Van Gogh and other now-considered Masters. Now, sixty years following his accidental death, the very critics, aristocrats, politicians and other establishment representatives he hated, have gotten their hands on his collection and will soon open a new museum displaying the pieces -- against the wishes of Barnes and the stipulations set in his will.
The documentary follows the history of the Barnes Foundation through its David-and-Goliath type struggle to protect the man's legacy and collection from its many enemies (and pseudo-villains) and the debate it has provoked. I guarantee you'll have a lot to talk about once the film is over (you should share your thoughts over at the Doc Talk post).
The clip below features a number of the film's talking heads discussing one of the attempts at a sale of the Foundation's art collection and the reasons why such an idea "isn't discussable."
