Nina Paley’s new “potential-possible-maybe-feature film” project is Seder-Masochism, and she’s posted a clip called “This Land Is Mine,” which she envisions as the final scene of the movie. “This Land Is Mine” is a history of the Holy Land and all the blood spilled over the years by various parties who laid claim to it. Her web page for the short features a full cast of characters, with historical notes, and, of course, the wonderful video itself.
