Dulles, Va. - AOL vice chairman Ted Leonsis this week premiered a new documentary film that he served as a producer on at the Sundance Film Festival. In a blog entry, Leonsis wrote on Friday that his team is "still working feverishly on a domestic (distribution) deal but it looks like we may have to wait until after the festival to close on one." "Nanking" chronicles the Japanese invasion of Nanking, China in the early days of World War II, and the heroic effort of a small group of Westerners to save as many civilians as possible.
