Michial Farmer hosts a a conversation with Danny Anderson and Nathan Gilmour on "Star Wars: A New Hope." Focusing on the movie's place in film history and more specifically in the career of George Lucas, the trio talks about its status as one of the first summer blockbusters; the influence of Joseph Campbell's mythological criticism on the film; and what, despite the film's shortcomings, makes it the sort of movie that shapes a whole generation's sense of the universe. Among the people, scenes, and other realities discussed are John Williams, monomyth, and Harrison Ford.
