Documentary filmmaker Ross McElwee and editor Marilyn Levine. He made the film, "Sherman's March," in which he set out to trace William Tecumseh Sherman's march to the sea -- but it really traces his entanglements with Southern women along the way. During the editing of that film, he and Levine fell in love. McElwee's new film, "Something to Do With The Wall," began as a story about the eternal presence of the Berlin Wall, but ended up a story of the wall's breaking down.
