We move to Bucharest, Romania where the music was recorded, sound fx recording and cutting begins and a three day re-shoot. We then move to the final stages of the movie at Francis Coppola's winery in Napa Valley which doubles as a mixing stage. Walter then takes us on a tour of the human brain where he attempts to answer the question, "Why on earth do we do what we do?" We wrap up with a few questions from the audience.
