Kurt Andersen and master film editor Walter Murch talk about the simple and complex tools we use to innovate in art.

Walter Murch is that rare creature — an artist almost universally considered a master in his field. He edits sound and images for movies. His credits include the Godfather, Apocalypse Now, American Graffiti, The English Patient, The Talented Mr. Ripley, The Conversation, and Cold Mountain.
