Kurt Andersen talks with the Pulitzer Prize-winning playwright and actor Tracy Letts, who stars as half of American theater’s most notoriously bitter couple in Who’s Afraid of Virginia Woolf?

Plus Kurt talks with George Saunders, maybe America’s most important writer of short stories, who miraculously does dark and funny and poignant all at once.
