Kurt Andersen talks with writer Paul Theroux about the fierce rivalries that motivate artists to their best — and their worst. Theroux tells why his long friendship with V.S. Naipaul fell apart. We’ll hear a battle of the bands like we’ve never heard before, and watch the heroes of Hong Kong action films put up their dukes. Plus: why the London subway map broke the laws of cartography; and novelist E.L. Doctorow talks with Kurt about his new book, The March.
