http://www.sundancechannel.com/iconoclasts Sean Penn answers the question: What is an Iconoclast? In the "Iconoclasts: Sean Penn + Jon Krakauer" episode of "Iconoclasts," Into the Wild, Jon Krakauer's bestselling novel adapted for film by Sean Penn, serves as a roadmap for their journey to Alaska. The two retrace backpacker Chris McCandless' steps along the Stampede Trail to the bus where he was found dead 15 years ago. While driving, flying in a helicopter and hiking to the shrine-like bus, the duo share a deep connection to the Alaskan landscape and discuss their thoughts on McCandless' spirit of adventure, their common bond with nature and the creative process it inspires. This episode includes music from the Into the Wild soundtrack composed and performed by Eddie Vedder. Directed by Joe Berlinger. ICONOCLASTS airs Thursdays at 10pm on Sundance Channel.
