Sean Penn is the authentic heir to Brando and De Niro - the ultimate anti-Hollywood icon whose fearsome talents are tied to fiercely-held convictions. Now, in this uniquely revealing biography, the Oscar-winning but famously press-wary star of Mystic River, The Interpreter, and Dead Man Walking tells his own story, in the company of exclusive tales and insights from his closest friends, family and colleagues - from Jack Nicholson to Dennis Hopper, Woody Allen to Christopher Walken, Bono to Susan Sarandon.
