Renaissance man Simon Callow talks about "Hello Americans", the second book in his multi-volume biography of Orson Welles and his ongoing inquiry into Welles' life; explains how writing was his first passion, long before he began acting; considers how his manifesto against a director-driven theatre in his book "Being an Actor" has been tempered since he began directing himself; and recalls the experience of creating the role of Mozart in "Amadeus" opposite the legendary Paul Scofield.
