As Letters from Iwo Jima goes on general release, Francine Stock talks to Clint Eastwood about this and Flags Of Our Father, his dual film project - war films that ultimately argue against war, contrasting takes on a crucial battle of the Second World War, one from the American perspective, one from the Japanese. The programme assesses the impact and range of Eastwood's career, particularly his latest works, and asks if he isn't one of the most subversive directors working in America today.
