Anne MeElvoy reviews Paul Greengrass's new film Green Zone, which stars Matt Damon, who collaborated with Greengrass on The Bourne Supremacy, and Greg Kinnear. Set in the secure area in the centre of Baghdad that was the base for the international presence in the city, the film is based on the controversial book by the Washington Post's Baghdad bureau chief Rajiv Chandrasekaran which focussed on the final stages of the invasion of Iraq and the transfer of power to the Iraqis. Plus a discussion on the 'new' atheism. Opponents suggest that there is a new movement of more assertive atheists in society. On the eve of a Global Convention of Atheism in Melbourne Anne talks to the writer Charles Moore and the scientist and atheist Peter Atkins. Alex Butterworth, the author of a new book on 19th century anarchists, 'The World that Never Was', discusses the parallels with our own war on terror. And Bill Buford discusses his new BBC4 series, 'Fat Man in a White Hat' in which he enrols in a cookery school in Lyons to explore our relationship with the food we eat.
