London - Ewan McGregor has directed his first feature film - an adaptation of Philip Roth’s 1997 novel American Pastoral - and insists you do not have to be American to tell an all-American story.  American Pastoral tells of a family living in America in the boom years that followed the end of World War Two.  Its hero is one Seymour “The Swede” Levov, a high-school athlete and all-round golden boy who marries a beauty queen and sets up home with her in rural New Jersey.  The couple, who are soon joined by a daughter called Merry, appear to be living the American dream. But cracks appear when Merry grows up to be a teenage radical fiercely opposed to the Vietnam War.
