Ken Loach, Britain's cinematic patron saint of the downtrodden, is taking on a piece of history he believes has been played down in his native land the country's history of imperialism in Ireland and elsewhere. A regular at the Cannes Film Festival with such films as "My Name Is Joe," "Sweet Sixteen" and "Land and Freedom," Loach returns with "The Wind that Shakes the Barley," a bloody saga of British against Irish and brother against brother during Ireland's fight for independence and subsequent civil war in the early 1920s.
