Playwright Mike Poulton spoke to a British contingent at the Morgan Library last week about adapting Hilary Mantel’s Man Booker prize-winning novel, Wolf Hall, for the stage. Tony-nominated Wolf Hall, parts I and II, about Thomas Cromwell and Henry VIII, his wives and politics, is now wowing audiences at the Winter Garden Theater. Poulton said he usually works on material when the author is dead. This time, he made an exception when he met Mantel, and they collaborated well together. Ah, a harmonious moment for writers!
