When October arrives in the Berkshires the annual fall foliage display gets some real competition from Barrington Stage Company when it presents a great work of literature on stage. In recent years we have seen The Crucible and To Kill a Mockingbird, and on October 3, 2012 the company will undertake its most difficult production to date, Lord of the Flies. Written by Nobel Prize winner William Golding, and adapted for the stage by Nigel Williams, it is a difficult work to do convincingly on stage because it is a story about boys, and best played by actors who approximate their age and appearance. That’s quite a challenge to pull off. But it appears that Barrington Stage has done it. Just look at the cast they have assembled.
