Strong performances make it hard to single out individuals but Anna Guthrie is an impressive Joan, wholly believable as the wide-eyed village girl terrified but inspired by her mission. Philip Kingscott is an ebullient but malleable Dauphin; Robin Thomson, a chilling Inquisitor; and David Elliot, a cavalier but courageous soldier. It's rare to see a complete production of a classic play on the Fringe, let alone in such a spectacular setting. Until August 24 (not 11, 12, 18).
