 With a voice that combines the boom of thunder with the breathlessness of Marilyn Monroe and a leaning posture that appears to be in eternal search of a lamppost, Mr. Barbour invests every minute he’s onstage with heavy-lidded, overripe languor.Some might call his performance de trop (well, in Paris they might).But hey, at least he shows signs of life, something otherwise perversely lacking in this tale of historic turmoil.In 2011, it was announced that he would play the supporting role of Jack Favel in the Broadway musical adaptation of "Rebecca".
