Christopher Plummer “comes naturally to his noblesse. It has served him well. In roles ranging from the creepy von Trapp to a fantastically neurotic Iago to the crusading Mike Wallace in the 1999 film “The Insider,” he has consistently thrilled audiences with the kind of voice and bearing that used to be taken for granted in an actor. Still, for all its high-tone glories, his career — nearly 200 television and movie roles, by his estimate, and stage productions too numerous to count — has thrived on his eagerness to strip away that noblesse and reveal the human muck beneath, the rot in the royalty.”
