A moment in history with David Cronenberg
Director talks new film, Mortensen, and Knightley
Long before Muhammad Ali and Joe Frazier, Sigmund Freud and Carl Jung fought their own fight of the century. Jung had been Freud’s leading psychoanalytic disciple - until they quarreled and became bitter enemies. In “A Dangerous Method,’’ which opened Friday, Viggo Mortensen plays Freud, and Michael Fassbender plays Jung. David Cronenberg, directing his first feature since “Eastern Promises’’ (2007), serves as referee. The most important participant may be Keira Knightley, who plays Sabina Spielrein, a patient of Jung’s who also sought treatment from Freud.
