A trailer of a report on A Dangerous Method- a 2011 German-Canadian historical film directed by David Cronenberg and starring Keira Knightley, Viggo Mortensen, Michael Fassbender, and Vincent Cassel. In 1904 a Russian woman named Sabina Spielrein (Keira Knightley) arrives at Carl Jung's (Michael Fassbender) clinic, seeking treatment for hysteria. Jung is eager to test Sigmund Freud's (Viggo Mortensen) theories on Sabina and, in fact, successfully treats her. Two years later Jung and Sabina meet Freud in person, and Jung takes over the treatment of Otto Gross, whose influence leads Jung to begin an affair with Sabina, contributing to a rift with Freud.
