A Dangerous Method (2011)

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. Gross' influence leads Jung to begin an affair with Sabina, contributing to a rift with Freud.
