British actress Keira Knightley nude from A Dangerous Method (2011)
The plot revolves around the founders of psychoanalysis Carl Gustav Jung (Michael Fassbender) and Sigmund Freud (Viggo Mortensen) and their complex relationships with smart and beautiful patient Sabina Spielrein (Keira Knightley).
The girl evolves from a hysterical, unable to control her own body, into the mistress of her doctor, and then into his colleague-psychiatrist. Mental disorder Spielrein was caused due to violence against her. As a child, she was subjected to the physical punishment of his father, but the “discipline” brought her pleasure, that is, exposed sadomasochistic tendencies.
