Lie back on the couch and prepare for some sexual healing in A Dangerous Method (2011). Viggo Mortensen and Michael Fassbender star as fathers of psychiatry Sigmund Freud and Carl Jung, entwined in a turbulent teacher/student relationship in early 20th century Zurich. Tempering the film’s more bromantic aspect is Keira Knightley, who’s bound to please as Russian mental patient and repressed BDSM fanatic Sabrina Spielrein. When Jung's "treatment" of Sabrina blossoms into a full-blown affair, his relationship with his mentor is strained to its limit. Sometimes a cigar is just a cigar, but yours will be more like a steel pipe when you see Keira's Freudian (nip) slips during a duo of erotic spanking scenes. Add some historical hootage from Sarah Marecek and some see-through racktion from Anna Thalbach to the mix, and you've got everything you need to rile up your raging Id.
