Keira Knightley is set to shock fans with saucy spanking scenes in her sexually-charged new movie "A Dangerous Method."
 
The film focuses on the relationship between famed psychiatrists Carl Jung and Sigmund Freud, who are played by Michael Fassbender and Viggo Mortensen respectively.
 
Knightley plays a disturbed Russian patient who embarks on a scandalous affair with Jung, and the raunchy film footage shows the pair locked in a steamy sex scene and another with the actress bending over and being spanked.
 
The David Cronenberg film is due for release later this year.
